Subwoofer for Big Theaters

There comes a time when you need more subwoofer in your theater room. If you have a large dedicated theater a single small sub will not cut it. The RBH Sound Unrivaled 221 Subwoofer System has two 21″ carbon fiber subwoofers. It’s built to be used in a large system that requires serious bass output.

The Unrivaled 221 can be configured with one or two amplifiers. This allows you to determine how much amplification you want for your system. You can also choose from Piano Black, High Gloss White and custom finishes to complement your finished theater.

Drivers and Cabinet

Both of the 21″ drivers are made of carbon fiber which is very rigid yet light. These drivers are built to reach extreme excursion. With two drivers pushing air there is no strain on any one driver.

RBH has built their enclosure using CNC and a lot of bracing to keep cabinet resonation at a minimum. This will allow you to hear what the drivers are putting out and not your cabinet rattle. Also, the RBH Sound Unrivaled 221 Subwoofer can handle up to 12,000 watts RMS and 24,000 watts peak. Giving you plenty of head room if you decide to add more amps to your system.
