James Loudspeaker® Powerpipe Series 12" Marine Subwoofer

At a Glance

The basic design behind the Power Pipe is to move large amounts of air through a relatively small hose, which resonates at a tuned frequency of about 35Hz. This is achieved through the design of the driver and surrounding sealed cabinet composition.

Proposition 65 Warning for California Residents

The basic design behind the Power Pipe is to move large amounts of air through a relatively small hose, which resonates at a tuned frequency of about 35Hz. This is achieved through the design of the driver and surrounding sealed cabinet composition. Because the woofer has been tuned with its acoustical peak in the region of frequencies where bass energy in music and movie soundtracks tend to be greatest, the driver can operate at the frequencies within its linear cone excursion range, and rely on the band pass flex tube to simply “amplify” its output. Features all aluminum drivers mounted inside a sealed enclosure. The front of each unit features a sealed band pass port, where the flex tube attaches and from there connects to any number of available port options.
