Product Details

Precision Port Dimpled 4" Flared Port Tube Kit

The 4" dimpled Precision Port™ from Precision Sound Products reduces port turbulence in woofer and subwoofer bass reflex enclosures to unprecedented levels when compared to standard and flared port tubes, as well as slotted ports and vents.

Optimal air flow in a ported or vented enclosure allows for cleaner bass and higher realized output without the chuffing normally associated with run-of-the-mill ports—especially useful when used in high SPL applications.

Precision Sound Products uses high quality ABS construction for each Precision Port, while their injection and extruded molding processes allow for tight, consistent tolerances for proper fit. Create a port up to 18" long, then glue with ABS glue found at any hardware store. I Designed in the U.S.A!

To calculate the proper port length for your cabinet and tuning, use Precision Sound Products' Port Length Calculator.
