Help me tighten up my sub sound (1 Viewer)

[JoshuaHoffman]

I have a Yahama 8" 120-Watt Powered Subwoofer and I'd appreciate some modification advice in "tightening up" the sound.

It's hard to describe the sound. I would go with "airy" and "hollow", meaning that it sounds like the bass is not crisp but unfocused. It does not sound "floppy".

Can anyone reccommend some simple modifications (and I'd appreciate a link to any products) I can do? I think this sub could be solid if I could tighten the sound up a bit.

Right now, I need to keep this sub. I have a better sub, but currently it's much too big and too loud for my current living situation. So please, only advice on how to modify this sub!

Move the sub to a corner and see whether that helps.

Another forum told me to do the exact opposite Charlie.

Corner loading will give you the most gain, but to tighten up the bass of a boomy or loose sub, you would move it away from the corner. The side effect of this though, is you will lose the gain from the corner, reducing your total output and probably some extension.

To tighten it up, the least expensive, simple way would be to add a bit more poly stuffing. You can find polyester pillow filling at most craft or fabric stores. Remove the driver, and see what's in there first, then add a little more if it isn't full already. Next, add some weight to the top of the sub, say 10 lb or more (be creative). This will hopefully tighten up the cabinet some, yeilding a little less resonance (depending on how good the cabinet is).
