Cerwin-Vega P1800SX overview

  • 1Description

The Cerwin-Vega P1800SX 18" Active Subwoofer compliments the P-Series portable speaker system with low frequency extension. This powered subwoofer employs an 18" woofer with a custom 2,000W Class-D amplifier. The woofer and the matched amplifier are enclosed in a multi-ply hardwood cabinet, which helps enhance the low-frequency response.

The frequency shaping controls and VEGA BASS boost ensure that the user can dial in the correct extent of bass for each venue. While designed for use with the P1500X Bass-Reflex Speaker, the P1800SX Subwoofer can also be used for low frequency extension with other Cerwin-Vega tops or even other brands.



Rugged enclosure with multiple handle locations makes transport and setup safe and easy.
Uses high-efficiency Cerwin-Vega components for low-frequency bass.
The integrated mixer and amplifier design makes the subwoofer suitable for use in limited power source environments and reduces the number of gear required for an easy setup.
Stackable design to minimize transportation and storage area. Thick, powdered coated grill protects the drivers during transportation and storage.
Casters are included with the P1800SX Subwoofer for easy transfer to and from the performance area.


The 2,000W Class-D amplifier delivers low frequency extension.
Built-in limiter with On/Off LED indicator provides essential protection to minimize the risk of down-time and prevent component damage.
