#22 JBL 308P MKII: $298 per pair Amazon B&H Photo Video eBay

Pros: A 1.8dB response span from 300Hz to 5kHz and 7.69 ideal-subwoofer score support unusually good tonal balance for an accessible studio monitor. Measured -3dB extension of 42.5Hz supplies useful musical bass, and the waveguide helps maintain consistent horizontal coverage. Measured bass extension of 42.5Hz (-3dB).

Cons: Amplifier hiss may be noticeable in quiet, close-range use. Bass distortion and output limits matter when playing loudly, despite the 8-inch woofer. Keep the tweeter near ear height; vertical crossover behavior is less forgiving than the best coaxial designs. A resonance around 18kHz and a slight dip around 1.4kHz.

How it compares: Just above it: SHIVAUDYO Point Zero - 488W more output power. Just below it: O.S. Acoustics DBS8 - $5451 more, 388W more output power.
