In Reply to: How to position speakers in room 8 ft wide but 35 feet deep? posted by Jick on January 31, 2001 at 12:14:25:
8 feet is way too narrow and when I did listening tests, no was could I get a precise vocal from the middle. Stereo separation was well compromised.So I'm just back to putting the speakers against the long walls which is much better, except for a little boominess. Putting port plugs sucks the life out of the bass totally, so anyone got ideas on room teatments? Perhaps I can put my speakers 12 to 18 inches from the long wall but but put some kind of rug behind the wall, right?

I have a long/narrow room too.
Sometimes bass boominess is caused by overlapping resonances.
Measure the distance from the center of the woofer to floor, back wall and side wall. Those measurements should be as different as possible, no distance should be a multiple or even an even sub-multiple of the other. For example, 20 inches distance from woofer to the back wall and 40 inches from the floor is a NO-NO.
If possible, use assimetrical placement, at least make the distances to the side walls unequal.
Repeat the measurements for the bass reflex port, if present.
Also, use a Radio Schack sound meter and a Stereophile test record at around 70db, C weighting, fast, to look for the speaker position that has less bass resonances. I prefer the analog meter.
Good luck
