Sansui J33 loudspeakers

60 W Power Handling, 90 dB/W Efficiency and 45-20,000 Hz Frequency Range

There are speaker systems a hundred times the size of the Sansui J33 which can't offer nearly the sound quality. Power handling capacity is 60 watts, an advantage ordinary small speaker systems can't equal. Efficiency is an excellent 90 dB/W at one meter, meaning you can drive the J33 with a relatively low-powered amp or receiver without problems of lost dynamic during the loud passages. Then, to ensure that you get your music's worth when you play any true high fidelity source, the frequency range is a wide 45 to 20 kHz - strictly hi-fi , right systems - staggered from the center axis to the left and right respectively - are on the "outside" for ideal response in your listening area. The staggered arrangement of the speaker units within each system assures pinpoint stereo imaging.

 

Two-way Design and Mirror-Paired Units for Incomparable Stereo Imaging

Sansui packages the J33 in matched stereo pairs; we suggest you mount them so that the tweeter of the left and right systems - staggered from the center axis to the left and right respectively - are on the "outside" for ideal response in your listening, area.

The staggered arrangement of the speaker units within each system assures pinpoint stereo imaging.

 


Luxurious "Piano" Finish on a Compact Speaker System

The Sansui J33 is finished in a deep black luster much in the same way a fine piano is finished. First the surface on the high-density enclosure panels are filled, then two layers of special lacquer are applied, again sanded smooth. Three more coats of lacquer are applied,, again sanded with care, filled, then wax-buffed to a high shine. The entire process takes nine separate steps, and results in an enclosure surface so smooth and hard it can resist nicks and scratches to retain its beautiful luster over the years.

Precision Panel Joining Means Ideal Air-Suspension Performance

Here's one of the secrets of the realistic bass response in the j33 - air-tight enclosure cabinetry that acts as a "spring" to reinforce the rich resonance of the low frequency musical sound waves produced by the woofer. To enclosure solid joints, Sansui craftsmen use a "plain miter Joint" technique, angling the edges of the enclosure panels and fitting the corners with extreme precision.

Seamed-Sheet Cone Assures Deep Musical Bass in 21 cm Woofer

The uniformly distributed mass and even thickness of the cone materials offer ideal density without adding unnecessary weight. Shape, too is important here, for the woofer cone is not straight but curved - formed by seamed-sheet technique which discourages distortion of all kinds. Ideal internal loss contributes still more to rich bass response.

The cone is then suspended by a rolled surround for ideal compliance, retaining its mobility even at high-level driving. Response is smooth whatever the level because the magnetic circuit features a large-sized ferrite magbet forming an exceptionally strong magnetic flux along the specially-treated, low-mass voice coil. High power handling, unusually high efficiency for a compact and believable bass reproduction are the advantages.

One-Piece Soft-Dome Tweeter Spreads Crisp Highs

Soft-dome tweeters, such as that in the Sansui J33 are known for their ability to avoid "beaming". That is, their output is radiated evenly in an expanding arc pattern to reach every corner of your listening room. Our soft-dome diaphragm, formed of polyester fiber of ideal firmness and elasticity, is damped by a uniform coating of acrylic-based chemical agent to effectively control harmful resonance while assuring linear response to varying input levels.

The dome is formed with a rolled surround all in one piece. Tonal degradation, caused when domes and surrounds are separately manufactured and bonded together, is thus avoided. Heat and distortion, too, pose no problem. This is because we use a 13,000 gauss magnetic circuit, a light voice coil and a rigid voice coil bobbin.

Sansui J11 loudspeakers

World's First "Mini" Speaker with Passive Radiator for Double-Rich Bass

Sansui has solved a big problem in little speakers. We custom-designed a passive radiator unit for the miniature 2-way, 2-speaker J11 system. It effectively restores the realistic rich bass sound which most other "minis" forfeit for their small size.

Double-rich bass isn't the only advantage in the J11. nor is its small size - no taller than a wine bottle or much wider than a paperback book - the feature you'll appreciate most. Where Sansui audio technology really shows up best is in the distinct sound image reproduction from this unique system - strictly hi-fi in every respect.

