Question about KLH ASW12-200 Subwoofer
Please help. When plugged in the power cord, I saw green light on, but my KLH subwoofer has no base sound, just regular sound. I tested the speaker unit (the cone) and it is in good working condition. How to test the amp unit in the back to see what's wrong ? I did open it and touch the big black block and assume it should be warm with power on, but it wasn't. Could it be blowned ? and is ot easy to change it? Thanks in advance. Keivin
I dont get bas anymore. i hook up and get a hum type of noise. when i hook up at speaker level. it works, but it contains vice also.
