I am loving it. Just received my rythmic F15 sub two days ago. Have it blended pretty good, but will continue to tweak. It is an amazing sub and with eyes closed it cannot be located. Last night I pulled out a couple of old CD's, Larry Carlton and also A tribute to Jeff (Picarro)by Sheffield Lab, listening in stereo at about -10. Night before was Dave Matthews and Tim Reynolds at Radio City BD. Axiom was right, dust off the old CD's. I have a bunch to pull out that I haven't listend to in years.