The surprising depth of the bass is complemented by natural sounding midrange and crisp highs for tonal balance. Bearing in the high frequencies is no problem since the newly-designed dome tweeter disperses its sound waves uniformly over a wide arc. The special design of the solid aluminum enclosure also adds to the big-hearted authority of this modestly sized "mini" from Sansui where it's all hi-fi.

 

Light and Firm Diaphragm for Tight Bass from 10 cm Woofer

It follows that if the passive radiator is to deliver authentic sound reinforcement from the woofer, the woofer itself must be of the highest performance standards. Here we've developed very special cone paper by mixing two different types of acerose pulps to achieve lightness, firmness and strength. The woofer cone, 10 cm in diameter, weighs only 0,6 grams, yet can respond faithfully to amp inputs over a wide frequency range.

Linearity in the woofer is further improved with the use of a separate, resin-formed surround. Distortion particularly in the second harmonics, is never noticeable, even during high-level reproduction, since the large magnet offers a huge 9,000 gauss field, uniformly distributed by the precision machined pole piece. The voice coil bobbin is highly heat resistant for constant performance, another assurance of excellent performance in all practical audio situations.

 

Soft-dome tweeter has Polyester-Based Cloth Diaphragm Large magnet

What are the three major benefits of the soft-dome design in tweeters. One, wide dispersion without "beaming". Two, low resonance to avoid distortion. Three, crispness and musically in the high frequencies. These, crispness and musically in the high frequencies. These add up to explain the popularity of soft domes, especially in "mini" systems. But we've added a fourth important benefit in outs, a better Signal-to-Noise Ratio by forming the one-piece diaphragm/rolled surround of responsive but firm polyester based cloth, damped by an acrylic-based agent, this construction avoids the use of chemical agents in binding the core to the surround, and thus prevents tonal degradation. To achieve transparent highs extending well into the supersonics, we've given this remarkable tweeter a powerful 9,000 gauss magnetic, flux, combulling phase irregularities by mounting an acoustic equalizer behind the diaphragm.

ADS 500 loudspeakers

The System

The elements in a speaker function as a system only if the utmost care is taken in combining the individual components and dimensioning the cabinet to match the critical woofer parameters. The 500 drivers perform superbly in their modest size cabinet, with better results than many manufacturers achieve in enclosures several times its size,

You'll be amazed at the clean, accurate bass that comes from our 8" driver, and low frequency bass doesn't mean large woofers. Smaller woofers provide better dispersion in the midrange, and they excel in the musically important transient response. As a result, our smaller woofers provide open, better-than-transparent reproduction, extended to bass.

The ADS 500 reproduces the input signal as faithfully as possible, offering smooth full-range frequency response from a low organ tone to well beyond audibility, while providing superb dispersion and unsurpassed transient response.

 


The Tweeter

One great component the ADS 500 shares with our studio speakers is the unsurpassed 1-inch diameter soft-dome tweeter. It gives the 500 its unprecedented open clarity, super-wide dispersion, and silky smooth high-frequency response.

We don't know of another tweeter that works so accurately and efficiently as our 1-ich unit. That's because a magnetic flux of 360,000 nW controls a dome weighting a mere 0,2 grams, including he voice coil. By giving our tissue dome its own sealed acoustic chamber and by damping resonances with a unique sticky fluid, we have eliminated distorting break-up and coloration so common to paper cone, plastic , or metal dome tweeters.

Our tweeter is able to handle transients and musical details so faithfully that it's truly an ear-opening experience. And, in spite of its lightweight, this dome can tolerate substantial amounts of power. The metal voice coil stays cool in the very narrow magnet gap by radiating excess heat into a massive 1,2 lb magnet

 

The Woofer

Truly good two-way systems are difficult to design, because the woofer and tweeter have to cover a wide range of frequencies. The ADS 500 is a truly good two-way system.

The woofer of the ADS 500 covers a large portion of the midrange; up to 1,500 Hz. Because the human ear is extremely sensitive to distortion and coloration of these frequencies, we developed an unique woofer cone material that's stiff to move air for good bass, yet is soft and self-damping at high frequencies to prevent break-up and coloration.. Also, this material is light enough to handle musical transients quickly and cleanly. The woofer cone is then set into a soft suspension for efficient and accurate motion.

