#120 System One S-15B: $130 per pair Discontinued eBay
Pros: A small budget two-way bookshelf speaker. Measurements show a preference score of 2.45 that reaches 5.83 with an ideal subwoofer, with 0.55 listening window deviation. Measured bass extension of 127.0Hz (-3dB).
Cons: The on-axis response is uneven (1.19 average deviation) and bass is limited. That data is low quality, and no current retail listing could be found. Bass reaches 127.0Hz (-3dB) and about 65Hz (-10dB). That data is low quality. Discontinued.
How it compares: Just above it: Technics SB-F1 - $15 cheaper. Just below it: TEAC S-300HR - $670 more.
