Hi everyone, I hate to admit it, but my first post on this forum has to do with a problem. I have an RW-10 that is being fed LFE from a Marantz SR7500 receiver, and a few months ago, I noticed that it started barely working. It used to absolutely decimate our little apartment without much effort, and I had it set up to match my other speakers perfectly, even with stereo music. I only ever had the sub volume on the receiver set to +5 (it goes upto +10, but the receiver calibrated it for the room at +5), and I only ever had the gain/volume control on the side of the sub itself at about 50%.
I already talked to Klipsch customer service, and we've established that the driver itself isn't toast, and that the unit still powers up. When I first bought the sub (it was a floor model that had hardly ever been used in the shop I bought it from), I used only the LFE jack on the back of the sub, but that stopped working properly about 1 month after I got it, and I switched to using the left/right input jacks with the supplied Y cable for my monster subwoofer cable. This last configuration worked fine for over 18 months, but about 2-3 months ago the subwoofer has started outputting very little volume. Even with the receiver set to +10, and the gain on the rub at 100%. Put it this way, the 5 1/4" subwoofer from my Harman Kardon Champagne 2.1 Computer speaker kit puts out more bass right now.
I've taken all of the tips apart on my monster cables and checked the solder joints which are fine. I've checked, double checked, and triple checked all of the settings on my receiver, and on my DVD player. There's nothing wrong with them either. The folks at Klipsch had told me that it's more likely the BASH amp has failed, than the LFE out on my receiver failing. This was after I told them I plugged an MP3 player and other sources straight into the sub, and it didn't do much with them either.
Does anyone here know what one of the amp modules would cost (talking Canadian money, not the greenback), and how easy it is to change out yourself? I've heard they are easy, and not as expensive as replacing the entire sub.
Any advice would be greatly appreciated!
