SLA Pro Dampening

#1 Post by Tedward » Sun Aug 21, 2016 6:04 pm

Started a pair of SLA Pro's and I 'm ready for the carpet felt. This stuff is hard to come by in my area (Southern California). Seams the foam is what is used around here. Can I use 1/2" carpet foam or I have some 1 1/2" convoluted foam?

Carpet foam isn't always open celled. Mattress foam is OK, but the advantage to felt carpet padding is it's so thin, much easier to work with in the small confines of the SLA. California or not I can't believe carpet stores don't have felt padding. I wouldn't want foam padding in my McMansion. 8)

Thanks Bill, kinda disappointing. I can special order it from HD or Lowes but don't need yards of it. Since I have plenty of matters padding I'll use that.

Try a real carpet store. Just like with plywood big boxes don't carry the good stuff, only the cheap stuff.

Texas uses the foam padding for carpet. I have never seen "felt" padding here.
I'm thinking giving Acry-Tech Acoust-X a try.

That stuff is used to dampen the ringing of thin sheet metal in car doors, plastic body panels in cars, etc. It works similar to holding a bell or cymbal with your hand as opposed to letting it ring out. It isn't meant to damp the actual sound wave propagating though the air. It is essentially a paint on version of the following:

Built:
17" width 10" driver Autotuba
2 x 29" width dual Lab12 Tuba60
6 x DR250 2510/asd1001
In progress:
2 x DR250 2510/asd1001
For best results, point the loud end of the array towards the audience

What about jute carpet padding that is used in automobiles? I've seen that at 1/2" thick. It seems to be reasonably priced too.

Jute should be fine. It's basically the plant based version of felt, which is wool.
