Yamaha's Advanced Active Servo Technology is a complementary amplifier/speaker system utilizing negative impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass.
8-inch Driver and 100 Watt Amplifier
High amplifier power assures enough power to deliver movie theater-like bass effects, and the 8-inch cone driver translates the power into clear bass sound. The YST-SW012 has a frequency range of 28 to 200 Hz.
The speaker is magnetically shielded, so it can be placed on a TV or video monitor without degrading the picture via stray magnetic fields.
The volume control permits the perfect matching of the sub's output to the overall volume of the system.
The Linear Port provides smooth bass response during playback and minimizing extraneous noise.
