X-over question

Some speaker manufacturers advocate low order slopes in their (passive) speaker designs in order to preserve phase relationships. Conversely, the new digital room correction/x-overs (DEQX, Tact, Lyngdorf) allow very high order slopes because the digital crosses allow this approach in the digital domain - purportedly without impacting phase. My question:

What about active, line level X-overs in an analog, bi-amped configuration. Can anyone describe the relationship between slope and phase for this type of x-over?

Thanks,

Jburidan,

Thanks so much. Perfect, you could not have pointed me to any info more directly on point. I understand that other articles may offer a different point of view, but the 2 part piece you identified has all the relevant info I was seeking.

Thanks again.

Shadorne,

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.

or

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

and

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.
