The dB Technologies Sub 808D Active Subwoofer features an 18" woofer loaded to a bandpass housing and an onboard 800W digital power amp. The speaker is designed to deliver a low-ranging bass foundation to provide the low-end support that 12" and 15" speaker systems need.
Configuring the 808D to be used with top speakers can be done using the built-in digital stereo crossover with switchable cutoff frequency, phase reverse switch, and integrated control features.
The unit's H.E.T housing is made of premium-quality multiply wood with a durable, scratch-resistant coating. Tough, robust plastic side panels provide protection for the housing as well as integrated grips and electrical connectors for handling convenience and safety.
