It pairs that frame with a quad-stacked 265mm (10.43″) motor and a 100mm (3.94″) magnet stack — the largest motor ever used on a Z series sub — driving a 3.3″ 4-layer round-wire aluminum voice coil with a 95mm winding length. A patent-pending airflow-directing pole cap, six pole-OD channels, sixteen gap vents, and a cross-drilled top plate keep the coil cool, while a 9mm magnet-ID Faraday ring and pole-extension inductance sleeve deliver highly linear inductance. The result is 42mm of one-way linear excursion by 70% BL with an extremely uniform curve, designed for the lowest bass extension possible in a small ported enclosure with very low distortion.

Its 2.75\" aluminum-former coil punches above its weight, outperforming many 3\" coils without the added mass while allowing a wider spider. A large magnet shorting (Faraday) ring reduces distortion for smoother response across the spectrum, and a vented magnetic gap and pole piece keep the coil cool. The motor and coil mate to a robust multi-layer spider with doubled-up XL tinsel leads, a competition-grade paper cone, strong foam surround, and cast-aluminum frame.
