BASSBOSS VS21-MK3 Single 21" Powered Active Subwoofer

The VS21-MK3 Single 21" Powered Subwoofer offers low-frequency extension similar to vented dual 18" subwoofers in combination with the hard hitting punch of horn loaded subwoofers. The VS21-MK3 brings the world of extended low frequency together with the world of highimpact: You're no longer forced to choose either deep OR punchy, as the VS21 offers both. The VS21-MK3 is a vented, short horn hybrid sixth order bandpass which features a massive displacement, long excursion 21" woofer, rear-loaded into a large acoustical volume that is tuned to a low frequency, and front-loaded onto a short horn. The vented enclosure section provides extended low frequency performance and the horn section provides increased upper frequency sensitivity and improved transient response.

The VS21-MK3 features a 2500W amplifier with an auto-sensing, globally compatible power supply that can run on mains supplies anywhere between 90 and 250 Volts. Full output power is available on anything over 110V. The amplifier's high peak-output voltage provides for intense high SPL hits while its sustained output is unparalleled in its ability to deliver the liquid lows. The amplifier is passively cooled via its external heat-sink and by woofergenerated air-flow through the port. When necessary, two blower-fans will engage to provide additional forced-air cooling capacity in more extreme conditions.

Features:

• VS21-MK3 Single 21" Powered Sub.
• The "Rum Punch" - so sweet, so deadly.
• The VS21's short-horn allows very high sensitivity in its upper operating range
• It has the effect of increasing the power available for "impact" and "punch".
• The vented part of the cabinet allows it to do the deep notes that 21" woofers do well.
• The resulting impression is one of a very 'big' or 'heavy' hit.
• A high-efficiency 21" woofer is loaded into a large, tuned chamber on one side for deep bass and a short horn on the other for impact.
• The 2500 Watts from the amplifier are put to very good use making SPL and the processing keeps everything safe and smooth.
• There are all-new amplifiers in the MK3 series.
• Total power has increased, however power allocated to woofers increased substantially.
• The higher output voltages provide more impact.
• Universal input voltage compatibility of 90-250V provides more flexibility.
• Waterproof connections provide more peace-of-mind.
• The MK3 features an all-new 96kHz DSP.
• The pushbutton presets have doubled, from 4 to 8, and up to 100 presets 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 supports an essentially unlimited number of possible BASSBOSS-developed or customized user presets which integrate seamlessly and coherently with all other BASSBOSS products for effortlessly perfect setups.
• The latest in DSP programming developments can be added via easy remote updating.
