Subwoofer Omnitronic BX-2250 30 cm 800 W

The Omnitronic BX-2250 Subwoofer is a passive PA subwoofer with a 30 cm (12") driver and an RMS power rating of 800 W (max. 1600 W). It reproduces low frequencies from 20 to 400 Hz using a bass-reflex cabinet designed for dry, powerful bass. The enclosure features a durable black felt covering, steel protective corners and a sturdy front grille. The speaker is provided with pole-mount handles for transport and placement and uses an 8 ohm impedance with SPK output for connection.

Advantages

This passive subwoofer provides strong low-end support for top cabinets and DJ systems, delivering pronounced, punchy bass through a voluminous bass-reflex enclosure. It offers high power handling, a switchable passive crossover, and rugged mechanical protection for mobile use or permanent installation.

How to use

Connect the Omnitronic BX-2250 to a compatible power amplifier and top cabinets using the SPK socket and appropriate speaker cables, respecting polarity and the 8 Ω impedance. If required, enable the passive crossover to route low frequencies to the subwoofer and highs to the satellites. Position the cabinet on a stable surface or mount a satellite on a pole above the subwoofer using the built-in pole receptacle. Adjust amplifier gain and crossover settings on the amplifier or processor to blend the subwoofer with the main speakers while avoiding overload.

Recommendations

For reliable long-term operation, use an amplifier with adequate headroom relative to the 800 W RMS rating, protect connections during transport, and avoid exposing the felt covering to prolonged moisture. Place the subwoofer to minimize cancellations and achieve even bass distribution in the listening area.
