Speakers are two years old with very little run time. Very forgiving speaker to room ratio. One of the all time best sounding speakers...at any price.
Three-way, five-driver, floorstanding loudspeaker with vented enclosure. Drive-units: 1" (25mm) aluminum-dome tweeter and 5" (127mm) Li-Mg-Al (LCP) hybrid-cone midrange driver in coaxial Uni-Q array, four 6.5" (165mm) aluminum-cone woofers. Crossover frequencies: 320Hz, 2.4kHz. Frequency response: 40Hz–35kHz, ±3dB. Frequency range: 34Hz–45kHz, –6dB. Sensitivity: 90dB/2.83V/m. Nominal impedance: 4 ohms. Minimum impedance: 3.2 ohms. Harmonic distortion (second & third harmonics at 90dB, 1m)
The Blade Two carries that evolution to the limit. It preserves all the positive qualities that made KEF's little LS50 Stereophile's "Product of 2013," while adding greater dynamic range and two more octaves of bass extension—though at $25,000/pair, this is for a price more than 16 times greater! The low frequencies are balanced to be neutral in a room larger than mine, though too large a room and the top octaves might start to sound mellow—which could be a concern, considering how sweet they already were in my room. But that imaging magic and its midrange clarity make the Blade Two a winner all the way.
