Randy,

I was looking at waterfalls but honestly, donít fully know how to interpret them other than to know that the decay times should be as uniform as possible across the audible frequency range. Before I did this, the decay in the low end was very long. Now the waterfall looks much more uniform across the range.

That is the extent of my knowledge (or not).

All my final/fine tuning was by ear.

I only used REW to highlight where the issues were and to simulate my room and see what speaker and LP locations changes would do. It is a very useful capability of REW.

Does the CR-1 allow you to adjust the LFE while still controlling two subs, one for left and one for right channel? Ultimately I would like to SUM the LFE with the left and right channel.

Beats me. I would call Barry Ober, The Sound Doctor.

You got it. A long decay time will result in bass that sounds one note or thudding. Long decay and louder frequency response tend to go hand in hand because they are each manifestations of a standing bass wave. If the decay times are relatively even, I find that heavy handed EQ of frequency responses sounds dead. You were smart to target only the two outliers. Finally, I am betting that the newly crisp bass is because you eliminated some impulse edge lag when you stuffed those ports. Bravo!

The DARO eq of the Fathom took about 3dB out of a bump in the 50-60Hz range and its location does not generate the suck out around 100Hz.

There's a stereo input (actually balanced or unbalanced) labeled "managed bass input" in addition to the main inputs. There are several possible output schemes that allow you to do as you propose. This is a great sounding crossover. In fact, it has no sound at all in the best meaning of the term. And some fun to play with too.

Looks like this mode just removes the CR-1 from processing.

That is my understanding as well. It seems to allow a Surround processor to manage the output of the sub when you want to use it for TV/movies and bypass a two Channel setup for example. I am not using it with a surround processor so canít confirm however.

I havenít read anything in the manual and donít think the CR-1 has an accommodation like you asked about.

As I think it should because you're wanting to pass the pre-processed LFE channel, no? You should still get the processing on the main units. Like CR, I don't use it in conjunction with a surround system....just as a stereo crossover for music so maybe I misunderstand something about that.

Edited: I did misunderstand, though I shouldn't have. You want to mix them, not pass through.
