Full Description

Remarkable Audio Performance

Impressively precise low-end reproduction. Featuring a 600W RMS Class-D power amplifier with SMPS, the dB Technologies SUB 612 Active Subwoofer delivers outstanding sound pressure levels. Reaching 129dB, it provides optimal definition and sound reproduction, resulting in hard-hitting bass that stays true to your source audio. It's ideal for a range of applications, from live performances for musicians and DJs, to houses of worship and more.

Clever Design

Use with ease and accuracy. The control panel features a polarity inversion switch for calibrating your sound for optimised audio performance. Need that extra punch? The Sub BOOST mode switch will provide an extra burst of those sultry low frequencies. You can also choose to operate the SUB 612 in mono or stereo mode, as well as including Link or x-Over balanced stereo output modes.

The bass-reflex design provides added clarity to the bottom-end response. It is ideal as the basis for any PA system, ideal for use when configured with 2 full range speakers. The X-Over signal mode is designed to feed both left and right speakers, eliminating any external processing or crossover for added convenience.

Robust Enclosure

Sturdy and lightweight. The physicality of the SUB 612 provides a strong, durable cabinet that can be transported and set up easily. Its compact size is perfect for portability but doesn't compromise on the sound quality at all. The enclosure itself is constructed from premium-grade wood, finished with a scratch-resistant black covering for optimal durability. Stacking is made easy by the design of the top side, also featuring a M20 pole mount thread for stacking full-range speakers.
