I'll go ahead and bump this thread, because I had the chance to see (and HEAR!) these beauties last weekend. Craig (cuzed) was kind enough to have me over to his house to check out his theater. His setup, and especially the SEOS mains, really impressed me.
I'll keep this short, but my biggest takeaways were these:
High sensitivity means DYNAMICS! The peaks, even in content I know well, are so much bigger than I ever experience them at home.
But at the same time they're incredibly clean. Loud crashing glass on my speakers at home makes my ears hurt. Loud crashing glass at Craig's house sounds like loud crashing glass.
The Duratex finish really looks good. I'd never seen it in person before, and I was surprised how professional looking a speaker it makes. Between the finish, the nice looking grills, and the cool 3D logos he's made, Craig's L and R easily pass for commercially produced speakers.
The blending between the BUC and the L and R was perfect as far as I could tell.
Sitting way off to the sides sounds nearly the same as sitting right in the sweet spot. I've never experienced that before. It was actually a bit weird, as when I sit off to the left my mind expects to hear nothing but the left speaker. Not here. The image stayed almost dead center. I loved it.
Spending time in a real home theater makes me appreciate how much room I really have for improvement in my own setup. I really want a bigger screen now. The attention to detail visible in those speakers and in the entire room is really extraordinary.
I'll definitely be building some SEOS mains. The cleanness and loudness of the peaks in soundtracks is what sells me on them. Between that and the rock solid image from seat to seat, I can't see ever going to low efficiency, omnidirectional speakers for home theater again. I was initially a little concerned about horns. The only time I've really listened to horns before was with some fairly inexpensive Klipsch speakers. I heard a lot of honk in them, and I really didn't like them for it. I was listening specifically for that during this session, and I never heard even a hint of it. We listened to a wide selection of music, thinking it'd be a little more revealing. They still sounded great.
Thanks again to Craig and his family for inviting me into their home. And thanks for the good beer and the great conversation. I look forward to seeing you again. Next time I'll host, and you can give a listen to whatever SEOS designs I end up building!
