Impedance: 8 ohms nominal, 7 ohms minimum.
System impedance indicates whether the speaker presents a "hard" or "easy" load on the amplifier. True 8 ohm speakers are less amplifier and cable sensitive, and partner well with a broader range of amplifiers, including tube designs.
Crossovers: Asymmetrical Infinite Slope Crossover at 2.5 kHz.
Constructed of specially selected components, Each individual network is precisely adjusted, resulting in a virtually perfect match to the original prototype.
The steep filter slopes ensure good acoustical behavior in the crossover regions, with a minimum of acoustical interference, along with low distortion and wide dynamic range. Driver acoustic responses are in-phase throughout the crossover regions.
The Prism delivers a very smooth and even response over a very broad listening window. Unlike conventional low order crossover designs, the speaker retains its sonic balance over a wide angle both vertically and horizontally. This results in a higher level of fidelity than a simple on axis measurement can reveal.
Listening window response: 2dB from 47 Hz to 20 kHz.
Dimensions and weight: 14" (356 mm) H x 7" (178 mm) W x 12" (305 mm) D.
Shipping weight: approx 22 lbs. (10 kg) each.
