Proel S18A 18″ Active PA Subwoofer

The Proel S18A is an active subwoofer with an 18-inch woofer. Proel’s S Series subwoofers consist of woofers in a Hybrid Band Pass configuration, which increases efficiency, reduces distortion, and improves sound quality all at once. This subwoofer’s Class D amplification delivers up to 1200 W of power with a switch-mode power supply that lets you use it anywhere in the world.
The S18A is built with a plywood enclosure with a strong polyurethane paint, ensuring that it’s strong and lightweight at once. Stereo preamplification and a phase switch makes this subwoofer easily adaptable, with an option to fire the subwoofer forwards and prevent feedback from low-end bleed on stage. It also features a 24 dB per octave crossover with an adjustable frequency, letting you achieve a balanced sound with your main speakers. This larger model also features four wheels for improved portability.
