Yamaha YST-SW40 Subwoofer Specification

The Yamaha YST-SW40 is a compact subwoofer designed to enhance the bass performance of home audio systems. It incorporates Yamaha's Advanced Active Servo Technology (Advanced YST), which ensures accurate and deep bass reproduction by using negative impedance feedback to better control the speaker cone. The subwoofer features a 25-centimeter (10-inch) multi-range driver that is capable of delivering a powerful low-frequency response, making it suitable for both music and home cinema applications.

The YST-SW40 is powered by a built-in 70-watt amplifier, which provides sufficient power for most home environments. It operates within a frequency response range of 30Hz to 200Hz, allowing it to cover the essential bass spectrum effectively. The subwoofer includes a variable high-cut filter, adjustable between 50Hz and 150Hz, enabling users to seamlessly integrate the subwoofer with various speaker systems by matching the crossover point to the main speakers.

Connectivity options on the YST-SW40 include both line-level and speaker-level inputs, offering flexibility in setup configurations. The subwoofer is housed in a bass-reflex cabinet design that enhances low-frequency output while minimizing distortion. Its compact dimensions make it easy to place in a variety of living spaces without occupying too much room.

The Yamaha YST-SW40 subwoofer also features a magnetic shielding system, allowing it to be placed near other electronic devices without causing interference. Its robust build quality and advanced features make it a reliable choice for those seeking to augment their audio system with rich, dynamic bass.
