4" Racetrack PowerPipe Port - Straight Entry Through Design

Technology header click

Straight back mounting adaptor, for 2X4 or 2X6 wall construction, works with all PowerPipe subwoofers, except the 1500PTM. The tube size is 4" and has a 180 degree entry. Unit features a 3" x 14" in-room opening and a 10.25" (260mm) clearance from flange edge to tube - generally used for behind wall mounting.

NOTE: The round pipe/tube must be physically deformed and forced to fit the elliptical flange and can be difficult to seal air tight.  We suggest you use the TKAD-4-E adapter if you have the avilable depth.
