Key Selling Feature: APM Drivers
The wide dynamic range, flat frequency response, and low distortion of digital sound sources have forced audio designers to rethink the basic principles of cone shaped speaker construction. The APM-707 is a product of that reexamination. Sony 's APM speakers compensate for the coloration created by the "cavity effect" - which is caused by the cone shape design of traditional speakers. The "cavity effect" is created by a mid-air collision of sound immediately above the opposing surfaces of the speaker cone. APM drivers are flat - so the "cavity effect" is automatically eliminated. Most traditional cone shaped drivers are also made of paper which is not rigid enough to handle the peaks created by highly dynamic program material. Sony conquers this problem by using an aluminum honeycomb material, which is powered at exactly the right points to eliminate distortion. All these factors create a speaker which is ideal for digital audio - but which will improve the sound of any source.
Key Demonstration
Anyone in the market for an excellent speaker is a good prospect for the APM-707 - but customers who have purchased a Compact Disc player or a beta Hi-FI Betamax are already particularly well qualified. Start your demonstration with a brief audition. Demo the APM-707 with Sony Compact Disc Player and wide dynamic range digital material which your customer knows well. When musical peaks arrive, make sure to point out that the speakers are designed to reproduce just these type of passages. Emphasize the clarity of the sound. Then, take off the grille cover. Point out the APM drivers and the resilient honeycomb construction to your customer. Conclude your demonstration by continuing the audition with another piece of digital program material. As your customer
listens, point out the deep, rich bass produced by the Accurate Bass Radiator; the wide dynamic range, and the low distortion
