New levels of performance in direct radiating speakers are achieved by the ACOUSTICOUPLE design concept and SYNCOM speaker testing. Each INTERAUDIO speaker is designed with the objective of providing the best overall music reproduction at its price. After reviewing the features and benefits of the various models, we invite you to audition the INTERAUDIO speakers of your choice, siele by side with conventional speakers in the same price range, and judge whether this objective has been met.
INTERAUDIO speakers may be used with amplifiers having output ratings consistent with the power handling capacity and impedance of each model identified in the technical data presented. lt should be noted, however, that normal listening levels require less than 20 watts with these speakers.
Contemporary in design, all INTERAUDI 0 speaker cabinets are of rugged construction with walnut grained vinyl veneer and color coordinated grill cloths.
