Uncommon hands-on controls
Nearly all powered subwoofers give you level and crossover adjustments. But a scarce few provide any real hands-on control of the sound beyond that. That's because sophisticated EQ and slope adjustments are difficult and expensive to implement. Revel considers these an essential part of the subwoofer experience.
On the B1's back panel you'll find parametric room equalization controls that let you fine-tune the sound for your system and for your room. The really cool part? You get free lifetime tech support with your sub purchase from Crutchfield, so we can help you dial things in to get the best sound.
The B1 features parametric room equalization controls that let you fine-tune your subwoofer's sound.
Built from high-quality materials for great sound
The B1 sports a 12" front-firing woofer that's composed of micro ceramic composite (MCC), which means it's very strong and stiff, but also lightweight. This lets the woofer produce accurate, uncolored low frequencies that blend in seamlessly with the other speakers in your system.
This sub gets its juice from a built-in 250-watt amplifier, which delivers high-output power at low distortion levels.
Tested by instrument and by ear
Revel's world-class speaker design and testing facility features an anechoic chamber and the latest high-tech measurement gear. But some of their most critical test instruments are the ears of their trained listening panel. When working on a new design, Revel's engineers set up a series of controlled auditions comparing their design to several competing speakers.
Speakers under comparison sit on a rotating platform, and each model is moved into the identical position by a computer-controlled belt drive system. An acoustically transparent screen hides the speakers from the listeners to avoid visual bias. These double-blind listening tests provide an essential reality check, and help the engineers correlate measurements with what listeners actually hear and prefer.
