Capable of delivering 3600W RMS—and 7200W peak—the RCF SUB 9007-AS is an active subwoofer. It provides two 21" neodymium woofers with 4.0" inside-out voice coils, and as such, can deliver low frequencies within live sound applications, such as clubs, ballrooms, and houses of worship.

The unit operates between 25 and 400 Hz, giving you a DSP-controlled input section that allows you to choose among presets and modify delay settings. It can handle over 141 dB SPL, making it an apt choice for reasonably loud environs. XLR connections are provided, and input signals can be either balanced or unbalanced, further expanding the unit's versatility. Ethercon connections allow it to integrate within RCF's RDNet remote control system, allowing you to change settings over a network.  

Controls are offered for Gain, EQ, Crossover, Phase Switch, Cardioid, and Output Delay. The SUB 9007-AS' cabinet is fashioned out of Baltic birch and capped with a steel grille. This unit pairs well with RCF D-Line HDL50-A and HDL-20A array systems.

The CVX Series 21" Powered Subwoofer from Cerwin Vega features 2000W of Class D power with two combo XLR/TRS inputs and three XLR outputs. The angle-fired 21" woofer, with LF extension to 29 Hz, reduces port turbulence without affecting the performance. When multiple subwoofers are being used close together and rear sound rejection is needed, the cardioid mode can increase the forward volume by 6 dB while reducing rear volume by 12 dB. Covered in Cerwin-Vega's durable TourShield finish, the CVX subwoofer is suitable for touring, ballrooms, medium to larger clubs, outdoor venues, houses of worship, rentals, and staging applications.

The KMT21 Mark I 1600W Powered Subwoofer with DSP from K-array is a complete audio system, featuring a 21” powered subwoofer, programmable on-board DSP, and multiple analog and digital inputs & outputs for creating a broad range of speaker configurations. Equipped with a codec that lowers the signal/noise ratio, the KMT21 Mark I Subwoofer comes with a 5 VDC power connector on the rear panel, and enhanced functionality for creating presets. The AES/EBU output is latency-free (thru).

The KMT21 Mark I Subwoofer features an integrated touchscreen that provides intuitive control over the main DSP functions including input/output levels, signal routing, offset delays for subwoofer and speaker output (up to 10 ms, each) and overall system delay (up to 330 ms). All DSP functions, including EQ, can also be remote controlled via software over USB or RS485 (3-pin XLR).

The subwoofer further provides two balanced analog line-level inputs and a two-channel AES/EBU digital input. An integrated Class-D amplifier delivers 2 x 2400W at 4 ohms, with a max THD of 1% (EIAJ test @ 1 kHz). The rear panel features multiple analog and digital outputs, including a Speakon output to connect a wide array of passive speakers including Kobra & Python mid-high modules or KMT21P additional passive subwoofers (sold separately). To optimize performance, the on-board DSP includes presets to drive K-array speakers.

The KMT21 Mark I Subwoofer’s four-corner port configuration provides symmetrical back-loading to the speakers for extended bass response with low distortion. The port configuration also provides incredible structural strength to the cabinet, despite its light weight. Pocket handles and an M20 thread-mount position for attaching mid-high speakers makes it convenient to use and ideal for medium-throw applications in theaters, concert halls, and audio/video installations.

"5 Star...LOVE it...Although the base is there, it is safe to say you aren't going to get the same depth with a speaker half the size even with a magnet that makes this entire device quite heavy which in turn make is a very solid unit....i got this product from b&h because it was the only source I could have got it from to Canada product itself is just great but it's still in it's early stage so hoping for updates soon because it's lacking in some way I got this for home automation and it's doing it's job bery well."
