Hartke's popular HD Series now features the high-powered, lightweight HD500 Bass Combo. Packing two 10" Hartke patented HyDrive speakers with rare earth neodymium magnets and a 500-watt Class D amplifier into a sleek enclosure weighing only 35 pounds, the HD500 provides exceptional bass tone to any rehearsal, stage or studio. 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. The use of rare earth neodymium magnets also helps to maintain lightweight portability without sacrificing any of the legendary Hartke attack. Beyond the impeccable tone of the HyDrive speakers, the HD500 offers tremendous power in a highly-portable design. Its lightweight Class D amplifier produces an earth shaking 500 watts of power capable of filling any rehearsal space, recording studio or performance venue. And weighing just 35 pounds in all, the HD500 can be easily transported via a molded strap carry handle anywhere that needs more bass. A result of Hartke's many years of involvement in the bass community, the HD500 includes a selectable Shape control. This feature activates a specialized preset EQ curve designed to improve your tone through selective boosts and attenuations across the frequency range. The adjacent Shape variable filter, as well as a 3-band EQ, provides further customization.
