INTRODUCTION:
The FRX drivers are designed for open baffle applications employing low power amplifiers. The
driver is 8 inches and has a full range response.
They are hand made and therefore very limited production drivers with superb frequency
balance that has been made possible by electromotive coupling. Electromotive coupling is a
magnetic circuit that has been tuned to offer spectacular performance within a narrow power
window. Put another way, these speakers are not meant to reach party listening levels, instead
they were designed for intimate listening at sane volumes. Exceeding this volume restriction
will result in completely harmless, but nonetheless objectionable, distortion. You'll quickly
know when you are over driving them because they'll tell you. The distortion is in the magnetic
circuit itself, not the physical speaker. We designed the magnetic circuit to handle about 7
watts, whereas the physical speaker can handle 30 watts. Naturally if you use an OTL or Solid
State amplifier that faults and puts DC voltage on the speaker, it will fry the FRX without
hesitation just at it would any speaker.

INSTALLATION

The FRX driver can be installed at any angle without effecting performance. The binding posts
on the rear of the driver accept up to 8 AWG wire, SPADES or BANANA jacks. In open baffle
applications is it recommended to hook your speaker cables directly to these binding posts.
AMPLIFICATION
The ideal amplifier for these drivers is a 6 watt per channel TRIODE amp with no negative
feedback. The perfect amplifier is our Zen Torii push pull amplifier because it adds substantial
weight to the lower frequencies, and has an adjustable treble control so you can flatten out the
highs in any room.
ENCLOSURE
The perfect enclosure for these drivers is the DECWARE Zen Open Baffle (ZOB) of which plans
are available on the web site, www.decware.com. A picture of the ZOB enclosure design is
shown in the back of this manual.
