Hey gang.. keeping my fingers crossed someone can provide some advice for me..
Today I received a Cerwin Vega CLSC-15S and added it into my HT system...
And that's when the problems began. Initially I had serious 'hum' whenever the sub was turned on and the volume brought up to a level beyond 'zero'. This would possibly indicate a ground-loop issue... so I tried a different wall outlet which _greatly_ reduced, although not completely, the hum. A RCA-style ground-loop isolator would also address the issue if I had one on hand..
The input to the sub comes for my Sony STR-DE885 receiver's sub-out.
This worked out great for just beyond an hour of _moderate_ use of DVD and CD listening.. at which point the Cerwin-Vega sub expelled a loud "boom/pop" and produced no sound.
Thinking that the over-heating protection built into the sub had kicked in, or the fuse had blown, I turned the sub off and let her sit for awhile (and confirmed the fuse was dandy).
Upon turning the sub back on, a large "pop"* is heard, followed non-stop by a loud continuous humming sound (not like a ground-loop hum, but the kind of hum you hear when standing next to a transformer sub-station or hydroelectric generator).
* the 'pop' is not like your regular 'pop' you sometimes here when turning on/off a sub... this is more of a "popping a paper bag/ping-pong ball" pop.
..so.. here I am.. heartbroken and dismayed.. at the oh-so-brief 1-1.5 hrs of enjoyment from my Cerwin-Vega CLSC-15S sub.. wondering.. what happened.. and what can I do next?
