About the CP6381

The Usher CP-6381 is a three-way, ported floor-standing speaker system with a 1.25-inch silk dome tweeter (often upgraded to Usher DMD or beryllium tweeters), a 7-inch midrange driver, and an 8-inch woofer, both of which use doped paper cones. It offers a frequency response from 29 Hz to 28 kHz (-3 dB), a nominal impedance of 8 ohms, and a sensitivity of 87 dB/W/m. The crossover frequencies are approximately 290 Hz and 2.57-2.6 kHz. The speaker weighs about 139 pounds each and measures 51 inches high, 13.8 inches wide, and 25.6 inches deep. It is known for a wide and deep soundstage, quick and articulate bass, smooth and transparent midrange and highs, and a natural timbre with low distortion. The design includes separate internal enclosures for the midrange and woofer, each rear-ported, and bi-wiring capable binding posts. Some users enhance performance by filling the mass load chamber with sand and upgrading the tweeter to a beryllium model for improved midrange focus and bass control. The CP-6381 is praised for its musicality, power handling (150-160 watts), and ability to deliver detailed, balanced sound without fatigue, suitable for both music and home theater applications.
