Home Speaker Asylum

General speaker questions for audio and home theater.

RE: Riddle me this!

I used to own a pair of cary/montana 301 loudspeakers. From day one I noticed that one loudspeaker sounded (louder and warmer) different from the other. There were 3 drive units in each, and with a simple battery test I was able to discover that one of the drive units had been wired out of phase.

Place a 1.5 volt battery across the terminals of each drive unit in turn, place + to +. The speaker cone should move out if in phase.

Do not used this test on a compression drive unit.



Regards,
Mike
