z2300 burning smell.

[WeStSiDePLaYa]

i bought a pair of refurb logitech z2300 speakers. sounds good. but when ever i turn them up really loud they give off a burning smell. its not just mine either, others have had same problem.

im assuming this is not safe is it?

seems something may be overheating. is there anything i can do about it? maybe open it up and heatsink the hotter parts? or maybe i could cut a hole in the sub/amp and put an 80mm fan in there? i have a 14dba 80mm fan i could use. would it affect sound much?

Re: z2300 burning smell.

is it has external power brick? did the smell really come from the sub/amp?

i think a hole in the subwoofer box will affect the sounds greatly.. not to add a fan.

So they finally have Smellovision.
Been waiting 20 years for smell to come from speakers.
What were you listening to?

no, the amp is built into the sub box. im not sure if the compartments are seperated or not. and yes the smell really came from it, i could smell it being pumped out of the port hole. other people also have this problem.

Re: z2300 burning smell.

My sub woofer with built-in amp has a heatsink on the rear.
The sink is rather hot to touch. I just attached a 8cm fan on it and
now, it's cool. I also moved the transformer outside of the sub, to reduce heat & increase volume inside the sub box.

For your THX-certified z2300, 200w output may give much heat.
To increase stability, I suggest to add a slow spinning fan to the heatsink
if the heatsink is on the rear.

Futhermore, bad smell may be a sign of overheating. Some EI transformers are very hot during operation especially those cheap speakers with under-rated transformers.
Some of the better speakers come with toroid transformer which run more cooler.
