#12 AsciLab F6B: $980 per pair Ascilab eBay
Pros: Called by the reviewer the best sub-$1000 pair of speakers he’s come across to date. Very good on-axis linearity and directivity for the price, with a large waveguide-loaded 1” aluminum dome tweeter that keeps a two-way design well-behaved through the crossover. Nice midbass punch from a slightly undersized enclosure alignment that gives kick drums extra impact. Solid, unfussy tonal balance overall.
Cons: A mild sibilance-inducing lift around 6-8kHz, most noticeable on female vocals, paired with a shallow dip in the upper midrange - correctable with a simple 3-band EQ the reviewer provided. In-room bass extension is only about 50-60Hz despite a 6” woofer, trading some low-end reach for that extra midbass punch. Compression and graininess creep in at higher volumes (upper 80s to low 90s dB at 10ft), and directivity (~50-60 degrees horizontal) is narrower than the reviewer’s other current favorite, the Audio First Cadentia 3.
How it compares: Just above it: KEF Q Concerto Meta - $420 more, 0.8Hz lower bass extension (-3dB). Just below it: Wharfedale Aura 2 - $1819 more, 2Hz higher bass extension (-3dB).
