Kali 15″
3000w XBL2 Car Audio Subwoofer
Kali is the only 4-inch XBL² subwoofer in production. 3000W RMS handled through a 4-inch voice coil that does what 4-inch coils don't usually do — survive the power, dissipate the heat, stay linear across stroke. It exists because nothing else covers the same alignment range.
Sealed, ported, IB, vehicle, home — Kali handles essentially any installation. The application doesn't pick the chassis; the alignment picks itself.

Each chassis is engineered against the same Kali character. Pick the size that fits your alignment; the philosophy is constant.
Kali is the right call when the install demands the most of a single chassis — extreme output, dedicated systems, builds that ask the driver to do everything. The 4-inch coil is the unique element; nothing else in the world ships with one in this topology.
Match amplification to 3000W RMS continuous, not peak-rated.
