RW165/1
L0017
High End automotive woofer.
Precision cast and surface treated magnesium cone coupled to a natural rubber surround
showing no sign of midrange (edge) resonances.
Large magnet system with bumped back plate makes room for extreme coil excursions.
Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear
and modulation distortion and increase overload margin.
Extremely stiff and stable injection moulded metal basket keeps the critical components
in perfect alignment.
Gold plated terminals mounted on a glass fibre reinforced plate reduce contact resistance
and improve reliability.

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.
