Impedance: 8 ohms nominal, 6 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.

Crossover: 2 way Parallel Asymmetrical Infinite Slope Crossover at 2 kHz. 

Constructed of specially selected components, each network is tested and individually calibrated to a high degree of precision, resulting in a virtually perfect match to the original design prototype.

The steep filter slope ensures 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.

Frequency Response:

The Profile 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:  within 2dB from 39 Hz to 20 kHz.

Dimensions: 39" (991 mm) H x 7" (178 mm) W x 12" (305 mm) D.
