I had a set of D-9 years ago and I miss them. Heavy as heck (almost 100#) and took up a ton of floor space. My ex hated them because they would thump her "stuff" off the wall shelves!!!!
I still have two pairs of the D9's, had them re-foamed and re-glued the cabinet. I have pair in my bed room hooked up to a Harman Kardon 120 wpc receiver and in my TV room I have pair of D9's with a 130 wpc Kenwood amp. When I crank them up something will fall off from some where in the house and I usually get yelled at by my wife for breaking something . Just like the GNs, I am a junkie for the old school Cerwin Vegas. I also have 3 pairs of the AT12 in other rooms as well a pair AT8's in the kitchen over the cabinets.
Any way back to the topic, the garage looks awesome!!! maybe you may want to get the floor coated before your Buick stains it. You know they are not potty trained.
