#35 JBL M2 Master Reference Monitor: $15,000 per pair JBL Professional Dealer Locator eBay
Pros: A high-output specialist: Erin’s low-distortion and compression tests support considerable dynamic capability, beyond what a single preference score captures. Measured -3dB extension is 33.7Hz. The large woofer and waveguide are particularly useful for greater listening distances. Measured bass extension of 34Hz (-3dB).
Cons: Its 4.1dB response span from 300Hz to 5kHz and 6.58 ideal-subwoofer score do not support a top tonal-accuracy ranking. It requires the correct external amplification and DSP rather than a simple built-in amplifier. The very large cabinet, installation cost and possible amplifier fan noise make it impractical for most desks.
How it compares: Just above it: APS Klasik 2020 - $14100 cheaper. Just below it: Palmer Orbit 11 - $14234 cheaper.
