Mobile DJs and live sound engineers need low-end reinforcement that can keep up with demanding performances. The OMNITRONIC PAS-181 MK4 delivers exactly that: an 18-inch passive subwoofer built for clubs, touring rigs, and fixed installations where punchy, deep bass is non-negotiable. Its robust plywood enclosure and high-excursion woofer translate amplifier power into chest-thumping output without distortion.

Key specifications

• 18" (45 cm) woofer with 400 W RMS / 800 W program / 1600 W peak power handling
• 8 Ohm impedance for easy amplifier matching
• Frequency response: 35–250 Hz, sensitivity 98 dB (1 W/1 m), max SPL 128 dB
• Bass reflex enclosure made of scratch-resistant lacquered plywood
• Two Speaker Twist (NL4) connectors for secure linking
• M20 threaded pole mount flange for satellite speakers
• Two integrated carrying handles and rubber feet for stable placement

Why choose it

The PAS-181 MK4 is engineered for reliability and sonic impact. Its 18-inch driver moves serious air, while the bass reflex design extends low-frequency response down to 35 Hz. The rugged plywood cabinet withstands the rigors of transport and venue changes, and the scratch-resistant lacquer keeps it looking professional gig after gig. With 1600 W peak power handling, it can absorb transient peaks without breaking a sweat.

Ideal use cases

• Live sound reinforcement for bands and DJs
• Nightclubs and bars needing consistent low-end coverage
• Mobile PA systems for outdoor events and parties
• Fixed installations in houses of worship, theaters, and conference centers

Good to know

The M20 pole mount flange allows you to place a full-range speaker directly above the subwoofer, creating a compact, coherent system. Pair it with an amplifier delivering 400–800 W at 8 Ohms for optimal performance. The NL4 connectors support parallel wiring to additional subwoofers, simplifying cable management in larger setups.