We don't think you should require a super amplifier to drive this speaker to high levels, so we built the needed magnetic strength into our drivers. Even a faifly low power receiver provides concert hall sound pressure in a typical Livingroom with a pair of ADS 500's

 

The Crossover

We are, indeed, pround of our drivers. But, they can only achieve their optimum performance with the right crossover. That's why we use heavy gauge open air, copper coils for perfect dynamic linearity and minimum power losses. And, that's why we have selected computer-grade metal-film capacitors for long-term stability and consistently excellent frequency response.

Kenwood KR-8010 receiver

If you're enthusiastic about today's less efficient, super-accurate speaker systems, you know you need a very efficient, super-power receiver to drive them. And if your ears are good enough, you know the value of lots of power to handle critical musical passages with any speaker system.

That's why we created the new KR-8010. with 125 Watts per channel, minimum RMS both channels driven at 8 ohms, from 20 Hz to 20,000 Hz with no more than 0,03% Total Harmonic Distortion, you've got all the power you really need.

But more important, the KR-8010 gives you an extremely clean, low-distortion signal at the same time. For example, the Signal-to-Noise Ratio through the phono input is the best you'll find on any receiver (90 dB). Its overall frequency response is matched precisely to the RIAA curve ±0,2 dB. And the tuner delivers sensitivity and selectivity that you'll really appreciate in signal-crowded-cities.

To shape that signal into music, the KR-8010 offers a full range of front-panel control, usually found only in esoteric separates and recording studios. Like tape dubbing while listening to another source. And dual FM muting levels, Mic input and fade control. Bass, treble and midrange tone control. And more.

Sherwood CDP-100 cd player

The compact disc just may be the most heart-stopping concept in sound since stereo. But the most heart-stopping feature of compact disc players has been their price. Now, with Sherwood's CDP-100, you can relax about money and really get excited about sound.

A tradition of affordable excellence.

Sherwood is well-known for high-quality audio products at affordable prices. And our new CD player is no exception. While others were still on first generation models, we combined advanced second-generation performance with a no-nonsense array of useful features. And we did it in a way that not only makes sense, but saves you dollars as well.

Three laser beams for better tracking.

Most CD players use only one laser beam. Sherwood put a three-beam laser into the CDP-100, because a three-beam system virtually eliminates distortion caused by spurious data from adjacent tracks.

Two filters, not one.

All CD's require filters, because the decoding of digital sound generates a sampling frequency which must be filtered out, or distortion will be heard.

Other CD players use one way steep analog filter; this can cause phase distortion. Sherwood's answer is to use a digital filter to double the sampling frequency, then use a more gentle type of analog filter for reduced phase distortion. The result; better sound at less cost.

Easy-to-use functional controls

Inserting a disc is easy, thanks to a "smart" motorized drawer under microprocessor operation. It even knows if you accidentally put the disc in upside down.

You can easily access any selection, and there's a two-speed fast forward and backward, so you can listen while you quickly locate the spot you want to bear. You can even set the CDP-100 to repeat the entire disc for continuous music.


 


 

Pioneer CS-A500 loudspeakers

3-way Multi-Amp Speaker System

The CS-A500 incorporates an FB (special Paper) 10" cone woofer, a $-3/4" mid-range and 3" tweeter in an infinite baffle enclosure-reproduction is exceptionally clear. It is also provided with inputs for use in a multi-amp system as well as full-range speaker system use. An easy operation level control for mid range and highs is on the walnut front baffle. The cabinet itself, of lustrous walnut, adds a gracious touch to any interior.

 

Speakers

Here is a smooth and powerful speaker system with woofer, mid-range speaker and cone tweeter this combination provides wide frequency response, clean sound, better directivity and transient response.

FB Cone Paper

For particularly fine separation of highs and lows, and improved efficiency, the paper of the speaker cones is manufactured with Pioneer's newly developed "Free Beating" process. Specially selected plant and animal fibres are combined to create a cone paper that ensures lower distortion and higher efficiency.

Level Control

The CS-A500 has a level control for mid-range and high frequencies, to allow acoustic adjustment to your particular room. There are 3 positions: - Increase, - Normal, - Decrease, with a 2 dB difference between steps. This control is on the front baffle, and the grille frame can be removed without tools for easy operation.

