Omnitronic PAS-151 MK4 Subwoofer

Solid Low End for Professional PA Systems!

The Omnitronic PAS-151 MK4 is a passive 15" bass-reflex subwoofer that delivers powerful, deep bass for clubs, events, or mobile DJ setups. With 700 W RMS and a high sensitivity of 97 dB, it provides efficient operation — ideal as a reliable bass foundation for your tops or as a compact sub in a PA system.

Power and Sound Quality

The PAS-151 MK4 features a 15" woofer with a 4" voice coil and ferrite magnet, which reproduces low-frequency bass content cleanly and precisely. The frequency response spans 40 Hz to 200 Hz — perfectly suited to convey kick and sub-bass with punch. With a maximum sound pressure level of up to 128 dB, the subwoofer provides ample headroom for club or live use.

Efficient and Flexible in Operation

Thanks to the high sensitivity of 97 dB (1 W/1 m), the PAS-151 MK4 works efficiently with suitable amplifiers — you get loud, clean bass without excessive amplifier power. With an 8 Ohm impedance, it integrates flexibly into common PA setups. Its passive design gives you freedom in amp choice and lets you tailor modularity and system configuration yourself.

Robust & Transport-Friendly Construction

The multi-ply glued plywood enclosure with a black textured finish and a black metal grille lined with acoustic foam makes the PAS-151 MK4 tough enough for everyday use — whether in clubs, events, or mobile shows. Two recessed handles ease handling during rigging and teardown; optional casters can be retrofitted to simplify transport and storage. Thanks to the bass-reflex design, the subwoofer stays relatively compact and space-saving.

Whether used as the sub-bass foundation of a PA system, as a complement to tops, or as a powerful foundation for DJ or live sets, the PAS-151 MK4 impresses with its combination of powerful bass, efficient operation, and rugged construction. It's a solid choice for anyone seeking reliable low-frequency reproduction and professional performance.
