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 drivers design 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 flextube 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 flextube attaches and from there connects to any number of available port options. As each of the Power Pipe subwoofers are passive, they can all be powered by James Loudspeaker's M1000 DSP amplifier, providing up to 1000W of power. The PP15-M comes standard with a 15" aluminum woofer, housed inside a studio black cabinet. The standard flextube is 30" long and 8" in diameter, but can be cut down to 24" without it affecting the tonal frequency range.
