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.

hilde 45, relative to Sub Woofer Placement 3 Subs are IDEAL!

Here's my solution for  optimization of results, with 3 subs.  

1) Set of 12 inch, self powered 500 Watt Subs at Far Left & Right of room, set @ 70 HZ Crossover.

2) Single 15 Inch Sub Directly in Center. This Sub Woofer is Fed its signal from a dbx 234S Electronic Crossover set @ 40 HZ Crossover Frequency, & set to SUM Left & Right Channel Inputs, which signal is in turn fed to a Classe 25 in Mono Mode, putting out an honest 1,000 Watts. dbx 234S gets its signal directly from the second output of my pre-amp.

3) Combined with PS Audio BHK Signature 300 Mono Blocks, feeding a pair of Anthony Gallo Acoustic 3.0's, three way speakers.

This combination of Speakers puts out Exceptional Non Boomy Bass with Massive Slam, as the 15 Inch Sub Woofer is driving directly into one, when they are sitting in the sweet spot.

I find the "Single Very Low Bass Sub", summing both Left & Right Bass signals to be optimum for Deep Bass, while not interfering with the music that one plays.

Try it, you will like it!
WOW, is all that I can say!

FLAT to 4 HZ, that is one Hell of a system, that obviously an be FELT & HEARD!

Just, what Maximum  DB level do you measure with your system?