Multi-Amp Inputs

In addition to the full-range speaker system inputs, the CS-A500 is provided with inputs for operation in a multi-amp speaker system. You can use your present electronic crossover network, or for best result. Pioneer's electronic crossover network Model SF-700, preamplifier Model S.C.-700 and main amplifier Model SM-700. you have a choice of either a 2-channel or 3-channel multi-amp system with the selector switch on the back of the enclosure.

Crossover Network

One of the most important parts of any 3-way speaker system is the crossover network. To ensure high performance here, the CS-A500 employs the finest quality coil and ferrite core for excellent transient response. And the crossover points are set at lower frequencies for lower distortion and superior directivity. The damping is excellent and it is free from Intermodulation Distortion.

Cabinet

The CS-A500 cabinet is an infinite baffle, bookshelf type of oil-finished walnut - it blends in beautifully with existing decor. Oil-finished walnut is also used for the front baffle, to preserve the handsome appearance even when the grille frame is removed.

McIntosh XL10 loudspeakers

The XL10 is a three way loudspeaker system with two active drives and one passive. It can accurately reproduce a three dimensional sound space with smooth response. The McIntosh anechoic chamber provided the ability to adjust response, amplitude and arrival time. As a result, the XL10 can recreate stereo sound for you with full depth and spaciousness.

The XL10 has a one inch dome tweeter, a carefully matched, high power handling eight inch woofer and a ten inch controlled mass passive radiator. It has an extensive and meticulously designed crossover network.

The eight inch woofer has a copper wire voice coil wound on a black anodized aluminum voice coil form. This form, radiates heat effectively. Excessive heat is always destructive to electronic circuit elements so this design feature is very important to the long life of the XL10. the windings are attached with a high temperature, thermal setting adhesive.

The voice coil assembly is joined directly to the rigid cone. It moves in the magnetic field of a critically sized magnet and magnet structure. This assembly is cantered and suspended in the magnetic field by a special cloth spider. The compliance of the spider is controlled by the careful impregnation of the cloth with phenolic resins. Diligent engineering, decades of experience and continuous testing determined the selection of the right mass of the cone assembly to ideally match the energy capability of the magnetic structure. The total of the cone, voice coil, and suspension assembly is attached to the speaker basket with a critically formed, closed cell urethane surround.

The inch passive radiator has an accurately adjusted moving mass and compliance which complements the design characteristics of the eight inch woofer and the volume of air in the Xl10 enclosure. In the lower bass frequency range, this rigid cone is driven in phase, acoustically, by the woofer, extending the system acoustic output. The cone assembly is attached to the speaker basket by a special cloth spider and a closed cell surround.

The one inch high frequency dome tweeter is made of a specially formulated textile which is driven by a copper wire voice coil wound on a high temperature voice coil form. The assembly is centered and suspended in the magnetic field by a special surround. Both dome and surround are coated with a proprietary material to make an air tight seal. The surround is connected to an intermediate ring which is fastened to the magnet assembly.

The frequency directing crossover network directs all musical information below a designed frequency to the woofer and all frequencies above to the dome tweeter. The McIntosh crossover network, however, has additional tasks to perform. It must smooth the response in the active area of sound. A loudspeaker that can deliver ideal depth, spaciousness and three dimensional sound space, requires a crossover network that is a product of particular and comprehensive examination of the multitude of mathematical potentials to include the exact circuit components in order to provide smoothest response and correct arrival time. Exhaustive measurements in the McIntosh Full Sized Anechoic Chamber assures the exactness of the circuit and of the components selected for the crossover.

Thiel CS1.6 loudspeakers

Coherent Source ® Loudspeaker

 

The CS1.6 is a 2-way floor-standing model incorporating several new innovative design techniques that greatly improve performance in a small, floorstanding loudspeaker. The 36-inch tall CS1.6 delivers a much purer and more open upper midrange response coupled with a sweeter and smoother high frequency performance than conventional two-way models. The new CS1.6 also offers a very high 90 dB efficiency to work well with lower amounts of amplifier power.

Completely Time and Phase Coherent

As with all THIEL loudspeakers, the CS1.6 is completely time and phase coherent for much greater sonic realism. THIEL’s Coherent Source® technology achieves the elimination of both time and phase distortions that cause alterations in the reproduced musical waveforms of most loudspeakers. Eliminating these distortions results in enhanced realism, clarity, transparency and immediacy as well as improved imaging and soundstaging in both the lateral and depth perspectives. Phase coherence is achieved by utilizing a sophisticated first-order electrical crossover system in conjunction with unusually wide bandwidth drivers. Time coherence is achieved by placement of the drivers on a baffle that is sloped at the correct angle to cause the sound energy from each to reach the listener at the same time.

