[QUOTE="John Halliburton, post: 89512, member: 8"] Re: Small-ish Home Theater Subwoofer A right angle bend in a port is not a problem. Just did it with a single 8" Dayton sub for my father in law's new office/PC system, using 3" diameter PVC for a 20" long port design. Another possibility, and you'll probably like investigating the science of this segue, use a passive radiator. You could build the port as part of the cabinetry, also incorporating a 90 degree bend around an inside corner. Given the Xmax of those drivers, the understanding that maximum SPL aren't the goal, and the smaller acoustic space the sub will be used, an F3 design hitting close to 40hz and processing in room should be achievable.
