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.

Love to help you hilde45 but helps a lot if you a) ask what you really want, b) use words to mean what they actually mean and c) pay attention to the answers. 

We are now down to a very specific problem, "a +5db or more bass hump from about 73-92 hz" at least until it changes again. Main obstacle now being c) pay attention to the answer. Will you do this? Because I am not about to waste my time on another one where someone has already made up their mind. Why? Would you? 
Search audioKinesis posts and you will likely find the info you need.

The key I seem to recall is to have the subs in the right locations to randomize the bass waves to provide a smoother response throughout the room. Might be harder with 3 versus 4.  
MiniDSP makes a unit that integrates up to 4 subs.  Look on YouTube for the lengthy but detailed instructions.  Mostly for Home theater but concept is the same.

Pardon my probably obvious questions. I’ve been contemplating how serious I want to get about subwoofers. How many and what size and what budget and where I’ll put them and how I’ll connect them etc, etc.

is the 5dB bump there even without the subs active? (Is it the room or the subs?) Can you drop the crossover frequency enough to effect the bump?