 

Innovative Woofer and Tweeter Design

Much of the CS1.6’s outstanding performance is the result of its new high output, high efficiency aluminum dome, 1-inch tweeter and the innovative woofer diaphragm/voice coil design. Both drivers incorporate short coil/long gap, copper stabilized motor systems to greatly reduce distortion, employ metal diaphragms for very uniform Frequency response and clarity, and use Long Excursion Motor Systems for high Output capability.

 


High performance from a small, floor-standing loudspeaker

The CS1.6 is a two-way, floor-standing speaker system that incorporates THIEL’s latest innovative driver technology, rugged cabinet construction, and phase/time correct Coherent Source® design. Allmetal diaphragm, low-distortion drivers are used for outstanding tonal response and the advanced phase correct crossover design greatly improves spatial fidelity and clarity.

The CS1.6 tweeter is a high output, high efficiency aluminum dome unit with long excursion abilities that reduce distortion and increase output capability. The new high frequency driver uses a short coil/long gap motor system design for low distortion, a copper sleeve to stabilize the strength of the magnetic field for reduced distortion, and practically unbreakable lead wires for increased reliability—features all shared with THIEL’s more expensive models’ tweeters.

 

Metal diaphragm, low distortion woofer

The CS1.6’s 6.5-inch woofer uses a much larger than normal diameter voice coil to greatly extend the woofer’s bandwidth for improved upper midrange performance. The large diameter coil distributes its driving force over a large area of the cone rather than concentrating it at the center. This coil design coupled with the woofer’s metal diaphragm increases the cone’s stiffness and frequency of unwanted resonances for very clear and open reproduction. The short coil/long gap, copper-stabilized motor system dramatically reduces distortion. Equally innovative is the woofer’s centrally located neodymium magnet that is placed inside the coil, rather than outside, creating an inherently shielded speaker to prevent picture distortion when placed near video displays.

 

Cabinet construction

The compact cabinet is built with a 2-inch thick front baffle and 1-inch thick cabinet walls for extreme rigidity to reduce unwanted vibration, improving clarity and spatial performance. The baffle’s rounded edges reduce diffraction effects for improved tonal, spatial, and transient performance, and its sloped front correctly time aligns the tweeter with the woofer. The unique slotted bass reflex system reduces unwanted port noise and grille loading effects.

 

Finished in the world’s finest woods

The CS1.6 is available in a wide variety of exquisite, real-wood, laminate, and painted cabinet finishes, finely crafted to enhance any home environment.

Mission 717 loudspeakers

Different designers emphasize different aspects of the speaker characteristics. For example, some speakers offer high efficiency to the detriment of accuracy; others produce smoothness and low coloration but fail to generate adequate sound levels and musical dynamics; many impress on initial listening, but in the long-term produce fatigue and become irritating. At Mission we try not to compromise, and have optimized our designs within the limitations of the current state of technology. The result is a range of loudspeakers capable of reproduction of all forms of sounds accurately with very low distortion, excellent efficiency, and with high power handling potential. The speakers themselves are neutral in that they have no characteristic tonality. They reproduce all types of musical program with maximum fidelity to the original material. Above all, they are capable of attaining without distortion, sound levels with the realism of any live concert.

 

The 717 is a brand new addition to the Mission range. Here, the greatest challenge to our design team was to ensure a significant advance over the 700, which has presented genuine competition to many models costing substantially more.

Mission 717's will now set a completely new standard of quality in their price category and will be one of our most formidable products for the 1980s.

The 717's advanced 210 mm drive unit features a plastiflex treated cone material which is radially reinforced to achieve a combination of lightness, rigidity and sonic opaqueness. The 25 mm soft dome HF unit offers smooth treble response and excellent dispersion.

This high performance system offers a rare combination of accuracy, low coloration, high dynamic range, high efficiency and high power handling. Above all, loudspeakers of this quality will only be fully appreciated after extensive listening tests using a wide variety of musical material. Only then will the discerning listener experience the astonishing realism and depth offered by today's technology at its best.
