Subwoofer sitting on uneven wood floors - easy fix?

post #1 of 13
Thread Starter 
The wood flooring in the corner in which I have my sub is slightly uneven and therefore the sub itself isn't sitting well on all four legs.

I know they have the overpriced pads that you can put under a sub but I'm wondering if something more inexpensive like a square of carpet or a square of an anti-fatigue mat would work just as well? Right now I have a small folded piece of paper under one foot as a temporary solution but I'd like something more permanent. I feel like I might be missing some easy answer here.

A piece of carpet would do fine. You can find foam mattress toppers from Walmart for around $10 that would work as well. There's enough material in these to make multiple pads, or double up if you want it.

If you have a downfiring sub, these soft mats have the added benefit of absorbing distortion, whereas hard flooring would reflect it making it more audible.

Adhesive felt pads (example). Trimmable and stackable. If you're worried about slippage, use rubberized pads (example) instead.

I use a folded piece of paper napkin to take up the uneven floor wobble of one of our subwoofers and if one stops looking at the piece of paper doing stabilization duty, immediately the fix becomes permanent. Well, it does in our case.

With a wood floor you really want to put a non-reflective pad under the entire sub, like a piece of carpet, to not only stabilize it but also damp above bandwidth harmonics.

Are the feet screwed in? Same problem here and I just raised one foot to level it out...

Can't get any easier than that.

is that recommended for all subs on hardwood? I have a dinky 8" front firing, rear port design.

It won't make any difference, since the harmonics that the rug will damp with down firing shoot straight into the room with front firing.

You can however get this effect by orienting the sub to have the driver fire into a wall, and then carpet that wall. biggrin.gif

My sub is a front firing driver with a down firing port. Should I still go with the carpet option?

For the stability yes.

You just won't gain any audio benefits from the padding as ports don't produce above bandwidth harmonics, I believe I've heard Bill explain before.

The output of the port is down at the lower end of the sub passband, so there aren't any harmonics coming from it to damp.

Thanks. I realize it was a noob question but just wanted to be sure.
