BASSBOSS VS21-MK3 2500W Single 21-Inch Powered Hybrid Subwoofer

BASSBOSS: The Perfect Solution for Your Performance Needs
The BASSBOSS VS21-MK3 2500W Single 21-Inch Powered Hybrid Subwoofer provides a wide range of shows and genres, delivering hard-hitting live kicks and the rolling bass of an 808. The VS21 model is the perfect blend of performance and versatility, providing precise low-end reproduction with massive punch and plenty of heft.

Give It a Punch
Are you looking for the output of a double-18” sub from half the power and less space? The VS21's short-horn allows very high sensitivity in its upper operating range, resulting in increased power available for “impact” and “punch.” The vented part of the cabinet allows it to do the deep notes that 21” woofers do well, providing an impressive, “big” or “heavy” hit.

Dangerously Sweet
The high-efficiency 21” woofer loaded into a large, tuned chamber on one side for deep bass and a short horn on the other for impact, makes the VS21 a perfect combination of power and subtlety. The 2500 Watts from the amplifier are put to good use making SPL, while the processing keeps everything safe and smooth.

MK3 Amp Update
The MK3 series comes with all-new amplifiers. The total power has increased, with power allocated to woofers increasing substantially. The higher output voltages provide more impact, and universal input voltage compatibility of 90-250V provides more flexibility. Waterproof connections provide more peace of mind to users.

MK3 Enhanced DSP
The all-new 96kHz DSP on the MK3 features 8 pushbutton presets, with up to 100 presets that can now be stored in the DSP and loaded via LAN. The comprehensive suite of processing includes meticulously tuned equalization, all necessary high-pass and low-pass filters, as well as multiple protection systems and limiters to prevent driver overload in as many ways as possible.

ControlBASS Software
ControlBASS software supports an unlimited number of possible BASSBOSS-developed or customized user presets, which integrate seamlessly and coherently with all other BASSBOSS products. The latest in DSP programming developments can be added via easy remote updating, providing users with a hassle-free experience.
