The PP/TPX based cone matches ideally with the adaptive rubber surround. This
results in an outstandingly smooth frequency response from the mid woofer.
The coaxially arranged precoated fabric dome high frequency unit has a low resonance frequency, and integrates with the cone driver to a point source.
The cone of the woofer acts as a horn loading for the tweeter, and the chassis of the
dome unit represents the throat of this horn.
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 12L 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.
