#2 Kii THREE: $14,000/pair Vintage King
Pros: A genuinely full-range active cardioid monitor. Erin measured a 28Hz F3, and boundary gain in his room kept useful response close to 20Hz. Four side/rear 6.5-inch woofers use DSP delay and cancellation to suppress rearward radiation above roughly 70-90Hz, reducing front-wall and sidewall interaction while the 5-inch midrange and waveguided tweeter maintain exceptionally smooth directivity. Six Ncore amplifier channels provide 1,500W total per cabinet, phase-exact mode offers precise impulse behavior, and Erin found imaging, tonal neutrality and left/right symmetry outstanding.
Cons: The protection limiter becomes evident above approximately 96dB at 1m; bass-heavy material can overdrive the compact woofers with an audible plop even though many tracks exceed 100dB at a four-meter seat. The BXT modules are the appropriate but very expensive solution for more deep-bass headroom. Erin preferred the treble control at -2dB because broad radiation around 3-5kHz could sound sharp. Phase-exact operation adds latency, while low-latency mode trades away some low-frequency correction. System cost, proprietary connectivity and 42-pound cabinets also narrow its audience.
How it compares: Just above it: JBL M2 Master Reference Monitor. Just below it: Dutch & Dutch 8C - $1000 cheaper.
