W7 13.5-inch Subwoofer Driver (1500 W, Dual 1.5 Ω voice coils)
Words like "extreme," "reference" and "ultimate" get thrown around
quite a bit in the subwoofer driver world, but rare is the product that
can honestly lay claim to them. The 13W7 does.
Taking the W7 design formula to its highest level, the 13W7 offers a
staggering linear excursion envelope that exceeds 1.25 inches (32 mm)
one-way, along with a suspension capable of over 4-inches of
peak-to-peak excursion. Combine that with a piston diameter that is 28%
larger than the 12W7's, and you have a serious high-performance driver
for the most demanding applications. With a 13W7, limits simply vanish
and amazing sub-bass happens... on all fronts, at any level.
