Can anything useful be done with Eminence Omega 15"? I have 4 of these drivers. Thanks and sorry about OT.

Samuel, I think if it is for home, a 6th order design is in order if you are willing to make a Q=2 filter for it. Omega 15" tuned to 27hz should hit xmax at 140 watts per driver around 40hz.

I'd ask this in its own thread here on the sub forum.

Thanks Norman; I would have started a dedicated thread but 40Hz is a bit too high for my liking for HT or Music.

40hz a bit too high ?

That's not the F3, that is the max excursion frequency b4 the driver skips out of its xmax.

F3 of 27hz is fine, but it requires a boost circuit (for that driver). That driver isn't the deepest when run as a sealed or a normal 4th order subwoofer (or ebs either).
