Mid / Bass Driver<br />
The goal of every Motus driver design is linear frequency<br />
response, low distortion and superb tonality.<br />
After hundreds of hours of refinement each driver allows for<br />
the application of a minimal crossover to achieve your desired<br />
target response.<br />
Every Motus driver goes through a rigorous four stage quality<br />
control process to ensure that the driver in your loudspeaker<br />
represents the best Motus has to offer.<br />
The UH205PW1 is a state of the art underhung mid bass<br />
driver. It is equally at home as the woofer in a three way<br />
design or the mid bass in a two-way speaker.<br />
