Yamaha YST-SW205 Powered Subwoofer

The Yamaha YST-SW205 is a compact, vertically designed, powered subwoofer sporting 8-inch front-firing driver, coupled with a 150-watt amplifier. The SW205 features "Active Servo Technology" for optimum linear speaker motion, providing less distortion between higher and lower bass frequencies. Frequency response is listed at going down to 23Hz and upper bass frequencies to 170HZ. The subwoofer has an adjustable crossover from 40-140HZ, which can be accessed via the front control panel. The front of the subwoofer consists of the low-frequency driver and upper bass frequency port as well as controls for Standby Power, Movie/Music Mode, High Cut (crossover frequency adjustment), and Volume. The rear panel of the 205 consists of the main power switch, line-level (RCA-type connections) input for amplifiers with a line-level subwoofer output. In addition, traditional speaker connections are provided for amplifiers or home theater receivers with no line-level subwoofer output. These connections pass through to main or satellite speakers for mid and high frequencies, auto standby setup switches for automatic operation, and phase switch to compensate for speaker polarization issues. The Yamaha YST-SW205 can be a great addition to a modest to mid-range home theater system.
