What process did you use to integrate multiple subwoofers for 2 channel listening?

Today I will be trying to integrate up to three subs. Two are matching Rythmiks F12SE, and one is a REL R-328. The Rythmiks have a variety of adjustable parameters, including phase, crossover, and gain. There are other switches and passes on the sub, but I'm going to try to keep it basic to begin with. The REL has variable gain and crossover; the phase on REL is either 0 or 180.

I have REW for measurement. I will be buying a few more furniture sliders this morning, on doctors orders. ;-)

QUESTION: If you have multiple subs, by what process did you integrate your subs? One at a time? More? Which adjustments did you try first and in what kinds of increment?

I know that trial, error, measuring, and listening will all take time. Rather than look for a needle in a haystack, I'm curious what sequence or process was most effective for you.

Thank you.

It's a mistake not to use digital room correction in addition to several subs and sub placement. If you add it to your digital chain it will only improve your sound.

For me Dirac bass management plus additional (to my hearing) Roon PEQ filters works fine to give impressive lower and upper bass.

If your only concern is a +5 db hump then you're really fortunate. More normal would be +/- 20 db between 20-100 hz. With one or two nulls.

Minus 5 db is not a null. It's a small dip. A null is an infinite dip. Your problems seems to be more in the high bass/low mid. If you can trust your measurements.....

I believe that was very good advice from the manufacturer. No dsp software is perfect but you won’t succeed without. You may think so though...
