#137 KLH 911B Discontinued eBay
Pros: A budget two-way bookshelf from the KLH brand. KLH’s measurements show a preference score of 1.32 that reaches 5.12 with an ideal subwoofer, with 0.68 listening window deviation.
Cons: Bass is very limited and the on-axis response is uneven (1.14 average deviation). The data comes from KLH and its quality is unknown. KLH no longer sells it. Bass reaches 128.8Hz (-3dB) and about 92Hz (-10dB). That data is of unknown quality. Discontinued.
How it compares: Just above it: Cambridge Audio Minx Min 12. Just below it: Q Acoustics 5020.
