Hartke HD508 Hydrive Bass Combo Amplifier - 500W, 4x8"

Hartke HD508 500W 4x8" Bass Combo Amplifier — High-Velocity Punch & Massive Surface Area

Deliver articulate, high-output low-end performance with the Hartke HD508 Bass Combo Amplifier. Driven by an efficient 500-Watt Class D power amplifier, this flagship combo features four 8" patented HyDrive hybrid cone speakers. The 4x8 configuration creates a combined surface area larger than a single 15" speaker, offering deep bass response alongside lightning-fast transient response.

Weighing 49 lbs (22.2 kg), the HD508 is built for gigging musicians needing stage volume without bulky 4x10 cabinets. It includes steel-reinforced side handles, a top strap handle, and removable casters for easy transport. The top control panel features Hartke's Shape EQ—a variable notch filter (100 Hz – 900 Hz) that applies a targeted EQ curve to cut or boost frequencies instantly.
