Acoustic Research has been at the forefront of sound reproduction technology since our first acoustic suspension loudspeakers were hand built some many years ago. Acoustic Research, the inventors of acoustic suspension, dome tweeters and the bookshelf loudspeakers now brings you the next leap forward, the TSW Series.
Acoustic Research has combined a unique mix of thier latest developments in a loudspeaker line which offers unrivalled sound quality and value, over a wide range of price and size levels. All models except one feature AR's ¾ inch titanium dome tweter and acoustic lens for stunningly natural dynamic and widely dispersed treble. All models have an Acoustic Blanket™ to eliminate early reflections for improved stereo imagery and the largest models incorporate resonance dissipation grooves cut into the internal cabinet surfaces at critical positions to break up resonances which can spoil sound reproduction.
Polypropylene woofer and midrange cones in the TSW Series reproduce music with great naturalness. An inspired blend of high technology drive units, low resonabce cabinets and high quality crossovers has produced a line in which every model reproduces music in a refreshingly realistic way.
AR's ¾ inch titanium dome tweter reproduces highs with remarkable detail, dynamics and clarity. Its dome radiator, made from super rigid titanium, has no break-up or resonance over its working range and sounds incredibily clean, smooth and natural. Power handling is greatly enhanced bymagnetic fluid that cools and controls the tweeter voice coils for faultless reproduction of transients.
To avoid the beaming which occurs with other tweeters, we have designed an acoustic lens which disperses very high-frequencies and eliminates the unnatural boxiness which beaming can cause.
TSW's Unseen Technology
behind the attractively angled fronts, there's a lot of research and technology which you can't see - from the outside. In these cabinets is our carefully researched damping system which absorbs cabinet vibrations by means of critically positioned grooves cut into the inside of the lerger cabinet panels. Also hidden inside of the larger cabinet panels. Also hidden inside are AR's quality crossover networks designed to integrate the drive units for optimal sound quality, dispersion and stereo imagery.
The unique visual design and quality appearance of the TSW line fully reflect the technology they embody and the sound quality they reproduce. Truly the shape and sound of tomorrow - todey.
FEATURES
Acoustic Blanket™: eliminates cabinet & grill reflections that blur stereo image
Tetra-helix mounting plate: eliminates hi-frequency coloration
Extended bass response: for greater realism
Resonance dissapation grooves: reduce midrange coloration caused by cabinet resonance
Multi-way system: 6" midrange for controlled dispersion & precise imaging
Separate midrange enclosure: for less midrange coloration
Added internal bracing: further reduces cabinet resonances for clearer sound
1" Titanium dome tweeter: increases power handling
Dual woofer, front & rear: to eliminate wall dip
Quality Control
AT Acoustic Research we take quality control very serious.
Drive units are manufactured to rigid standarts for quality, consistency and reliability and are tested prior to assembly. Each crossover network uses high-grade, low tolerance components which have been carefully selected during the design process. Further testing of complete networks ensures response accuracy. We insist on using only the highest quality components throughout, ones that will maintain their performance for many years. So high are our standards, that the worldwide warranty failure rate for our loudspeakers, over a 5-year period is less than one half of one percent.
testing of complete systems against engineering references makes sure they all match the design specifications within tight limits and that is why we can quarantee that all Acoustic Research loudspeakers will continue to perform within ±1 dB of their design specifications for a period of five years.AR was the first speaker manufacturer to offer full Five Year Warranty. One more AR innovation, one of the few most other manufactures dare not copy.
