"I strongly recommend the Revel Ultima Sub 30." - Stereophile magazine
"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. Any excellent pair of speakers would likely sound better with a properly tuned Revel Ultima SUB 30 in the system." - Home Theater Review
Revel's Ultima SUB 30 in an active subwoofer, packed with a robust 15-inch driver pointed forward, with a 15-inch passive radiator pointing towards the floor. The radiator allows the SUB 30 to breathe better and move a huge volume of air. The driver designed for the Revel Sub 30 is nothing short of incredible, with a huge magnet and a driver excursion of three full inches. Unlike the trendy small subwoofers on the market, Revel chose to put a beefy class AB 1,000-watt power amplifier inside the SUB 30, which gives a heftier, weightier sound to the woofer, compared to the dynamic but not as authoritative output you get from digital (class D) amplifiers found in lesser though expensive subwoofers.
