Product Details


Your Home Theatre Needs a Subwoofer

A subwoofer is a crucial addition to your home theatre setup. The subwoofer alleviates the need for your main speakers to reproduce bass frequencies, enabling them to reproduce more coherent results in the mid and high frequency bands. It also frees up extra amplifier power to drive these main speakers.

Place Them Anywhere

You should be able to place your subwoofer wherever you like, however your subwoofer’s performance will be greatly affected by its proximity to walls and other reflective surfaces. Yamaha’s down-firing subwoofers employ patented QD-Bass (Quatre-Dispersion Bass) technology to evenly distribute bass energy in all directions, giving you more freedom of placement.

Environmentally Friendly

Having a home theatre should not mean larger power bills. Yamaha subwoofers which feature auto-power are designed to power down when not in use, and automatically come to life when you activate home theatre - just another way we can look after the environment.
