They'll still probably let you trade them. Or you might be able to sell/trade them to someone here for M22s+sub or M60s.

Would the Behringer Feedback destroyer Pro help this guy? Evidently, many have had good luck using it's parametriq EQ to take care of some pretty bad bass issues, and it's only $120.

He'd need a pair of them if it worked at all. I suppose if you had pre-outs and main ins a pair could work. 'Course I suppose that you would need such a beast for any eq.

Edit-forget the pair. I just d/led the manual, which I should have looked at first... dur. So just how does one use this beastie with a sub? And is a TDS jack the same as an RCA jack?

I assume that the reason people are using these is because they include a parametric equalizer and they're cheap, not because it's a use that the manufacturer envisioned.

asher, just so we don't miss anything - have you tried adjusting your bass or treble on the receiver?

Ash, welcome. If the room dimensions that you described are accurate there should be no room modes between 32-40Hz, but a very strong one around 43Hz. This would be caused by the identical 13' height and width dimension(coincidentally, on a thread yesterday we discussed a bass problem with Mark Johnson relating to his 13' square room)causing a double reinforcement at that frequency(560/13~43). The speaker placement to reduce the problem isn't especially practical. The woofer cones would have to be raised to about 6-7' from the floor, where the 13' floor/ceiling mode is at a minimum. Alternatively the speakers would have to pulled out from the 21' wall so that the woofer cones(not the back of the M80s)are about 6-7' from the wall, where the 13' width mode is at a minimum. You might want to try the latter move just as a temporary experiment to see what the effect would be.

If speaker placements(or lowering the ceiling)aren't practical, equalization with e.g., BFD is the remaining possibility. Different speakers or a separate sub(assuming that they have strong normal response at that frequency)should have a similar problem, so it's unclear why your other speakers didn't exhibit it.

Yes I have tried using the bass and treble controls on the reciever.I also looked at the manual for the Berenger feedback destroyer.It looks intresting but it doesnt have any rca inputs or outputs.How would I hook it up to my reciever? By the way , why hasn't anyone responded to my original question about the SAE 180 ?

BFD works fine with sub but not recommended for full range speakers. If you really like those M80, then try your best to play with the M80 placement regardless how many furnitures you'll have to move. If that is not possible, then your best option is either buy or build yourself a first order highpass crossover (6dB/Octave), 2nd order(12dB/Octave) is way too steep and cut off too much bass so you dont' want that. Try rolling off point at around 45~60hz(since you said your room has a spike at around 32hz and 40hz), a variable crossover network has better flexibility, do a search for Harrison Labs, their stuff are decent. If you don't feel comfortable messing around with crossover then you better off downgrading your M80 to either M60 or M22ti, they have smaller footprints, less bass, and forgiving on placement. the safest bet is M22ti.

I'm sure if anyone knows about this vintage EQ they will respond.
Unfortunately, I do not have any experience with the SAE 180.

I have never had the 180 but I have had a few older SAE''s and the reason I kind of went around your question is because I never really liked any of them.
