The Cerwin-Vega P1800SX complements the P-Series with low frequency extension. The powered subwoofer employs an 18-inch woofer with a custom 2000-watt Class-D amplifier. The large woofer and matched amplifier are enclosed in a multi-ply hardwood cabinet, the combination, which provides a superior punch and extreme low-frequency response, which are both Cerwin-Vega! trademarks. Like the P1500X, the P1800SX has frequency-shaping controls and the unrivaled VEGA BASS boost. This ensures the user can dial in the correct amount of bass for each venue. While designed for use with the P1500X, the P1800SX can also be used for low frequency extension with other Cerwin-Vega tops or even other brands. Additionally, the THRU, MIX and LINK outputs allow for system expandability and fast daisy-chaining between components.

Cerwin-Vega is one of the most established names in live sound reinforcement, having been part of the working musician's toolkit since the birth of rock and roll. Their culture is deep bass. Their identity is deep bass. Almost every working musician of a certain age has owned and loved some piece of Cerwin-Vega equipment. The company has undergone a revitalization recently, and they look forward to a growing presence in the live sound reinforcement marketplace.

Best sub in the market!!!


from Vista, CA

This sub delivers all the power and punch that I was looking for in a powered sub. I was going to buy the QSC KW181, however, I heard both of them in the show room and I personally think the Cerwin Vega P1800sx delivers better punch. Also, who wants to pay 400$ more for a sub when you can pay less and get better bass? Cerwin Vega is legendary for their bass, so you wont be disappointed for buying this nice sub!! So far I have used it for 11 gigs and people love the bass!!
