•Dual 2 ohm, 2-layer copper voice coils

•Large vented pole piece and under-spider venting

•Black anodized aluminum former and black pole improves heat dissipation

•Thick, one-piece Nomex honeycomb covered cone with woven heavy-duty glass-fiber

•Tall-boy rubber surround for extra-long linear excursion without reducing cone surface area

•Dual linear stiffness spiders limit distortion and rocking modes

•Copper shorting rings and cap reduce distortion due to inductance variations

Cabinet recommendations:

• Sealed 3.1 cubic ft. (net internal) with 1 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment

• Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4" diameter by 26" long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible. The largest recommended cabinet is 10.5 cubic feet tuned to 16 Hz using two 4" diameter ports that are 21" long for an f3 of 19 Hz.

Note: All parameters derived with voice coils wired in series.
