These top-of-the-line subwoofers deliver exceptionally powerful, yet tight and accurate bass. Their ultra-high performance and efficiency comes from an ultra-lightweight cone and large strontium magnet, and they include a unique venting system for better cooling.


Aerospace Material Cone

The Kevlar-Rohacell cone is made of lighter and stronger material than previous models, for less moving mass and greater efficiency. The underside uses a vented force transfer assembly for added strength, contributing to high SPL and fast, accurate response. This combination of light weight and strength maximises bass output while ensuring durability.


High-Amplitude Multi Roll Surround

In order to handle extra-high SPL, the suspension has to travel far and still maintain control. Most designs sacrifice cone area for a wide surround, or sound quality for a tall surround. The High-Amplitude Multi Roll Surround is formed from injection-moulded multi-roll Santoprene, enabling both a larger cone area for higher SPL and greater cone excursion for better sound quality.

Large Stronium Magnet

A Specially designed, advanced motor structure and extra-large, triple-stacked stronium magnets ensure that these subwoofers are very efficient. In fact, stronium magnets are used in smaller speakers for their efficiency; using large stronium magnets in subwoofers results in extremely high performance.


Easy-Access Terminals

Simple jumpers with solid-insert, gold-plated terminals make it very easy to configure these subwoofers for series or parallel applications.

Dual-woven tinsel leads with terminals on the same side can handle heavy gauge speaker wire.
