1. IB ARCHITECTURAL ACOUSTICS AIA SERIES Acoustical Components High Performance Woofers Architectural Acoustics now offers to the sound contracting industry a line of premium grade low frequen cy loudspeakers These state of the art woofers feature the combination of a Keviar impregnated cone and a highly refined magnet struc ture to provide outstanding efficien cy reliability and performance The Kevlar impregnated cone is stiffer than an equivalent weight paper cone reducing the tendency of the cone to distort the shape of the voice coil thus avoiding rubs and scrapes Superior power handling results from the increased stiffness especially with large violent cone excursions This cone also offers lower distortion than a paper cone due to a greater dampening of un wanted cone vibrations The piston action of the Kevlar impregnated cone is extended to a higher fre quency while the range above is better controlled with a reduction in vibrational break up The magnet structure of the new woofers has been engineered with an advanced geometry pole piece providing both higher power handl ing and lower distortion than more conventional structures Our ex clusive one piece die cast back plate pole piece eliminates an undesirable air gap in the magnetic circuit enhancing efficien cy and reliability In the unlikely event of the failure of a loudspeaker the cone basket assembly is field repla2.
