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
