I was moving my speakers with the cables disconnected; going from a single wire cable to a bi-wire.  Not thinking there is any reason to be careful removing the jumpers I bridged the +/- on the speaker terminal and heard a pop.  My questions are: is it odd for a crossover to store that much energy, and do I risk damage?  (maybe this is more appropriate for 'The Starting Block -- not sure)  Thanks.

what model of speaker and which terminals were shorted - high or low frequency inputs?

If there is a large value cap in series with the driver it could store enough energy for a pop for a few minutes.

Legacy Focus 20/20.  Both HF and LF terminals, I think.
I'm pretty sure it happened twice, the first time I wasn't paying attention and I didn't think it came from the speaker, it was *snap* (HF presumably).  After hearing a *whump* and realizing the second jumper I was pulling out touched both bottom terminals, I deduced that I had probably done the same with the first jumper at the HF terminals.  Neither sound was particularly loud, and both speakers sound fine, BTW.  Just wondering: is it silly to think I could cause damage this way or am I lucky no damage was seemingly caused?

I am very aware that capacitors in power amps hold a charge for awhile, but I'm a little shocked (pun intended) that it happens in crossovers.  If somebody who know more about crossovers is not surprised then I'm happy.

Crossover caps are usually smaller values (1-10uf or so) than power supply (40uf+) but can still store enough to cause a pop.  If the speaker is OK I wouldn't worry about it.

cool, thanks
