RBH MS8.1: Sometimes The Truth Comes In Small Packages

Instead of designing a run of the mill 8-inch subwoofer to accompany the CT speaker line, RBH decided to take it to the next level and create a subwoofer that has more output capability than you would expect a subwoofer paired with a “mini” system would!

  • The MS-8.1 features not one, but two 8-inch aluminum drivers and an internal 200-watt amplifier.
  • It delivers an impressive bass down to 35 hz

It uses two 8″ aluminum-cone drivers — one front-firing, the other down-firing — with a 200W amplifier in a side-ported, medium-density-fiberboard cabinet measuring 13″ high, 11″ wide, and almost 14″ deep. It has 5 way binding posts (not the cheap spring clips you see on other subs) for its speaker-level connections, a variable crossover from 40Hz to 160Hz for line-level connections, variable phase control, a 230V/115V switch, detachable power cord, dual inputs and outputs, and a heatsink on the rear panel.Try picking this thing up- it weighs a solid 35lbs!
