Well, it may be staying for a little while longer. The subs I just got for Mark and I are too deep for the space I have available above my amp rack. I actually really like the sound of my current sub a lot so its not a huge deal, it just takes up a ton of space.
I would put it in the house as a HT sub like I was intending to do originally, but the "boss" doesn't like the idea...

Yes I already have a plate amp that works quite well for the sub in a HT environment. Looks like I will just try and sell it if I can find a buyer. Sure was fun to make though...
