Short answer: the KEF Blade Two Meta for better sound quality, the Klipsch Heresy IV for the lower price. The KEF Blade Two Meta ranks #2 of 71 floorstanding speakers at $28000. The Klipsch Heresy IV ranks #44 at $3198, $24802 cheaper.
What the Klipsch Heresy IV offers: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement—well below Klipsch’s 99dB in-room claim, but still excellent—and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. The compact, furniture-grade Heritage cabinet is easier to place than most high-efficiency designs, and dynamics at moderate levels can sound lively. A stable four-ohm-capable amplifier can produce substantial SPL with relatively little voltage. Watch for: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction. The impedance dips to about 4 ohms, reducing the practical amplifier advantage implied by its sensitivity. Pronounced directivity mismatch at the driver transitions, impedance/response resonances and elevated distortion spikes around the crossover remain audible concerns that EQ cannot fully solve. At 102dB Erin measured roughly 1.5dB midband compression; at 96dB distortion rises around crossover. Performance is difficult to justify at the price, and Erin explicitly did not recommend it.
What the KEF Blade Two Meta offers: True point-source coaxial design (four 6.5in mid-bass drivers flanking a coincident mid/tweeter) with matched ~50 degree horizontal and vertical dispersion, unusual for a multi-driver speaker. Fully rounded, edgeless cabinet eliminates baffle diffraction. Frequency response holds within about 2.5dB across the listening window. Extremely low harmonic and multitone distortion even at 96dB, with under 0.5dB of compression at full output, rivaling the Reference 1 Meta and JBL 4367 in dynamic range. Reviewer described the imaging and soundstage depth as revealing recording details other speakers he tested (PS Audio FR10, MoFi SourcePoint 8, Neumann KH80) masked. Available in any custom finish at no extra charge. Watch for: 2dB dip and slight resonance around 200Hz, also visible in KEF white paper and likely cabinet-related. Bass rolls off fairly quickly below its 31Hz F3. Horizontal dispersion (~50 degrees) is narrower than the reviewer preferred 70-80 degrees; benefits from toeing out 10-20 degrees to open soundstage without losing image focus. Needs a separate power amp, not AVR-friendly.
