I have no time to surround the drivers. ALL SPEAKERS WORK and ARE ORIGINAL. There is a product tag from AR on the lower back panel that states the serial # on one is #EH 01774. The other speaker has no tag. 10 Speakers NEED NEW SURROUNDS (Both Tweeters are Original and excellent working condition and need nothing) + I would replace only one 8 dust cover on one of the drivers. The cones suspension works fine with no rubbing but the dust cover is dented in on just one of the 8 drivers. Original Front and Back Black Grilles Included. I just oiled the tops and bottoms rests , cleaned the cabs and grilles. The tops have some minor scratches, If you want them perfect then its and easy job to refinish the tops and bottom rests. But you have to pick them up or arrange someone to pick them up. The AR TSW 910’s pair have 12 drivers two 12″ LF , one 8″ LF-MID. Two 6.5″ mids + two 1″ titaniaum tweeter drivers.

Each The AR -Acoustic Reasearch TSW 910 These two flagship models represent the best in stereo loudspeakers. Dual woofers – one on the front and one on the rear – provide bass power down to the limits of audibility and because the woogfers are on different cabinet surfaces, room effects which can cause cancellations in the critical mid-bass region are virtually eliminated. These superior models also incorporate the most advanced dome tweeter AR has used to date. A 1 titanium dome with its own specially designed Tetra-helix mounting plate and acoustic lens produces teh most accurate harmonic structure and sense of spaciousness ever offered in an AR loudspeaker. The TSW 910 has bi-wire capability for those who wish to maximize the performance of thier sound system. Even tweeter mounting plates can degrade the sound if they have a regular shape. In the TSW Series we have avoided this problem by emploing a special computer designed tweeter face plate called a Tetra-helix. The Tetra-helix is shaped to broadly distribute and minimize any re-radiation so that no single frequency is affected by edge diffraction. The result is a much smoother response and more natural treble. Polypropylene is an ideal cone material and offers unrivalled sonic naturalness and reliable production consistency. In the TSW Series our twelve, ten, eight and six inch woofers and six inch midrange have all been designed for excellence. The woofers generate clean, deep natural bass, while the midrange unit has controlled dispersion for optimum stereo imagery Acoustic Suspension Acoustic Suspension is a system invented by Acoustic Research which makes deep clean bass possible from enclosures of all sizs. Its revealing naturalness is ideal for compact disc and analog alike. Indeed, it could be said that Acoustic Suspension has now fully come into its own with digital recording. The item “Rare Pr.
