Παθητικό subwoofer Omnitronic BOB-82X 8 ίντσες 300 W

The Omnitronic BOB-82X is a passive subwoofer with an 8" driver and 300 W nominal power, designed to extend the low-frequency response of PA, DJ and studio speaker systems. As a passive unit, it requires an external amplifier and is intended to complement full-range loudspeakers by providing deeper bass reproduction and better low-end impact in small venues, rehearsals, home studios and mobile setups.

Advantages

The compact enclosure and 8" driver deliver concentrated low frequencies while keeping the footprint small, making placement flexible in limited spaces. The 300 W nominal rating enables reliable low-frequency support for small to medium setups when paired with an appropriate external amplifier. The passive design allows users to choose amplification and DSP suited to their system, offering adaptability and integration with a wide range of full-range speakers.

Key specifications

How to use

Connect the subwoofer to an external amplifier with appropriate power and impedance matching, then integrate it with full-range speakers using a crossover or DSP to set the cut-off frequency and level balance. Position the cabinet on the floor near the main speakers or where bass reinforcement is needed, and adjust phase and level controls (on the amplifier or processor) to achieve a coherent low-frequency response with the main system. Ensure secure speaker cabling and safe placement to avoid vibrations or movement during operation.

Recommendations

Use an amplifier that matches the nominal power handling and impedance of the subwoofer, and apply a low-pass filter or DSP crossover around the chosen frequency to avoid overlap with full-range speakers. For tight bass in small rooms, experiment with placement close to walls or corners, and use phase adjustment to align transient response with the main speakers. Regularly check connections and mounting to maintain safe and reliable operation.
