About dB Technologies SUB 618

With its robust and compact design, the SUB 618 Active Bass-Reflex Subwoofer delivers an impressive sound experience. This high-quality subwoofer is powered by a 600W RMS Class D Power Amplifier with SMPS, ensuring powerful and efficient performance. The 18" transducer, larger than many on the market, guarantees a wider frequency response and precise low-end reproduction, providing an outstanding sound pressure level of up to 133 dB.

The SUB 618 is not just powerful, but also versatile. Its superior audio performance allows for the construction of comprehensive PA systems with just a single subwoofer and two full-range speakers. This eliminates the need for external processing or crossover, thanks to a balanced X-Over signal to the left and right speakers.

User-friendly controls on the amp panel offer the flexibility to operate with Mono or Stereo audio feed, activate polarity inversion, and choose Outputs link mode (True Bypass or X-Over). For those moments when an extra punch is needed, a low-frequencies boost EQ can be activated via the Sub Mode switch.

The SUB 618 is not only efficient and versatile but also durable. It features a full grille design housed in a lightweight wood cabinet, reinforced with a scratch-resistant black covering. Carved side handles enhance portability, while the design of the top side facilitates sub stacking in larger systems and includes a M20 pole mount thread to stack full-range speakers.

Whether you're setting up for a medium to large venue or a home theater, the SUB 618 Active Bass-Reflex Subwoofer with its 18" woofer and 600W RMS power offers a high-quality, powerful, and durable solution for your audio needs.
