The HyDrive Design
HyDrive speakers feature carefully crafted paper/aluminum hybrid cone drivers. The hybrid makeup delivers an exceptional blend of warmth and attack that can't be attained by traditional all-paper bass speakers. And specific to the HD508, packing four 8" HyDrive speakers into a single cabinet creates a combined cone area that is larger, as well as able to reproduce a wider audio range, than that of a single 15" speaker.
Power and Portability
In addition to the impeccable sound of the HyDrive speakers, the HD508 offers tremendous power in a highly portable design. Its lightweight Class D amplifier produces an earth-shattering 500 watts of power capable of filling any rehearsal room, recording studio or performance venue. And with a total weight of only 49 pounds, the HD508 is easy to transport with its molded strap handle, metal side handles, or removable casters.
Shape Your Tone
The HD508 includes a selectable Shape circuit that allows you to dial in a specialized EQ curve designed to improve tone by selectively boosting and cutting across the frequency range. In addition, a 3-band EQ provides further customization options.
