The extremely stiff cone made from aluminium/magnesium alloy gives tremendous
bass precision. It acts as a piston through the audible frequency band without
showing any sign of midrange resonances.
A unique radial reinforced rubber surround reduces radial resonances and prevents
surround break up at large excursions.
Heavy copper rings mounted above and below the T-shaped pole piece reduce non
linear and modulation distortion and increase overload margin.
A copper phase plug reduces compression due to temperature variations in the voice
coil, increases long term power handling capacity and eliminates resonances in the
cavity inside the voice coil former.
The extremely stiff and stable injection moulded metal basket keeps the critical
components in perfect alignment. Large windows in the basket both above and
below the spider reduce sound reflection, air flow noise and cavity resonance to a
minimum.

The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a
10L closed box. Input 2.83 VRMS, microphone distance 0.5m, normalized to SPL 1m. The dotted line is a calculated
response in infinite baffle based on the parameters given for this specific driver. The impedance is measured in free
air without baffle using a 2V sine signal.
