Smoother bass by running woofer out of phase?

You are right, in that I am satisfied with the amount of bass I am getting in out of phase mode. Also there is considerable more space and dynamics. What nags me is whether or not this is the way to solve the problem. I got this idea from owning a Rel sub where they suggest in hooking up the sub out of phase which may reduce bass boom. By the way I am not currently using the sub in my system. I thought about using an EQ like Rives, but maybe I would get the same results.

I had a similar problem that was solved perfectly by Rives' PARC. Well worth the investment, but make sure it's set up by someone competent, optimally using Rives' BARE system.

Of course it is not correct - you are changing the impulse response significantly. This may be why it sounds more spacious...probably more laid back - less distinct on transients or muddy. The inteference pattern that you create will have a null down the center line of the room (if it is symmetric). A better solution would be tone control or PARC or placement further out into the room. Electrostatics are designed to be placed well out in to a room (less bass reinforcement) and therefore it seems likely that ML's will bass heavy if placed up against a wall.

My room dimension is 13x30. I have the speakers set up on the short wall. The speakers are 5 feet out into the room and 2 feet from the side walls. Listening chair is 9 feet from the center plane of the speakers. The floor is concrete with double wall construction. My ceiling slopes from 10 feet to 7 feet from left to right. Carpeted in the seating area bare painted floor in the speaker end. Perhaps then my only solution will be to applied some sort of EQ in the low freq.region. Thanks guys for your input.

Interesting that you find that it sounds better with the woofers out of phase, in as that back in the early '90s, when Stereophile reviewed the Martin Logan Sequel IIs, that they too found that if they wired the woofer out of phase, that it too sounded better.

Thought you might find that interesting.
