Vented, short horn hybrid single 21" powered and processed subwoofer. Frequency response +-3dB from 27-100Hz. Maximum continuous sine wave output: 132dB.
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. The VS21 also features a 2400W RMS power amplifier and a comprehensive digital signal processor.
These features bring the benefits of extended low frequency together with the benefits of high-impact. One is no longer forced to choose either deep OR punchy because the VS21 delivers both. 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.
Thanks to these attributes, the VS21 is extremely versatile, able to satisfy the demands of hard-hitting live kick drums as well as the deep, rolling bass of heavy synth tracks or an 808. For those whose demands span a lot of genres, the VS21 has got them all covered, and thanks to the included amplification and processing, it does it all with plug-and-play ease. The VS21 offers output SPL comparable to a bigger double-18" cabinet and allows more output to be focused forward thanks to its smaller frontal area. The VS21 offers deeper response than the vast majority of double 18" cabinets and much deeper performance than similarly sized horn-loaded boxes. It also offers a significantly smoother frequency response than horn-loaded subs but still retains the desirable transient response and punch characteristics of horn-loaded subwoofers.
Amplification and 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 overexcursion damage, allowing the user to get maximum output from the loudspeaker for as long as necessary without concern about overdriving it.
21" Neodymium motor driver with 1700W RMS power handling and 58mm peak-to-peak excursion capability. The woofer's cone is made from a waterproof fiber matrix.
18mm Baltic Birch plywood, assembled using dado joints, screws and adhesives. Stainless steel bolts are used to secure the driver, amplifer and pole socket. The cabinet is finished in an extremely rugged, black polyurethane coating. The driver is protected by a black powdercoated, perforated steel grill. The amplifier is recessed into the back of the cabinet for protection from damage, direct sun and moisture.
A top-mounted pole socket in each VS21 provides for mid-high loudspeakers to be mounted on a straight speaker pole above the subwoofer. The enclosures also feature four large rubber feet on the bottom and four on each side, with corresponding recesses in the opposite side to facilitate interlocking the boxes when stacked. There are two handles on each side and two handles on the top. The amplifier recess is designed to also serve as a handle on the back of the cabinet and the grill is recessed to allow lifting from the front.
The box measures 24" wide by 36" high by 36" deep, making it surprisingly easy to move and manage. This familiar size and shape also allows it to fit into cut-outs made for the many iterations and clones of the Cerwin Vega L-36, offering many venues an option for a massive upgrade in sound quality and quantity without having to modify existing stages and openings.
Easy upgrades are possible for many venues and operators seeking to enhance the sound quality and depth over their old 36"x36"x24" horn-loaded subwoofers. The VS21 provides for a massive upgrade and fits in the same space, allowing for simple drop-in replacement.
For larger events, several arraying options are facilitated. Block arrays, side-by-side arrays and front/back Cardioid arrays (presets available in DSP,) can be deployed securely thanks to the interlocking feet.
4-wheel dolly carts: All carts are supplied with premium quality 4" locking casters. The carts include handle holes and are made with foot pockets so the cabinets remain secure and stable while rolling on the cart. Covers: Heavy-duty padded nylon slip covers protect your investment from damage while in transit.
VS21-RPI Installation version features the amplification mounted in a rack chassis. This version is recommended for installations where the audience may have access to the backs of the cabinets or in situations where electrical supply can't be installed near the speaker location.
VS21-RPF- Installation version features the amplification mounted in a rack chassis with 16 3/8" threaded fly points. This version is required for installations where the subwoofers need to be flown.
