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.

@golfnutz Happily.

Working very well in my room:

1 REL Sub (further away)
Phase: 180
Crossover: 100
Volume: 7 p.m. (3 tics)

2 Rythmik F12SE Subs (both behind and to the outside of each main, but not exactly equally):

Both set at:

Phase: 180
Crossover: 40
Volume: 7 p.m. (3 tics)
LFE Pass filter: 50hz
Rumble filter: Off
Extension Filter Freq: 20
Extension Filter Damping: Mid
Poorly designed rooms will ALWAYS have peaks and nulls, feel blessed your's are not any worse than what they are. Are these devotions from ruler flat response something you are hearing that affects your listening pleasure or is it something an electronic piece of equipment is telling you is not correct? We build rooms that are exclusively for 2 channel listening, after the initial construction is done we begin the laborious task of tuning the room to each owners personal taste. We have built approximately 100 of these rooms and have found that very seldom does a client ever choose ruler flat response (or as close as we can get to it) as the preferred sound of there room. Ruler flat response is over rated. Electronic equipment can help you achieve better sound but it (and other people) cannot determine what is the best sound for you, only your ears and brain can determine that. 
Right!
So how does it sound?

It can’t be complete  until you do the final tuning to your ears with music.  You have to jump ship on the measurements at some point.  That just gets you into the game.

You have to jump ship on the measurements at some point.

I’m not sure if you’re giving me this piece of advice, because I mentioned (I thought), I’m going back and forth, measurements to listening to measurements, etc. Better measurements reveal themselves in a listening experience that reveals more than I was hearing before and it has raised my standards, both as a listener and in terms of what I knew my room was capable of. It’s easier to give me advice if I’m a "measurementalist" but there’s no way that impression could be fairly assigned to what I’ve been saying. Listening is the final test, because after all, I didn't buy a hifi rig so I could run sweeps!

@arrowheadrss Not sure where I expressed a fixation on ruler flat response. That’s not realistic and I know it’s not desirable. I’m treating the measurements as one might treat a BMI reading. If it says you’re obese, well, who knows if that’s the right word, but it’s safe to think that dropping a few pounds is to your benefit.
