Mark Bass Standard 108HR The legendary 8x10 bass speaker cabinet was always the heaviest piece of gear a band ever had to carry. However, technology developed by Markbass, has brought forth a new era of lightweight bass gear. And best of all, the heaviness of the sound has not been sacrificed along the way. The Markbass 108HR speaker cabinet weighs in just under 90lbs, an unbelievably light weight for an 8x10 bass enclosure. With a monstrous 1600 watts of power handling, this bass speaker cabinet can get as loud as you need it. The cabinet is rear-ported, offering a bass tone that swells with warmth and boldness, while the Markbass 108HR's compression driver with custom horn keeps your tone beautifully defined.
