Sweet, Strong, and Intoxicating - The BassBoss VS21-MK3 21-Inch Two-Way Active Powered Subwoofer

The VS21-MK3 features punchy and full deep bass, very high output SPL, smooth even bass, accuracy, and versatility across all genres—from Dubstep to acoustic performances, this sub has you covered. This self-powered unit includes the BassBoss comprehensive DSP suite.


  • Black finish
  • Ideal for shows spanning genres that need intense dance-floor coverage
  • Transient response is delivered by the efficient performance of the horn at the upper end of the subwoofer range
  • Extended depth via the large acoustical volume, low tuning and the massive displacement of the long-excursion 21-inch woofer
  • Brings the world of extended low frequency together with the world of high impact
  • Satisfies the demands of hard-hitting live kick drums to the deep, rolling bass of an 808
  • Delivers considerably much more output and deep bass
  • Massive displacement, long excursion 21-inch woofer, rear-loaded into a large acoustical volume that is tuned to a low frequency, and front-loaded onto a short horn
