Klipsch RP-1400SW

Through the optimal balance of amplifier power, driver performance, and cabinet volume, the Reference Premiere Subwoofer achieves maximum low-frequency extension with high output, precision, and speed. The built-in, highly efficient Class-D amplifier features an analog preamp design that maintains the original signal path for clean, source-accurate reproduction. The Class-D output stage ensures maximum efficiency even at low frequencies. The proprietary internal geometry with an Aerofoil slot port design minimizes port noise for clean, undistorted deep frequencies. The front-firing design allows for flexible placement, such as directly against a wall or in a corner. Phase control is adjusted with two knobs for the personally ideal bass level. With only ½ watt in standby mode, this subwoofer meets global efficiency standards.
