And your second assumption is wrong as well.
First, DD-EQ/MRC:
What I would like to do to get more evenly distributed bass in my "problem room" is this:
* I first make a rough calibration of everything but the DD-12, to give DD-EQ a base to work on. Just automatic MRC. * Then I turn on the DD-12 as well and calibrate with DD-EQ. Less dips and tops in the frequencies.
* After that a "real" MRC run which should now only fine-adjust, shortening reverberation times somewhat.
You can't use MRC this way though. You either run MRC first or you run MRC last. You can't run MRC multiple times and apply multiple passes. The 2nd run wipes out the results of the first run.
You either use Digital Drive or you use MRC first then you use the other.
In my experience, using DD-EQ first followed by MRC gives better results than running MRC followed by DD-EQ.
The problem is that the two subs play different musical info (front/rear) and can't really help solve the acoustical problems as I have intended.
So, I want them both to play the same bass information - all bass information.
Well, there is the fact that you have two physically different subwoofers which is a less than ideal circumstance.
They have different performance characteristics and assigning them identical content probably goes against sound acoustic practices if you'll pardon the pun.
Currently, with two identical subs you can have them left/right stereo. With two non-identical it's (kind of) front/rear stereo... I want "real mono" (but that's what I wrote last year and probably that made Meridian understand nothing at all...
)I believe using two non-identical subs as a stereo pair would be very difficult to implement, and at least hard to get as good as needed to have any benefit from it.
"Real mono" would feed 1/N of all speakers to each sub + 1/N LFE where N is the number of supported subs. That's what you want for disparate subs.
I want to have the crossover low, so the bass info will be non-directional anyway (apart from the occasional LFE track with frequencies 80-120Hz). And I think this mode "Send all bas to both subs" would be rather easy to implement, it ought to be.
I'm sure someone would want to be able to have a non-matching pair as stereo subs, but that's not me... [/qb]
The crossover is a seperate issue and as long as you don't mind the same crossover being used for all speakers and this is already covered.
