I wonder if given a side by side choice people would go with something the the Venue instead?
I'd love a pair of Venues, but I'd need to have them at least 3' from the wall and to answer Eric, my 11x14x8 room isn't large enough.
This is the reason I couldn't sleep last night

But I understand they wont go into production.
You could definitely run open baffles less than that from the wall in a room your size with proper trapping behind them.
They also wouldn't load the room like the LS series line arrays. The volume of the ports of the LS line arrays really benefits from a room with more geometric volume. As far as ported speakers go, Danny is great at getting the porting just right that his speakers don't overload a decent sized room (with proper placement and room treatment ) and won't be bottom shy in a large room. I've run the LS-9's in 36000 cubic ft, with no loss of low end whatsoever.
The other aspect is, you won't get as much low end extension with that short a line of woofers, and would more than likely want to run a sub.
The Venue would win in out in your scenario again.
Cheers
