Cabinet "tone tightening" materials?

[Sludgenutz]

First off, I love the combination of the EVM12L/Eminence "Swamp Thang" combo in my Mesa Recto vertical 2x12 cab. I was thinking the next step would be tightening the bass response a bit.

Unscientifically running the outer dimensions through a calculator reveals the vertical cab is roughly 20% larger, compared to the rough outer dimensions of the Mesa Recto horizontal 2x12 cab.

Is there a stable, economical, non shedding, material that can be installed in a cab to prop up the thump a bit?

Get an Auralex Great Gramma pad - I picked one up last month and was astounded by how improved the bass response was.

A while ago there was a post... someone from like the Netherlands posted or something. Night something was the name. Anyways, he took a 1960A cab and removed the back panel and replaced it with a real birch backpanel. Then he added something like eggcrates to the inside bottom and sides of the cab. Apprently, that made a big difference in make the cab more tighter and compressed. Do a search for that thread, it should come up, he even took pictures IIRC.

If you want a lower internal volume, and easy thing to try is to build some kind of box and stick it in there.

Are you thinking that making the enclosure smaller, like the horizontal cab, to tighten up the bass? Not sure it would have that effect - having both speakers closer to the floor would (I think... )

If you want to increase the effective interior volume, here's some stuff: http://www.partsexpress.com/pe/pshowdetl.cfm?Partnumber=260-330&raid=44&rak=260-330

going from a strictly bass point of view, there is an optimal volume for a cretain speaker. If you go larger than that, it does get "boomier", so if that is the case, making it smaller will tighten it up some. Try bricks in there, after all it doesnt weigh enough now......
Just kidding about the weight, but it would let you know if a smaller enclosure is the cure.

The Bogner cabs have a sheet of Corning insulation on the inside of the back panel. It kills standing waves.
