Meyer Sound USW1P AMPLIFIED SUBWOOFER

Meyer Sound USW1P AMPLIFIED SUBWOOFER

Combining advanced loudspeaker technology with equally advanced power capabilities, the Meyer Sound USW-1P self-powered subwoofer provides flat, low-frequency response from 35 Hz to 180 Hz. The USW-1P performs seamlessly within a full range system, in conjunction with UPA-1P, UPA-2P and UPJ-1P loudspeakers. The USW-1P is also fully compatible with other Meyer Sound self-powered loudspeakers.

Features:

• Classic design configuration with proven heritage from USW-1 model
• High peak power capability for excellent transient reproduction
• Built-in crossover allows for simple daisy chain signal distribution and eliminates the need for external crossovers
• Compact cabinet satisfies a broad range of installation requirements
• Flat phase response for optimal crossover to mid/high systems
