Delivering outstanding low-frequency performance, the 720-watt NX720S powered subwoofer has been designed from the ground up to be the ideal companion for any medium sized live sound or DJ PA. Although it is the perfect match for the NX55P it will match well to many other system. Intended for a variety of applications, the NX720P uses a single long excursion neodymium magnet 15-inch woofer to deliver maximum output over the entire 40 to 150 Hz range.

The NX720S has sophisticated processing circuitry that protects the driver while maximizing the use of the available power. This processing has been carefully optimized to complement the characteristics of the driver and enclosure system. The fast limiter protects against clipping and over excursion. It is located with both high and low pass filters on either side of the limiter to guarantee that only the correct frequency content reaches the driver. The slow (RMS) limiter is equalized to adjust for the impedance variations of the loudspeaker system over frequency. This ensures the maximum output of continuous bass prevalent in today's music while ensuring protection of the driver against overheating. The carefully tailored attack and release times ensure that the maximum level is available from the system.

The input section in the NX720S allows for a variety of system configurations. There are two input sections allowing two signals to be blended into the NX720S. This allows stereo left and right signals to be summed into one NX720S while preserving channel separation of the stereo signals. Each input section has XLR male and female jacks to allow loop thru of line level signals. In addition one input section also has two 1/4-inch jacks that may be used for loop thru of line or speaker level signals. Within each section all jacks are connected in parallel.

Simple controls on the NX720S include an input gain control (Volume), variable high frequency cut-off and low-frequency tunable bass boost. The variable high frequency cutoff is adjustable from 90 to 150 Hz to trim the subwoofers low-pass filter to suit whatever full range cabinets are being used with this sub. A low-frequency tunable bass boost adjustable from 45 to 90 Hz has been included to allow subtle customizing of the bass character.

Proven Class D amplifier technology allows the NX720S to operate without a fan while preserving ample thermal margin. The low heat dissipation of this technology eliminates the need for large heavy heat sinks. The light weight neodymium driver further reduces the overall weight.

The NX720S uses a solid 5/8th-inch 11-ply Russian birch plywood cabinet construction with an all-metal heavy gauge perforated grille to protect the speaker and electronic components. Integrated all metal bar handles and metal speaker-stand pole-mount have been included.
