#23 Focal Solo6 ST6: $1,499.00 B&H Photo Sweetwater

Pros: Beryllium inverted-dome tweeter over a 6.5” ‘W’ composite sandwich-cone woofer - a low-mass, low-distortion driver combination rarely found below far pricier monitors. Directivity control is the tightest of this entire batch (directivity_spdi_stddev 2.87), and the listening-window response is smooth (smoothness_listening_window 0.380). Bi-amped 130W total (80W Class G woofer + 50W Class AB tweeter), each driver on its own amplifier. ‘Focus Mode’ switches the cabinet to a single-driver full-range reference signature for a second mix-translation check without extra hardware. Bass reaches 46.9Hz at -3dB / 38.1Hz at -10dB, solid for a 6.5” driver.

Cons: Bass alignment Q (lfq 0.826) is on the higher side, which can correlate with a touch of extra bass fullness/looseness versus a more critically-damped alignment. XLR-only balanced input, no unbalanced/TRS or digital connectivity. No automatic DSP room correction - tuning is limited to fixed analog shelving/high-pass switches. At $1,499 each ($2,998/pair), it’s a meaningful step up from typical prosumer active monitors.

How it compares: Just above it: PSI Audio A21-M - $2221 more. Just below it: Presonus Eris Studio 8 - $1037 cheaper.
