New Curv cone, a woven polypropylene with excellent internal damping together
with perfectly matched moving parts gives a smooth, extended frequency response.
A unique radial reinforced low loss rubber surround reduces radial resonances and
prevents surround break up at large excursions.
Bullet shaped phase plug reduces compression due to temperature variations in the
voice coil, avoids resonance problems which would occur in the volume between the
dust cap and the pole piece and increases the long term power handling
capacity.
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.
This driver use Seas SpiderRing® technology.

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.
