How to choose
Match subwoofer output to your top speakers and room size, and consider a DSP model if you want built-in crossover control.
Beginner
A small PA gaining its first sub can add the Behringer PK15S or Alto Professional TS315S for a manageable boost in low end. Set the crossover point to suit your top speakers, and avoid running the sub at full volume alone.
Intermediate
Bands wanting a fuller low end for larger rooms often choose the Electro-Voice EKX-18SP or JBL EON718S. Position the sub on the floor rather than raised for the tightest bass response, and check phase alignment with your top speakers.
Expert
Larger systems needing serious low-frequency output use the JBL SRX928S dual subwoofer or the Turbosound iQ18B with its onboard DSP for precise tuning. Set delay and crossover carefully to align subs with the rest of the system, and check load limits when running multiple subs together in a stack.

About Active Subwoofers
An active subwoofer adds low-end weight to a PA system that top speakers alone cannot reproduce, and having its own amplifier keeps the low frequencies properly driven. Bands and DJs buy them to fill out the bottom end for music with real bass content.
This page includes single 18-inch subs like the Electro-Voice EKX-18SP and JBL EON718S, higher-output options such as the JBL SRX928S dual 18-inch sub, and DSP-equipped models including the Turbosound iQ18B.
