High
Intensity
Hits
Versatility that covers every genre, with massive punch and plenty of heft. Excellent transient response is delivered by the efficient performance of the horn at the upper end of the subwoofer range.
The resulting impression is a very big, heavy hit. Extended depth is delivered by the large acoustical volume, low tuning and the massive displacement of the long-excursion 21″ woofer.

Design
The design brief for the VS21 was to create a product that offered low-frequency extension similar to the BASSBOSS vented dual 18” subwoofers in combination with the hard-hitting punch of the BASSBOSS hornloaded subwoofers.
The VS21 brings the world of extended low frequency together with the world of high impact. You’re no longer forced to choose either deep OR punchy, the VS21 offers both.
Versatility
The VS21 is particularly versatile, able to satisfy the demands of hard-hitting live kick drums to the deep, rolling bass of an 808. For those whose shows span a lot of genres, the VS21 has got them all covered.
The same size and shape as the Cerwin Vega L-36, the VS21 will deliver considerably much more output and deep bass. The VS21 is a vented, short horn hybrid single 21” powered and processed subwoofer. Frequency response ±3dB from 25-90Hz. Maximum continuous sine wave output 132dB.
Features
The VS21 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.

Benefits
These features bring the benefits of extended low frequency together with the benefits of high-impact. Excellent transient response is delivered by the efficient performance of the horn at the upper end of the subwoofer range.
Extended depth is delivered by the large acoustical volume, low tuning and the massive displacement of the long excursion 21” woofer.
The combination provides an immediate hit with the added power of full and effortless low end extension. The resulting impression is one of a very ‘big’ or ‘heavy’ hit.
Processing
Powered by a 2400W RMS amplifier, the VS21 includes all the necessary electronics to allow it to be connected directly to your mixer with nothing but signal cable in between. The built-in processing is minimal and includes a low-pass filter that provides a broad, flat frequency response.
There is no need for any EQ in the signal. In addition, a sophisticated limiter system protects the woofer from thermal and over-excursion damage, allowing the user to get maximum output from the loudspeaker for as long as necessary without concern about overdriving it.
