Since I wanted to upgrade my existing 7.1 system to 7.2, I was looking for a second subwoofer. Businesses are the speakers at a Yamaha RX-V777 AV Receiver. Since I already have the Yamaha YST subwoofer 015 and am very happy with him, should if possible also be Yamaha 2nd. In addition, the new Yamaha YST FSW 050 Subwoofer is exactly the same as 16cm bass driver included with my old subwoofer. Due to its compact dimensions, the subwoofer is ideal for stowing in a shelf. With the sound quality I am very satisfied. Properly low tones, which are predominantly Noticeably, be just as well represented as kick bass. Depending on taste, the volume at the front of the subwoofer can be adjusted. The overall build quality is very high and solid. All in all I am very satisfied with the new subwoofer and can recommend it without hesitation.
