Jacked Up Subwoofer

[Apotherix]

I have no idea why its doing this, but lately when I turn up my Logitech Z-5300 speakers up past more than about half-way the sub starts to make the weirdest noises. It doesn't sound incredibly awful, just like the sub can't really hit right or something. It used to be tight as a whistle, but now it seems hollow for some reason. I turned off all the software EQs that I had going, still the same thing. Any ideas? Should I send the things in?

Is maybe something near causing interference? Have you tried moving it?

It's not blown out is it? I know that blown out subs were an issue with certain Logitech speaker models when people turned them too high without breaking them in.

Did you move it? Placement can have a huge impact on sub performance.

Try placing it in a corner and see if it helps if you just moved it.

I didn't know that.

Yeah, a good way to pick sub placement is to place the sub at the listening position (your chair/couch/whatever) and then walk around the room until you find a spot that sounds the best when it's playing. Ideally you'd have an SPL meter and you'd be doing frequency sweeps to see where you get the flattest response, but yeah....
Once you find a spot in the room where the sub at your listening position sounds good, if you put the sub where you are standing, it should sound good when you're at the listening position.
If you don't want to go to that trouble, just placing it in a front corner is usually best.

Yeah, its in the front corner. I haven't moved it forever. And I've had the speakers for quite a few months - although I did crank them up quite a bit even when I first got them. But why has it just started doing this? It sounds like it might just be blown out. I sure hope not. How could I tell though if it was?

Do you have a portable CD player or other audio component you could plug in to your subwoofer & satelites and see how it sounds?
