Thank you to Don C. for putting me on track for 250Ti upgrades.
I also feel the next step for me is to build two 8 or 12 sq. ft. subs using the 2245H. I'm considering using separate NHT X1 crossovers for the sub and the 250's as my preamp has separate inverting outputs and is a high current model so I could easily drive the separate amp for the subs. Any considerations from those having done this?
