Hello everyone,
I have an old Klipsch ProMedia 4.1 computer speaker sound system. The specs are 4x60 watts and 1x160 watts for the sub-woofer.
It's starting to head south. When I initially turn it on, I hear a LOT of crackling from the speakers until the system warms up. One day, it’s going to go out on me completely.
I've done some research and learned that the problem with this system is; that over time some of the solder joints begin to fail. Finding the offending bad solder joint is like finding a "needle in a haystack." I’m guessing that it’s a result of the expansion/contraction they experience when the system is turned on/off.
So, because I absolutely LOVE the sound of these efficient little speakers/sub-woofer, I'd like to be able to continue to make use of them and Klipsch doesn’t make them anymore.
Could I get a couple of inexpensive digital 2.1 channel amplifier boards (one for the front speakers and sub-woofer and a second for the rear speakers)?
There are two outputs from the computer, one for the front speakers and a second for the rear speakers and I use the computer to control the system so I don’t need the control knobs that are part of the current system. I’ll just power it on when I turn on the computer. I never use the computer without having the speakers on.
My questions are (if this is possible):
1. What digital 2.1 channel amplifier boards should I use?
2. What power supply would be best?
3. Do I need a speaker delay protection board(s)? I want to protect the speakers.
4. What other considerations am I missing?
Thank you,
Barney
