Okay, so I've got a couple Polk dx9's (3-way coax's) sitting around that I took out of my car a couple years back, and have no intention of ever using them in the car again. However, while they were in, I was really impressed with their clarity and efficiency, especially with vocals and spoken voice. So I'm thinking I could build a pretty nice center channel out of them for my home setup for real cheap (read: free). Recommended RMS (at 4ohms) to run them is 5-55 watts, which once they're wired up in series to create an 8 ohm load will match well with the power my receiver puts out. I'll obviously need to fine-tune the gain so it doesn't overpower my sides or satellites, but that's no biggie. My question is - what sort of enclosure would work best for them? Am I gonna need lots of airspace? Or would just propping them up in a baffle work? They sounded great just plopped in the rear deck of the car w/ some XTC foam baffles, but I'm not sure what direction to go for a center channel application. Having a tough time finding t/s parameters for them as well, which isn't helping. Any ideas? Thanks in advance . . . .
