I have a Klipsch 5.1 Promedia system which has been great for 12 years but now the electronics are no longer working. I have an old Yamaha receiver that I hooked up to the 5 speakers and that works fine. Now I would like to repurpose the subwoofer by removing the Promedia electronics and installing a new amplifier and make it into a working powered subwoofer.


Inside the subwoofer cabinet there are two bass speakers wired in parallel. Can anyone recommend an amplifier module or kit that will power these speakers. I could then plug this subwoofer into the subwoofer port on my receiver and have a working system. I would prefer this solution to buying a new subwoofer.

Honestly for the money you will need to spend to buy a plate amp, and then retrofit it to the sub, you could just buy something like the Dayton SUB-1200 and outperform it. The price will probably end up being very similar, and you come away with better bass.


The DIY sub-forum would be a better place to get some advice on how well this might work.

You could contact Klipsch and see how much a replacement amplifier module would cost for an RW-12 or similar, and then install it.

You may be able to find some BASH amps on ebay relatively cheap, but I would go with the first poster and just go with a whole new setup. The sub you have is probably mediocre and for the price to replace you may be able to upgrade for close to the same price.

Thanks for the responses. Klipsch no longer services this unit and I have read mixed reviews about third party repair service so I decided not to have it fixed. I purchased a used Yamaha receiver on eBay and it drives the 5 speakers very nicely. Now all I need is a subwoofer. I looked at the Dayton SUB-1200 and it looks like a great choice based on the reviews. Thanks for the recommendation. I have one question about the Dayton. Looking at the on-line images I see that it has left and right inputs but my receiver has only one subwoofer output. How would I connect the two.

The Dayton manual will tell you the preferred way, but generally the left input acts as the LFE input, or some manufacturers recommend using a Y-splitter at the sub.
