your right i errored in what i said, speakers were set to small ,x- over set to 80hz. however i definitly get a boost in the very lowest bass if i set the ep500 to 80hz instead of bypass.
If memory serves my old yamaha never gave me bass this deep when the ep500 was set to bypass, i dont think i ever tried the 80hz on the ep500 , with yamaha.
Keep in mind the bass sounds fantastic both ways , i just get a little boost to the lower end when i set the ep500 to 80hz instead of bypass.
I would be interested if anyone else gets this boost as well.
