Description

That is a Hartke HD508, a powerful and highly regarded bass combo amplifier. It’s known for being surprisingly portable despite its "punch," thanks largely to Hartke's unique speaker technology.The "magic" of this amp is in the four 8-inch speakers. They use a hybrid design—the inner cone is aluminum (for "snap" and clarity) and the outer cone is paper (for warmth and low-end "thump").delivers 500 watts of Class D power, which is plenty for rehearsals, club gigs, and even larger stages when used with a PA system.Even though it looks like a mini-fridge, it weighs about 49 lbs (22 kg). For a 4x8 configuration, that is very manageable for a single person to carry.
