I was going to use it for a custom Nomex-tc2+ 12" ::Sexy:: 1.8 ft3 enclosure. Which I have already drawn the plans for on 1 4'x4' board.
I'm picking up a Sound splinter RL-p 15" D2 tomorrow and wood love to hear it in a 3.5 ft3 ported enclosure.
I also bought a eD 160v.2 D2, which ended up fitting my TC-2000 enclosure perfectly. I'm going to put this in the back of my wife's ride with 500 Watts @ 1 ohm, in 2.0 ft3. After listening to it for a while.
