Just a little update on my search here. I was able to demo a full "one's" system at the Natick Ma headquarters on Friday last week. The setup was a trio of the 8351b+w371 and then 8341s for surround and height channels. The guys at Genelec were great. They let me run the controls and choose whatever tracks and clips I wanted to hear. The downside on clips is that the projector wasn't running, so I'd be hearing the soundtrack and looking at a tiny image on the computer screen....it does take away from the experience, however the sound was still great. With music imaging was outstanding and I found nothing forward or fatiguing in the least bit....the sound characteristics were very much to my liking, with one exception. I felt everything sounded a bit thin on the bottom(maybe 200+/- hz on down. They were bass managing with a 15" of their subs and it was certainly limited (I'm a bit of a basshead), but that wasn't what concerned me, it was that 200 or so hz range down to 80hz I said above. There wasn't a real weight to it in most tracks, no physical hit to the chest by the kickdrum, no string plucks that you really "felt". Initially it had me concerned, but I'm thinking more and more that I was listening to cuts from producers that were fairly flat, in a room that is extremely flat and maybe it's just that. "Thanks to You" was one of the only songs that I felt real weight in. The image was huge and enveloping and made me grin for sure. I was very clear with the guys about how I felt something lacking in the woofer stands range of frequencies. They are working on a demo for me to hear the 1234A now and see how that goes. We talked at length about my room, my needs and preferences, etc. and they say that at the distances I'll be in either row (somewhere between 12 and 20 respectively, pending final room design) I'll get all the attributes of the "ones", but with much more output and attack. They did recommend the AC version which is stacked vertically as well. Their thought was that the 1234AC could have all the output needed all the way down to 35-40hz, and then I'd cross to the 24s for the ULF, keeping it simpler than running multiple subs at different ranges. I'm not apposed to doing that still, but only if need be, and it would probably be the NSW sealed from 40-120 rather than a horn, just because of form factor. This post is sort of all over, but wanted to give my impressions and thoughts and also see what you all think of my observations of the "thin" sound in the midbass.
