Focal Chorus 806V speakers

For Focal, Chorus symbolizes one of the most stimulating challenges for the loudspeaker and refined product manufacturer that we are: to allow the greatest number of consumers to access our technological innovations. For the first two generations Chorus (2000) and Chorus S (2003), the objective was to conserve a hi-end sound and maintain sophisticated Focal technologies by adapting our industrial machine to the highest standards. While outsourcing had become a key economic strategy for the majority of manufacturers, we chose on the contrary to heavily invest in our manufacturing process in order to achieve an exceptional sound quality while at the same time remaining competitive. It is the only possible way in this path of permanent innovation: development and manufacturing of loudspeakers ”Made in France”, design by cabinet-makers, mastery of quality, total autonomy in the design and development of our products. This strategy has been key to the success of the preceding Chorus lines.

This third generation known as Chorus 800 V will go even further in this strategy. Technological innovation does not only solely touch strategic components of the speaker, but the actual whole of the design. Thanks to the use of advanced and exclusive materials, elaborate manufacturing techniques of the cabinets, the Chorus 800 V line of today shines with a unique, hi-end esthetic. Chorus V isn’t only a performing product line, ideal for entering the Focal universe, but objects that will inhabit living spaces, with an innovative esthetic, quality of manufacture and a finish worthy of a higher segment. This is indeed a new esthetic dimension, a new era for the ”Spirit of Sound”.

 

Neutral and balanced, the Chorus 806 V seduces by the richness of its upper midrange and the speed of its bass. An entirely refined speaker, ideal to play in rooms under 20 m2 without any limits. And easily larger spaces if it is combined with SW 800 V.

Focal Chorus 705V speakers

Since the year 2000, the different generations of the Chorus line have benefited from this approach, as we produced speakers that cost less and performed better. To achieve this goal, we invested massively in a superior method to speaker manufacturing, where intelligent machining and precise handwork were absolutely necessary.

It was the only possible way in this drive for quality and competitiveness: development and manufacturing of French-made loudspeakers, design of the cabinets, quality control, a total autonomy in the development and design of our own products. This method allows us to innovate, to entirely and independently turn ideas into reality, to place patents internationally, and have the means to anticipate trends. And finally, to progress.

The third generation, Chorus 700 V, goes even further. A direct descendant of the Chorus 800 V line of which it heavily borrows technical elements (except Power flow) yet with a more Amati traditional finish, Chorus 700 V invites you in to the Focal universe. The build quality and high-end finishing work are entirely unknown in this price-range.

 

Chorus 705 V is the ideal loudspeaker for installation in rooms of modest dimensions (approximately 15 m²). With a responsive and lively bass, it represents the foundations of a great system, especially when paired with the SW 700 V subwoofer.

Castle Harlech speakers

Rather than sacrifice the superb stereo imaging that result from a narrow cabinet, Castle has employed two small polypropylene coned mid/bass drive units in the Harlech -  on the top and one on the front face - instead of a larger mid/bass drive unit.

Each driver works with its own Quarter Wave pipe tuned to different frequencies but which join in a common vent at the speaker's base. The two drive units give exceptional bass extension and superior control but also radiate midrange energy into the room in a way that produces a large, spacious sound with very low distortion.

 

Quarter Wave

Competing speaker systems set themselves apart by the techniques with which bass extension is achieved. For the largest models in its range of floor-standing speakers Castle has adopted Quarter Wave loading. This technique can be traced back to the work of the legendary Paul Voigt inn the 1930s and has more in common with vibrating columns of air in organ pipes and folded horns that with alternative methods of bass extension like reflex or transmission line loading.

Designer Roger Loughton's execution of Quarter Wave techniques for Castle uses the latest measurement and optimisation techniques. The open, natural quality of attuned pipe has been retained in a tapered version that, with the drive unit at an optimum position along the pipe, reduces unwanted excitation at the fundamental frequency of the pipe and associated harmonics by natural acoustic filtering. Tapering the pipe also allows it to be folded inside the cabinet that not only brings it down to domestic size but enables the internal structure considerably to add to the rigidity of the enclosure.

