Woofer Pads....

[ZenG]

Have you used these underneath your cabs or combos when you:-

Play in a basement that has carpet over concrete..or to isolate the rig from a solid wooden floor..or any other reason...
and did it/they clean up the low frequencies or give you nicer low frequencies etc ?

I use an Auralex Gramma out on the back porch (concrete), and on my wooden cabinet. It sounds better in both applications & there is no vibration induced in nearby walls, which I had a problem with before.

Might help a little if you have an extremely resonant stage floor. IMHO, a high pass filter like the fdeck 3 is a better bet for tightening up the bass.

I usually play on a pretty hard floor..at least that's where the amp is sitting. The room isn't hugely big.

I don't have the Auralex..although I just looked them up on Amazon to see what they were...

I just decided to try fooling around making my own because I have quite a bit of softer rubber mat plus other material laying around. Made a pad that's about an inch or so thick.

Well that worked pretty good. Sounds nicer already. Have to see exactly what an Auralex is composed of...might get one of those yet still.

Is the OP referring to these?

Gramma pads under my cabs in my living room. I'm on raised hardwood floors, and I have common wall neighbors, so they appreciate it. It does tighten up the bass and reduce rattling. I've used the pads at higher volume and the benefit wasn't as noticeable, though that could've been for other room reasons.

Isolation devices don't work. If they did every seller would have measured results with and without them. The only measured results I've seen are here:

A pad can keep your cab from rattling at high volume on a hard floor, but it doesn't have to be fancy or expensive. A yoga mat cut to size will do.

I don't know about "isolation"....but as far as cleaning up the bottom end in the room I'm using it worked for me.
If it worked in my application that's all I'm interested in.

And it did.

Enough that it can actually be recorded so others can hear the difference?

Concrete is the least likely surface where any sort of pad would have an effect.

Filters do great things and my amp always sits on an Auralex Gramma. IMO a filter and the Grammar accomplish two different functions.

The filter helps you focus/reduce boominess in your sound and the Gramma isolates/decouples your cabinet from it's surrounding surfaces.

A pad might isolate the cabinet from the floor, but it does nothing to keep any surfaces (including the floor) from vibrating sympathetically with the sound waves.
