I purchased a pair of rtr tower speakers recently. I didn't listen to them before refoaming. I checked the continuity on the woofers before and they were fine. Once I got the woofers back into the cabinet and fired up they sounded dull and eventually tripped the resettable breaker. Pushed the button and they fired back up. Left them playing on low volume and they started to wake up. Same thing happened with the other tower as well. Is this normal? Just the electrons flowing through an old, dry cap..? Should I be worried? Is this normal with old speakers that haven't been played in a long time? I realize that a recap would be a good idea anyways at this age.
