@erik_squires Good point! Looking closely, it is vibrating like it's normal twin, but it also is moving very slowly in and out, about a half inch. Yes it's making bass. It sounds just like its twin. Bear in mind this has only happened twice in a year.

@atmasphere Good advice! I am supposed to be getting a new CD player tomorrow that I ordered a month ago. I will be going through all the suggestions. Thank you. |
Second the motion on switching speaker cables and seeing if the pumping motion moves over to the other speaker. If that happens, then the source is the problem. I have a few recordings that do have subsonics. One in particular is a CPE Bach recording in which the orchestra and audience were apparently on a wooden stage or platform along with the microphones and you can hear the subsonic rumble from people moving around. That's just one example. Another cause of this in the old days was from warped LP records, or turntables that were poorly isolated. The pumping motion of the woofers was very obvious. |
@erik_squires The woofer is just a slave... Doh! I should have known that. Good point. Even more embarrassing, I've been involved with this hobby since 1975...🙄 |
@mlsstl Good Point! Will listen to the two songs that it happened on again... |
