#140 Yamaha NS-A638 Discontinued eBay
Pros: A budget two-way bookshelf from Yamaha. Yamaha’s measurements show a preference score of 1.77 that reaches 5.06 with an ideal subwoofer, with 0.68 listening window deviation.
Cons: Bass is limited and the on-axis response is uneven (1.15 average deviation). The data comes from Yamaha and its quality is unknown. Yamaha no longer sells it. Bass reaches 195.8Hz (-3dB) and about 56Hz (-10dB). That data is of unknown quality. Discontinued.
How it compares: Just above it: Verdant Audio Bambusa AL-1. Just below it: JBL Stage A130.
