Just bumping this up in hopes of an answer. Thanks.

FWIW - to briefly answer your question - with an active analog filter you can control pretty much what you want - phase accuracy, damping, quality factor, slope - all by the design. Digital filtering is even more powerful and extremely flexible (big advantage in prototyping) but may introduce latency and is expensive (computing power needed). If you are building a few speakers then I'd go digital as the extra expense is worth it. If you are building many speakers then it makes most sense to finalize the protyotyping using digital filters and then design a good (but cheaper) active filter.
Thanks - I'm not designing a new speaker but I am more interested in either:
A) integrating a bandwidth limited main speaker with subs using a "traditional" active line level analog cross (Velodyne DD software is an inexpensive and promising looking option) with a crossover point, room correction and level matching below 200hz.
B) going the TacT, DEQX, Lyngdorf route which, although much more expensive will allow full range dsp room correction.
Thus, there are at least 3 issues:
1) IMHO, I need bass correction as my current room has more audible issues in this region than previous rooms. Therefore, issue #1 is which approach best solves this _Velodyne style or TacT style bass correction.
2) Do I want full frequency room correction
3) The Tact style allows the introduction of a digital domain x-over, while the Velodyne (I assume) crosses over in the analog domain.
This question was asked to better understand point #3.
Thanks for your input and you can be sure I'll check out your link toget myself better informed.
