Re: Slightly OT: Channel phase
>>Take a 1.5 AA cell and two connecting leads; connect the + and - of the cell to the loudspeaker terminals; you'll hear a small "pop" and the bass driver will move slightly, either forward or backward. The drivers of both speakers should move in the same direction when the polarities are matched.
This is the procedure I've use many times, to check speakers. I usually
find a 9V battery works better though.
>>Ithink only relative phase between the two speakers matters, i.e. if you reverse polarity in both speakers that shouldn't mater.
>>Again, I would stress that I won't be held responsable if you damage
>>your speakers trying this...
Ditto on what Pedro's said though.
