Subwoofer Question


Has anyone setup a subwoofer at 90° off axis to the listening position and gotten it to integrate well?

My sub is currently near the front wall between the two satellites, and sounds quite good there. However, because of my limited space I may have to move it halfway between the mains and the listening position, and place it on a side wall. It's a front firing sub with an external[separate] amp/crossover. The room is 12 by 16 feet, with the mains on the narrow wall.

I don't have a dedicated listening room. This is a bedroom that also serves as an office/home theater/music room, so space is VERY cramped. I'm very hesitant to do this, but would like to hear of any success stories if there are any.

Thanks.

Try putting it in one corner behind one of the satellites. Try the right corner first.
PS: In most cases (not all) I find it hard to integrate a sub putting it on a midpoint away from the corners. Some will disagree with this, however may subs were designed to be put in the corner, so try the corner for a while and play around with the crossover and volume settings. Much better to have a low frequency crossover setting and more volume than vise-versa.
Thanks all for the great advice!

I just got a Bel Canto DAC 1.1 yesterday and the bass I'm getting now is unbelievable. Very detailed, tight and deep. I'm even more hesitant to move the sub now. I failed to mention that the alternative to leaving the sub where it is, is running 16 foot speaker cables. Maybe not such a bad option after all.

Wirehead, I researched subwoofer setup articles on the net and found several that advocated your crawl and listen approach. I may do it just out of curiosity. I have to know now! I'll make sure I lock all doors first. :)

Chas, thanks for the detailed procedures on matching gain and crossovers. How would phase adjustments play into this? Should I initially leave the phase at 0°? Or immediately change it to 90°, or just find what SOUNDS right?

Sugarbrie. Unfortunately, I don't have the option of placing the sub in a corner. I have dressers and an HT equipment rack occupying those areas. In my room, I have found your idea of lower crossover settings matched with increased volume to yield the best results. Higher crossover settings always muddied up the lower midrange.
Gunbei:

Initially I'd leave the phase alone, and try to get to where you already are in integrated bass before fooling with it.

The process for setting phase on a sub is a little complicated and is best done with a test tone cd. What you do is reverse phase on your mains, then play the test tone at your crossover point. Sit in the listening position and have someone else adjust the phase on your sub until you hear the LEAST bass. That will be the perfect phase adjust when you return your mains to normal. Seems whacked, but it works. The other option of course is simple trial and error - try 90 degrees and see if it's better, etc. Use music you're very familiar with that has a strong bass presence, and you'll likely get pretty close. At the very least, you'll get to pick what sounds best to you, and isn't that why we listen?

Have fun!
