So how much room does the LS Center need behind it to work properly? For those too close to a wall, can the LS Center be designed with a sealed option, or is an N3S the best way to go in that case?
BTW, I'm using an X-Voce center with my LS-6's, and built and use a pair of N3S speakers as side surrounds. I actually like my X-Voce, but could always use a new project to do if I can improve my system.
