Great price for amazing subs!

By CHRIS B.

Amazing subs that pack a nice pinch, but also deliver a great even low range wave.

It's time to redefine your audio experience with the SUB 918 Active Subwoofer, a high-quality, stylish, and durable audio equipment that delivers powerful and reliable sound. This 18" active subwoofer is expertly designed by dB Technologies to provide complete control of low-end power, ensuring a deep, full-bodied sound across a variety of applications.

The SUB 918 is equipped with a single 18" premium woofer, housed in a bass-reflex design, that is capable of producing forcible sound pressure levels up to 134 dB. This is made possible by a 900 W RMS Class D Digipro G3 power amplifier, which guarantees advanced efficiency.

This active subwoofer is not just about power; it's also about control. It's ready for full remote control via RDNet and Aurora Net software, available for both Windows and Mac. This allows for real-time monitoring and remote control, enabling advanced subwoofer configurations and perfect low-end matches with dB Technologies' full-range systems enabled for RDNet communications.

On-board controls for attenuation, a polarity switch, and DSP controls for a delay up to 4.5 milliseconds with 0.5 milliseconds steps are also featured, with a maximum 21 ms delay allowed via Aurora Net. A second rotary allows you to set the crossover frequency from 70 to 110 Hz, giving you even more control over your sound.

The SUB 918 is housed in a robust plywood cabinet that combines high-end performance with limited weight, making it easy to transport. It features two integrated handles on the top edges and wheels on the back for smooth transportation. Designed for both vertical and horizontal use, it also includes 2 M20 mounts on the top and side panels for any type of full-range speaker led using a standard M20 threaded pole.

The SUB 918 Active Subwoofer is more than just a subwoofer; it's a testament to the power of sound, designed to deliver a deep, full-bodied audio experience that will transform your professional audio and video applications.