The superiority of the Quarter Wave technique, correctly executed, over orthodox reflex loading with a cabinet of the same or bigger size is higher bass efficiency, maintained down to a lower frequency. Quarter Wave systems have the natural power and character of true, deep bass.

Castle Howard S2 speakers

The Howard S2 is the largest member of the Castle Quarter Wave family. The narrow fronted cabinet coupled with a 25 mm metal dome tweeter guarantees stable stereo imagery with excellent presentation of depth and separation

The two 165 mm plasticised paper pulp drivers were developed especially for the Howard. They have massive high energy magnets, stiffer than usual suspensions and are built into substantial die-cast chassis.

These drive units excite the tapered and folded Quarter ave pipe inside the rigid cabinet. Exceptionally clean, extended bass with low distortion, high energy mid and sweet treble are the hallmarks of the Howard S2.

 

Our largest Quarter Wave system loudspeaker, the Castle Howard S2, is tuned to roll of below 35 Hz, making the system larger than the Harlech, and requiring an extra bass driver to load its longer horn and increased internal volume. Thanks to the high efficiency inherent in Quarter Wave systems, the increased cabinet volume also produces increased sound volume which remain slow in distortion and high in accuracy, the two key parameters for true high fidelity sound. Higher register are delicately handled by our proven 25 mm metal dome treble unit. As beautiful to look at as it is to listen to, the new Castle Howard S2 is engineered for a lifetime's enjoyment.

 

The room filling spaciousness in the Howard S2's sound is aided by careful positioning of the bass/mid drivers on both the front and top surfaces of the cabinet, so you can enjoy more of the music, in more locations within the room.

Apogee Acoustics Centaur Minor loudspeakers

The Centaur Minor was Apogee's first and smallest ribbon hybrid when it was released in 1991. Also the cheapest yet Apogee at £1150 in the UK, and a similar price in $'s in the US.

At 100 cm tall, 35 cm wide and 22 cm deep, its footprint is no bigger than a stand mounted mini-monitor speaker.

The 26" (6 element) etched ribbon tweeter is the same version which is used in the later model of the Stage. The 6.5" dynamic cone woofer is in a long rectangular enclosure set towards the outside of the speaker so the dipole ribbon fires into 'free air'. It is positioned at a height which is the mid-point of the ribbon tweeter, it can just be seen behind the (hard to remove) grill.

Apogee Acoustics Centaur Major loudspeakers

The Centaur range was the first hybrid speakers range from Apogee, the Centaur Major being biggest model.

Using a 10" dynamic woofer and a 40" ribbon tweeter the Major stands 163cm tall, 46cm wide and a total depth of 30cm.

The enclosure for the woofer is approximately 107cm high, 28cm wide and deep. The tweeter ribbons are on the inside edge of each speaker and like all Apogee's work as a dipole.

The speakers are nearly as room dominating as the Duetta Signatures, with only the width being significantly smaller, and require nearly as much free space around them.

Although they will work with smaller amps, they justify being fed by a high quality, high current amp.

Key Selling Feature: APM Drivers

The wide dynamic range, flat frequency response, and low distortion of digital sound sources have forced audio designers to rethink the basic principles of cone shaped speaker construction. The APM-707 is a product of that reexamination. Sony 's APM speakers compensate for the coloration created by the "cavity effect" - which is caused by the cone shape design of traditional speakers. The "cavity effect" is created by a mid-air collision of sound immediately above the opposing surfaces of the speaker cone. APM drivers are flat - so the "cavity effect" is automatically eliminated. Most traditional cone shaped drivers are also made of paper which is not rigid enough to handle the peaks created by highly dynamic program material. Sony conquers this problem by using an aluminum honeycomb material, which is powered at exactly the right points to eliminate distortion. All these factors create a speaker which is ideal for digital audio - but which will improve the sound of any source.

