Multiple subwoofers?

[qguy]

Sometimes personal preferences gets in the way, I adjust my subs using audiophile recordings/materials and every time I play audiophile recordings their perfect. The problem comes from those less than stellar recordings that contains too little or too much bass.

If your subs are dialed in properly there is no need to constantly adjust them or turn them on and off for different program material.

A good number of articles on distributed bass using multiple subs in rectangular rooms suggest placing them midway on opposing walls (front and back or left and right) for the most even (though not loudest) response.
I did the front and back once upon a time and it worked very well. The bass literally seemed to surround the room.
I think although we supposedly can't hear where the bass below 80Hz is coming from I seem to sense it when it's coming from one corner.
Just feels odd to me. With just a single sub my preferred placement is behind the listening area.

Correct for the most part. My corner placed single sub blends in seamlessly with my mains that go down to the low 20's. The only time I feel the need to use that sub is after a few good ipa's when my hearing isn't quite as acute. Dual 18's imo is overkill in my 16X30 room even after several ipa's. I've also done sub crawl for placement and there's a spot that didn't have optimal bass even with dual 18's. My fix is to not listen in that particular spot and thankfully it's not in the sda sweetspot.

If your sub is too much in a 16X30 room perhaps you most likely have it turned up too loud and/or the internal crossover is set to high. That's why I used REW a DSP and a calibrated mic to adjust my subs. It was a royal PITA but IMO worth the effort.

FWIW: My subs are on whenever my system is. There is no need to adjust them as they were dialed in using measurements.

When I got my first active sub I was really surprised how low I had to set it to make it blend in without sticking out like a sore thumb.
Most people who are happy with their subs will say you don't even know it's on until you shut it off.

FWIW I've never used a mic to set up mine and I've just depended on my ears. As far as the crossover being set too high I have it set at it's lowest setting at 40hz since my speakers play into the lower 20's. It's also very noticeable to me when it's "too loud" and I rarely adjust the sub's volume as it stays a bit under 1/4 volume 99% of the time. I will admit that same sub is a helpful addition to my khorn based system which does benefit from the extra bottom end where they're lacking. I'm not against subs but I believe they are speaker-system dependent and there are situations where they're overkill and can overemphasize bass content to a point where it's not pleasant to listen to them long term.

Even though I don't like subs I have seen it happen many times over that two subs are better than one for installation I supervised. I wouldn't use them in the sum mode for Low frequencies, but as a supplement to each individual channel. Its just a personal choice on my part.
