#54 HSU Research CCB-8: $699 HSU Research
Pros: Legitimately good midrange and mid-bass punch below about 1kHz, with in-room bass extension to about 60-70Hz that’s impressive for an 8” coaxial driver running this high a sensitivity (~90dB measured). Wide horizontal dispersion (~55 degrees) that holds up reasonably well off-axis.
Cons: Badly unbalanced top end that the reviewer called ‘just a terrible speaker’ outright - a roughly 7dB peak-dip swing in the upper mid/treble causes real listening fatigue regardless of listening angle (tried on-axis, 15 degrees off, and 30 degrees off, all bad). Resonances around 600Hz and 1.2kHz plus erratic high-frequency behavior hurt imaging noticeably. Would need 9 bands of EQ to get close to flat, and even then two dips near 2kHz and 8kHz are baked into the crossover and can’t be fixed with EQ at all - the reviewer’s verdict was simply to skip it.
How it compares: Just above it: Fosi Audio SP601 - $299 cheaper. Just below it: Yamaha NS-10 - $200 cheaper.
