AR 303a
More than
fourty years of research and design have led to the production of this
extraordinary musical component. The natural evolution of the classic 1967 AR
3aand the critically acclaimed 1994 AR 303, the new AR 303a is the pinnacle of
the Acoustic Research loudspeaker line, combining reference quality sonic
performance and furniture grade appearance.
The AR 303a
Loudspeaker System is finished in a genuine rosewood veneer, accented by a
unique gold logo and serial number plate. It features a redesigned creossover
network, heavy duty 14 AWG internak wiring and bi-wire/bi-amp capability with
improved gold plated 5-way binding posts.
True
Acoustic Suspension technology
The AR 303a
is based on Tre Acoustic Suspension design, a technology invebted by AR in
1954. a true Acoustic Suspension design uses the air inside of sealed enclosure
to precisely control the excursion (back and forth movement) of the woofer
cone.
The woofer
cone is made of rigid felted paper, and when combined with a high compliance
surround it moves like a piston. The long-throw voice coil is designed to
undergo large disolscement while maintaining linearity. The compression annd
expansion of air in the enclosure provides the linear restoring force to the
cone. A True Acoustic Suspension design results in tight, controlled bass,
excellent power handling capability and low distortion even at high output
levels.
