If it truly is 16" then you are golden. The rear ports on my Signature C5 center speaker are only 12" away from my front wall.....but I also have 6" thick bass absorbing panels between the speaker and the wall also
















. I've been a fan of the Paradigm sound for years (have Studio 60's) and auditioning other brand satellite HT speakers recently reinforced that fandom. I'm looking to get the MilleniaOne, but I've run into a snag. They're expensive, barely within my budget.
