I have the 2.7s and some jl audio e110 subwoofers....but haven't really set them up yet. Been too lazy and the 2.7s sound so good on their own.
I've had the 2.7s back in my system for months (sidelining my JA Perspectives for now) and just love the things.
I'm sooo glad I jumped on this pair of 2.7s a couple years ago. They've become rare as the proverbial hen's teeth, and in my favored ebony finish, this was a unicorn find on the used market.
