Features and Specifications:

The Ultimo was engineered to set new standards in subwoofer technology and bass performance, satisfying the most demanding car audio enthusiasts. Available in a single voice coil configuration, the Ultimo subwoofer series is engineered to perform well in both sealed and ported enclosures, offering the flexibility of a wide range of applications.

Equipped with a gigantic 5.1 Hexatech External Voice coil, and constructed of a heavy gauge high temperature aluminum wire and an extra thick aluminum former, the Ultimo subwoofer produces 1000WRMS (3000W peak) clean power output. The new DMM motor design achieves over 90% efficiency and the PFS spider/surround technology ensures maximum linearity, minimum distortion, and truly flat response.

The Ultimo subwoofer employs a unique hybrid paper-carbon fiber composite cone that generates an extraordinary combination of musicality and sound pressure both in SQ and SPL applications.

The high venting capability of the voice coil and the rigid Uniflow die-cast aluminum basket design provide reliable and stable operation of the subwoofer enabling many hours of listening enjoyment.

Morels new, top-of-the-line subwoofer was a long time in coming, but it was well worth the wait. Spoil yourself, and hear how bass was meant to sound.
