I need to take a closer look at the sub but it appears to have stopped working. In my initial research it appears that it is something that happens fairly often. A couple of questions...
1-I would like to keep the sub original as the L212/B212 I have is in very nice condition. Is there a good place to send the energizer to have it repaired?
2-On the other hand I have heard the amp is under powered and may be better served by something like a 150w amp vs the 75w amp in the energizer. I'm a bit torn on locating a place to repair it or taking it out and placing something like the the dayton sa230 in thee underneath cavity.

Any direction on getting it repaired or opinions on which way to go?

I use the L212 system daily in our living rooom system and am really missing the sub and need to start the process of getting it fixed.
Thanks.
