any other noises. If any unusual noises are heard, remove woofer and test.

Driver Function

1) Remove woofer from cabinet; and - wire clips.

2) Check DC resistance of woofer; it should be

3.6 ohms

±10%

3) Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier

fed by a signal generator. Turn on generator and adjust so that speaker level output is

5.0

V.

4) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