 

Key Demonstration

Anyone in the market for an excellent speaker is a good prospect for the APM-707 - but customers who have purchased a Compact Disc player or a beta Hi-FI Betamax are already particularly well qualified. Start your demonstration with a brief audition. Demo the APM-707 with Sony Compact Disc Player and wide dynamic range digital material which your customer knows well. When musical peaks arrive, make sure to point out that the speakers are designed to reproduce just these type of passages. Emphasize the clarity of the sound. Then, take off the grille cover. Point out the APM drivers and the resilient honeycomb construction to your customer. Conclude your demonstration by continuing the audition with another piece of digital program material. As your customer

 listens, point out the deep, rich bass produced by the Accurate Bass Radiator; the wide dynamic range, and the low distortion

Tannoy Dover loudspeakers

Dual Concentric Time Compensated Loudspeaker System

The famous Tannoy Dual Concentric in a modestly sized cabinet that can be floor standing on its own plinth, mounted on speaker stands or a bookshelf.

A 10-inch (254 mm) version of the Dual Concentric drive unit is used in an infinite baffle (unported) cabinet, with rigid bracing and graded acoustic foam damping, to give the best possible sound reproduction in a loudspeaker of this size.

Each Dover is supplied with a separate plinth. If used as a floor standing loudspeaker this plinth can be attached to the base of the cabinet with the screws provided. When used on stands or shelves this plinth is not required.

The Dover is designed to provide the high quality sound of the Tannoy Dual Concentric system in a size of loudspeaker to suit smaller listening rooms.

The high quality of sound reproduction is matched by the standard of cabinet construction. Every Dover is finished in genuine walnut veneers, oiled by hand and the baffle is covered in real cork.

 

The Tannoy Dual Concentric is, therefore, a true single point sound source loudspeaker system which eliminates unnatural time delay, and provides the smooth consistent intensity of sound necessary to create a precise stereo image.

Tannoy Mercury MkII speakers

The Mercury MkII loudspeakers share the advantage of high power handling and sensitivity with low distortion and smooth frequency response - qualities which have ben the hallmark of Tannoy high fidelity loudspeaker systems for many years.

 

 Loudspeaker Enclosures

To provide optimum performance a loudspeaker cabinet must be rigidly constructed and acoustically treated. The Mercury MkII is constructed from high density particle board lined with an acoustic material to absorb internal reflections and eliminate standing waves. The cabinet is internally braced at antinodal points to minimise cabinet resonance and colouration and the narrow front profile ensures good horizontal dispersion. Low frequency loading of the system is provided by a carefully designed ducted port which reduces distortion and extends the bass response. Each loudspeaker is fitted with a detachable grille of acoustically transparent cloth stretched over a wooden frame.

 

 Drive Units

High frequencies are produced by a polyamide dome treble unit which combines a very smooth response with low distortion and wide dispersion and gives a finely detailed sound. A magnetic cooling Ferrofluid is incorporated and combines high power handling capacity with reliability and protection against sudden overload transients. The asymmetrical front plate is sculptured to improve reproduction by reducing diffraction effects.

Low and midrange frequencies are reproduced by a 200 mm polyolefin cone unit. This cone material gives a very smooth frequency response with negligible colouration. A newly developed cone/coil apex configuration provides a very rigid construction at the point where the cone is driven by the 4 layer high temperature voice coil.

 

Crossover Network

The crossover network receivers the electronical signal containing the fill frequency spectrum from the amplifier and divides it between the bass/midrange unit and the soft dome treble unit. We use only high quality components, including low loss solid dielectric capacitors and generously rated resistors and inductors. All components are hard wired and internal wiring is by heavy duty cable to minimise signal loss. All components are securely mounted to ensure maximum reliability and freedom from resonance.

 

Amplifier Power

In our loudspeaker specifications we recommend a suitable range of amplifier powers. The peak power handling capability of all Tannoy Loudspeakers will allow higher amplifier powers to be used with wide dynamic range material. Care must be taken with all amplifiers, irrespective of power output, to avoid abnormal conditions such as switch on surges or amplifier overloading (clipping and distortion) which may result in peaks of power greatly in excess of the specified ratings, and possible subsequent damage to the loudspeaker.
