PWR Cone Design: This BassLine subwoofer's patent-pending
Progressive Wavelet Ribs (PWR) cone design helps break up standing waves and
cone resonances to keep distortion low. The sub uses a polypropylene and mica
damped cone assembly and a high-excursion poly-foam surround.
Progressive Polyester Spider: The progressive polyester spider
provides accurate control of the subwoofer cone motion.
Two-Piece Yoke: The two-piece yoke uses a vented pole to
provide improved air flow and help cool the voice coil.
Spring Terminals: The spring post terminals accept pin
connectors, single or dual banana plugs, or bare wire up to 8 gauge.
Sealed Box Volume: The recommended sealed box volume range
is from 0.75 cubic feet to 1.5 cubic feet, with 1.09 cubic feet being the ideal
Ported Box Volume: The recommended ported box volume range is
from 1.5 cubic feet to 2.5 cubic feet. The ideal size is 1.91 cubic feet, using
a slot port measuring 12-1/2" (W) x 1" (H) x 10" (L).
