The TSW 910 and 810
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 cones.
The carbon-loaded polypropylene cones used in AR woofers and midranges in the TSW Series have all been designed for low coloration, natural sound and superior power handling for realistic dynamics, particularly with modern digital CD and high-quality analog source material. 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.
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
Separate inputs for woofers & upper range drivers: to accomodate bi-wiring/bi-amping
SPECIFICATIONS 910
SYSTEM TYPE: Floorstanding columnar acoustic suspension 4-way system with 5 drive-units in a vertical array with Acoustic Blanket™ for precise stereo imaging with an additional rear firing woofer to eliminste wall dip effects. Also featuring a split crossover network on the woofers and upper midranges for smooth frequency response.
DRIVE UNITS: Two 12" (300 mm) filled polypropylene cone acoustic suspension woofers - one front-firing, one rear-firing.

When you say 400 watts maximum, is that per speaker? If i bi-amp them, does the wattage of each channel need to get added to know the total watts the speaker is receiving?
ReplyDeleteThanks in advance. Total newbie here
Yes exactly
DeleteDo you have a schematic? Thank you
