View Full Version : Help: Enclosure for TRF2212

02-26-2010, 10:07 PM
im looking for help on building an enclosure for 2 TRF 2212's shooting for under 43hz these will go in a trunk and i have 15Hx32Wx28d to work with. prefered tuning would be around 36hz. i tried a an enclosure of around 2.8cubes tuned to 45hz and it was tottal falure. These woofers need something seriously different in the port department.

helps greatly appreciated.

also would like to build an enclosure for just one of them for starters using the same dimensions.

and please dont leave responses such as "this is a fart/burp sub only" and its a "60 hz sub" BS you can build a box for it.. to play low.

I'm not sure about building your own box but I know Atrend has a couple of pre-fab SPL enclosures that fit the parameters that you are working with. You can check out the SPL 12SV Welcome to Atrend Usa ( or one of the Black Pearl's Welcome to Atrend Usa ( , and i'm sure you can get the tuning frequencies by contacting them (even though that kinda info should be listed). Both are 1' boxes perfect for competition level subs.

The 12LSV also falls within your parameters Welcome to Atrend Usa (

Vitveet has a pair of these subs and does boxes.
