I used to build (heck, sold) LTs so that is fine. I just am not keen on the massive TC sounds pricing with the LMS or Axis line.
The ultimax ported in a 2cuft box wouldn't be practical but I do agree that if I could manage larger, that ported would be good. My theater currently is a hodge podge of old equipment that is kind of an eye sore (space wise). Currently have a Tumult with dual 18" PRs that's rather large, and it would be nice if things were a bit smaller.
The SDX 12 in the pair pricing is worth considering. The Ultimax 12's were on sale yesterday for $155 shipped each and I imagine that'll happen again and that is a pretty good price/performance ratio.
