Of course, you can also set an upper cut to the subwoofer output to perfectly fit with the scope of the rest of the speakers used. Consumption of this subwoofer on standby at a mere 0.3 watts. In addition, it is magnetically shielded to minimize interference with home electronics.

New twisted widespread reflex port

Brand new Twisted widespread reflex port uses extensive experience in the development of subwoofers Yamaha. Widespread, gently twisting shape diffuses the airflow generated around the edge of the port and creates a smooth flow of air. This reduces residual noise, which does not come from the original signal and ensures clean, accurate reproduction of low frequencies. From special effects in films to the atmosphere of live concerts, always you hear readable bass that is solid and realistic.

PWM digital amplifier with a dual feedback

Built-in amplifier delivers a stable output powers of 250 W, all in addition to the high efficiency with minimal energy consumption and the production of residual heat. This system does not require an output filter coil, resulting in extremely low noise and distortion. Double feedback reduces distortion twice and results in higher purity of sound.

Advanced YST II for an amazing depth of bass

Yamaha Active Servo Technology II combines the principles of negative impedance and constant current control to the speaker with an even more precise control than it was for the first version. Using advanced circuit converting a negative impedance is dynamically optimized effective speaker impedance to ensure excellent linearity. Thanks to this, you can look forward to more stable and accurate response at low frequencies and higher overall sound quality.
