Problem with Home theater system

hey guys, I'm kind of a noob at all this audio stuff. However, I do enjoy listening to the system I have, so I was wondering if any of you guys could help me out.

I have a Sharp SD-HX500 receiver with a sony SA W3000 sub, 2 athena WS-100, 2 athena ws-60, and 1 makeshift center channel speaker in a car casing.

Just last week, pretty much all my woofers blew in EVERY speaker except sub and center. On top of that, my receiver keeps making buzzing noises ( I think out of the fan) whenever I turn it up to 75% or above volume. Now, to be honest, I did take one of the back speakers out b/c I was hearing that one of the woofers was blown. After I did that, the other woofers gradually started to go 1 by 1.

I just but 10 new woofers for over $300 so when I install them, I don't want them to go to waste. I just want to know...is there something wrong with my receiver that's making my speakers blow? each speaker handles over 100w and the receiver is 500w total.

any help would be greatly appreciated!

According to your unit's specs it only puts out 70w and the Athena 60's are rated at 150w so it shouldn't be blowing your speakers. Combined with the odd buzzing noise I'd say it's time to refer it to the proverbial "qualified service personnel".

the receiver is more than likely clipping and causing the problem:)

based on your description of the events, your amplifier is probably failing and putting out tremendously distorted sound. The massive distortion is what blew your speakers. I'm afraid it's time to consider a "real" a/v receiver to power your system. Fixing all your speakers and connecting them back to the Sharp is a death warrant.

Hi FF86.

Please do not hook up the new speakers until you have a pro check out the receiver.

Agreed, It is much easier to damage speakers with an underpowered amp/receiver than an overpowered one. Distortion/clipping is what tears speakers apart.
