Does the rear port deflector on most of Polk's speakers ( you know, the big plastic square attached to the back, shaped like a funnel on the inside where it exits the port) serve any useful purpose (sonically speaking) if your speakers are placed so they're nowhere near a back wall?
Theoretically speaking, I can't see a benefit to having this in place unless speaker placement is an issue.
Has anybody out there in Polkland ever removed it and, if so, what was the result - good or bad?

    It is designed to reduce the turbulance of the air and the associated "chuffing' sound that can accompany it. Leave it on.

    Don't remove it. That's a power port, you can read about it on this site. It prevents port noise and increases bass by 3db.

    Thanks,
    I knew that flared ports offer those exact benefits you described. Although it doesn't look like a traditional flare, I guess that "power port" offers the same benefits.
