As you can probably tell, they didn't have their reflex tubes put in, we forgot those at his workshop. Oh well. Anyway we will get those and put them in on saturday. As for listening impressions, WOW. They are loud and they are deep. Once I get them back home in America and in a proper room, put them on gramma pads, get a proper 4 ohm amp with room optimization and equalization etc etc I am sure the sound will tighten up and be even better. These things could play at ear splitting levels with no hiccups. In the room overhead the guy came downstairs to where we were and told us his remote control was walking across his coffee table.
I tested them out with a bunch of different music I like. Youtube it if you want.

In the last picture you can see 2 smaller towers behind the monster ones we build, those are some he designed and built, with, I think, 12" side firing woofers, in a sealed contruction, and you could immediately tell a difference when we compared. The ones we built for me had a much fuller and complete sound with tighter bass, even without the bass reflex tubes even in. His played loud for sure but they started to hurt your ears at higher volumes whereas mine didn't at all, even in that sub-optimal room with all hard surfaces.
