I get the thought process on the choice of sub. Being a fabricator and box builder, I would have talked with you about ideas outside the box. Instead of 1 10" upward firing in a sealed enclosure, I would have suggested two 6 1/2" forward firing with a ported enclosure and done one long slot port to smooth out that bass or two short ports for that in your face bass. All depending on your listening habits and choice of music. I've just been doing this on a professional level for a long time, and I'm not afraid to get creative!!!
