CA18RLY
H1217
6,5” High Fidelity cone driver, developed for use as a high quality woofer or
woofer/midrange unit.
Classical coated paper cone gives a smooth extended frequency response
with a controlled roll off.
High temperature, light weight, CCAW voice coil wound on an aluminium
voice coil former gives a high power handling capacity. 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 large
magnet system provides high efficiency and low Q.

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.
