FI BL 15" Box

[eradicator006 10+ year member]

How well would an FI BL 15" dual 2 ohm work in 4.33 cubic feet tuned to 31hz?

I have this box I made for my 2008 RE XXX 15" and the XXX doesn't perform too well in this box. I figured it may be more suited for my 15" FI BL. I'm also planning on getting rid of my extra batteries and running the BL at 4ohm on my amp (rated 1000@4 ohm). I've been driving around for 3 months with no sub stage. I'm enjoying the increase in fuel mileage but I am missing the bass. I thought I could downsize a bit.

Well, I have BL 18's. And I had a Q 15, and all of them work so much better in a larger box.

Here is the only pic I have at the moment. I think this is a 2006 model. I got it used in 2007 and it wasn't very old. I don't have a pic of the bottom but there is not much to see. No vent or anything like that.

First gen= 3 slugs, 2nd gen = UFO, 3rd gen = neos

On the magnet in faint writing is written "bl d2"

Some 1st gen btls came with 2 slugs. The 3rd slug was actually an option. Almost everybody got this option
