Ok I have read alot on this product on other sites any thoughts here? :rolleyes:

Um, yes...just buy the damn thing. Assuming you're thinking of using it on you subwoofer(s), you simply can't go wrong. It would be a bargain for five times what you can buy it for online.

Rob:
I assume that the BFD only works in one sweet spot?

I have been tempted to buy one (it's certainly cheap enough if it solves my poblems) but I have found a ~15db swing when I move my RS meter 2' to either side of my sweet spot in my troubled 13' square room.

How can A BFD help when a person seated to either side of a sweet spot ends up in a null or peak that's different than the metering position?

Believe me, I don't mean to sound confrontational at all. Many have posted very positive results with a BFD... I've just never had the opportunity to ask them if it's useful only in one spot or how problematic their room was when they started! :confused:

Well, that depends a lot upon your room. Certainly EQing a sub will affect the response outside the "sweet spot," but the general idea (at least for me) is to optimize the response for the location where I sit. The laws of physics pretty much dictates that it's almost impossible to get truly even, flat response thru the entire bass range in a smaller room, at least without staggering amounts of room treatments (ie anechoic chamber).

Using room treatments will get you a bit more even bass throughout the room, but even this won't achieve total balance in all locations. A complex system of wave interactions occurs at intervals based on room dimensions & wavelength; some of these interactions reinforce while some cancel, creating peaks and nulls. By EQing out the peaks (nulls are very hard to deal cure with EQ), you do get smoother bass in all areas, although this sometimes results in even weaker bass in null areas.

Yeah, a square room is a ***** to deal with- it's probably the worst possible shape that you could have in practical terms. On top of the shape, the small size can exacerbate the problem. A Behringer should help a lot, although you will run into the problem you describe. As you say, they're so cheap that you won't be out much, but I'd be surprised if it didn't help at all.

Thank you for your responce. I think I will just go buy the damn thing :D
