Definitive Technology UIW64A User Manual

The Ultimate In-Walls have been voiced by Definitive engineers

(using the superb facilities of the National Research Council) to the
same high-end standards as all Definitive loudspeakers. The drivers 
and baffles are perfectly integrated into the designs to minimize the 
diffraction problems that are inherent with most other in-wall 
loudspeakers. To ensure that you experience the finest performance 
possible from your Ultimate In-Walls, we encourage you to read this
owner’s manual to familiarize yourself with the proper installation 
and set-up procedures.

All models:

• Incorporate high power, high definition cast basket Definitive  

bass/midrange drivers combined with state of the art Definitive          

1" dome tweeters (except UIW 63/A and UIW 83/A which use

a stamped basket driver).

• Incorporate polypropylene cones with butyl rubber surrounds.

• Incorporate a complete precision crossover system designed by 

Definitive engineers for seamless driver blending.

and plastic paint masks.

• UIW 55, 65, and 75 incorporate a variable high frequency

different mounting positions.
