Description

James Loudspeaker PP15-M

The James Loudspeaker PP15-M comes standard with a 15” aluminum woofer housed in a black studio enclosure. The standard flextube is 30″ long and 8″ in diameter, but can be shortened to 24″ without affecting the tonal frequency response. A longer flextube can be ordered to allow for different placement options, but cannot be extended beyond 36″ without affecting driver sound.

The basic concept of the Power Pipe is to direct large volumes of air through a relatively small tube that resonates at a tuned frequency of around 35 Hz. This is achieved through the construction of the driver and the closed housing that surrounds it. Because the woofer has been tuned to have its acoustic peak in the frequency range where bass energy is greatest in music and movie soundtracks, the driver can operate within its linear cone excursion range and rely on the bandpass flextube to to simply “amplify” its performance. The speaker consists of aluminum drivers mounted in a sealed enclosure. At the front of each unit is a sealed bandpass port to which the flextube can be attached and from there connected to any number of available ports.
