• PSW enclosures are designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances.
• This unique configuration uses a specially tuned and directed port to more efficiently produce maximum bass impact.
• Combining just the right driver materials, speaker geometry and enclosure construction techniques has a synergistic effect that produces cleaner, clearer sound.

• Easily accessible, professional-grade line- and speaker-level inputs and speaker level outputs, allow easy connection to any system.

Intelligent amplifier also features adjustable low-pass crossover, phase switch & subwoofer volume controls to professionally control your bass output and the subwoofer's blending characteristics with your front stage speakers.
