Subwoofer in the corner? Forget about it


Since installing new horn speakers, I have been learning a little about extracting their best performance. They require some effort and knowledge to get right - and the effort is the easy part.

Following "common wisdom", I placed the sub in the left corner, to the rear and outside of the left main speaker. The result was a disaster.

Boomy, one note bass, little tone and texture, very uneven response at different locations in the room, and no musical connection. This wasn't good enough for screening reruns of "Deuce Bigalow: Male Gigolo" on a HT set-up.

I repositioned the sub to the midpoint of the right-side wall. Now, it is a little forward and to the side of the right main speaker. Initial results are promising: Lower bass output (expected going from 3 corner boundaries to 2 wall/floor boundaries), coupled with musical LF, toneful and engaging. The difference between just moving alot of air and making proper musical bass is huge.

Here are two articles I found interesting:

http://www.audioholics.com/techtips/setup/loudspeakers/SubwooferplacementP1.php

both use models and measurements to confirm my listening experience - corner loading the sub is loud and rough, compared with other locations. And multiple subs are smoother than a single sub. Now, I just have to bite the bullet and make room for another refrigerator sized horn sub in my listening room.

Even better I placed my two subwoofer cabinets on their sides in front of the center channel speaker.There are no suppoorting walls, just the floor.The output dropped about6-8db but it was quite smooth.Corners stink.
