#16 GGNTKT M1: £7,500 per pair Purite Audio (UK) eBay
Pros: The manufacturer-supplied monopole measurement shows a 1.6dB response span from 300Hz to 5kHz, 33.8Hz -3dB extension and a 7.03 ideal-subwoofer score. Those results support even midrange balance and useful bass from a relatively shallow cabinet. Measured bass extension of 33.8Hz (-3dB).
Cons: The cited measurement is specifically monopole, so it cannot substantiate claims about cardioid-mode performance. Outboard electronics add cabling and installation complexity; confirm the complete system configuration before purchase. On-axis narrow-band deviation of 0.475dB is rougher than its listening-window smoothness, so a listener dead center may hear more unevenness than the off-axis figures suggest.
How it compares: Just above it: Buchardt A500 - 557W less output power. Just below it: Neumann KH 310 A - 270W less output power.
