Chess,
I never said matching the XO frequencies would not work, but it's pointless if your receiver is setting the crossover anyway. You could set the sub's XO at 40, and it would not matter if the receiver's XO was set at 80. There would be a hole in between those frequencies. Do it the other way, then you get double duty.
Why not just set the sub XO as high as it will go and do it all through the receiver?
Well for one my receiver only has an 80Hz x-over.
Bought it back in 2002 and it is only a 6 ch unit.
Are you trying to tell me i need to get something newer?!!
Anyway, it really was not so much my point as that the sub is built for low frequencies, and is much better, and MUCH more efficient at doing it. The M80 is GREAT, but it is no match for the EP500 for frequencies less than 80Hz.
Efficient yes but more boomy IMO.
I've compared the sound of subs in the 'higher' low bass range and they sound less accurate, less tight. I prefer the bass from a smaller driver especially for music.
I set the sub to only play the very low end that really is beyond the capability of the mains.
