Usher CP-6381 Beryllium

Beschrijving / Description

The Usher CP-6381 is much larger than its photos suggest. It stands 50 inches tall, 16 inches deep and 13 inches wide. Ostensibly to time-align the drivers, the speaker cants rearward, making the speaker's effective depth closer to 22 inches. Additionally, the CP- 6381 comes equipped with bolt-on iron bases that are about 25 inches deep and 14 inches wide. Each speaker weighs 143 lbs including the 30-lbs base. Given the 8-inch woofer, I anticipated a speaker two-thirds the actual size of the CP-6381 which was much closer to my old Silverline Sonata IIs sporting dual 10-inch woofers. As if this kind of mass weren't enough, the CP-6381 features a compartment at the speaker's bottom (accessed via a little trap door at the rear) that's designed to be filled with sand.

The CP-6381 really is exceptionally well finished. The review pair came in a silver-metallic utomotive-type finish though glossy white and black are available as well. To my roaming eyes, the finish was absolutely flawless and commensurate with products thrice the CP-6381's price - no kidding. The wooden cheeks were sanded smooth and covered by a light satin finish that complemented the high-gloss lacquer nicely though I would have preferred that the wood extend down to the speaker's base. Interestingly and like some metallic finishes, the hue of the CP-6381 varied with lighting conditions though it usually had a golden tint that fluctuated in intensity yet was always highly attractive. The CP-6381 is a 3-way system using a 1-inch silk dome tweeter, a 7-inch mid-bass driver and an 8-inch woofer. Both woofers are of the doped paper variety. Around back are two pairs of WBT-cloned shrouded binding posts for biwiring (unlike real WBTs, you can unscrew these until the nut comes off in your hand). Usher claims 87dB sensitivity, a nominal impedance of 8 ohms and a frequency response of 29- 28kHz (-3dB). Other than crossover frequencies of 323Hz and 2.6kHz, they don't spell out any further information on the network but they do specify a power handling of 160 watts.
