The Revel Ultima SUB 30 is one of the finest subwoofers money can buy. It has engineering and design behind it that most other speakers companies can only dream of affording. With the Revel Ultima SUB 30, all of the engineering, testing and development deliver you an expensive subwoofer that can rock your world for movie soundtracks with power and add the lowest register of bass to any audiophile speaker system with finesse.
The Ultima Sub 30 ($5990) is a powered subwoofer with an active 15″ driver firing forward and a passive 15″ radiator facing downward, both sharing the same inner enclosure. Kevin Voecks explained that the passive radiator acts like a port, but without any of a reflex port’s chuffing noise. The 15″ woofer uses a 4.7kg magnet, two copper voice-coils, and two spiders. The driver has one of the longest peak-peak excursions I’ve encountered in a subwoofer: 3″. The true linear volume displacement is 275 cubic inches. Both drivers are set into a slightly flared cabinet wider at the front than at the rear, close to 2′ on a side, and weighing 145 lbs.
