Extra Bass Provides Rich Bass Reproduction, Even with Small Speakers
Yamaha’s exclusive low-range enhancement technology delivers richer bass than you expect from the speaker size while maintaining good localization and sound balance even with compact front speakers. When a subwoofer is used, it improves the volume of the entire low range of the speaker system, not only the front speakers but also enhancing the bass from the subwoofer.

Subwoofer Trim for Improved Sound Imaging
The Subwoofer Trim control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused sound stage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim takes care of this by separating the low subwoofer frequencies cleanly, thus stabilising the front stage while providing a well-balanced enhanced bass sound.
