Genesis APM-1 subwoofer substitute


This speaker is somewhat renowned for problems with the subwoofer amp but, even so, I am interested in purchasing a pair. Because it appears to be a major problem/expense to find someone to repair them I'm looking for an alternative approach to this repair challenge.

I'm not able to locate a manual so don't have a way to evaluate the circuitry and am wondering if it makes any sense to disconnect the subwoofer circuitry on both speakers and use a single stand alone sub powered directly from the stereo amplifier. Another alternative to this potentially ill conceived approach would be to use a powered sub to each speaker. The challenge here would be to somehow find a way to feed them using the crossover circuitry in the existing speakers.

Also, these speakers have what appears to to be a involved set of controls that probably rely on all of the circuitry to be in place. Again, though, the lack of access to manuals complicates the challenge.

This issue appears to be somewhat common and these speakers are worth spending time and effort on their repair so I'm hoping there is someone out there with some advice that would either help with a fix or keep me from getting in over my head.

patrick@cullencable.com will fix it.  if he can't, he'll find you someone who can.  just be patient. it may take a few days before he gets back to you with a quote.

good luck.

Soon I will be working on a pair of apm-1 for a friend since they have made advancements in subwoofer plate amplifiers I will buy a pair of those to replace failed I would also outboard the plate amps so as to leave the stock intact. I may also upgrade sub driver and will redo networks. I have found apm-1 available from $500 up so cost will be factored into upgrades and repairs. Spending $5k as one member suggest for repairs plus shipping would be crazy since values low on these and most likely will not increase. 
Hi there,

is here someone who has the service manual for the Genesis APM-1 speaker?
