I did, 80 hz seems (for now to my ears) work very well. I decided to let the Model T's be T's and not round them out. I am letting the EP500 be the sub and not try to be a T. I noticed the difference from the office in the house; the floor was beating to Timo Maas.

And this is not speaker break-in which I don't believe in. It's me getting used to the subtle sounds after two days.
