Our room is on the long & narrow side but I have maybe 25-30' between the KHorns on the other end. Sealed or front ported enclosures, huh? I'll have to do some more reading but that sounds do-able. As for a receiver, I don't have anything besides the TV right now. Would that be recommended? You mean, vs. an amp, etc. (sorry). Radio listening might be nice when Brent Musberger is doing the game. Need to mute him somehow!
