H1456-08 ER18RNX
ER18RNX is an 18 cm (6,5’’) cone driver, developed for use as a long throw high
fidelity woofer or woofer/midrange unit.
Edge coated reed/paper pulp cone together with perfectly matched moving parts
gives a smooth, extended frequency response.
Bumped back plate in the magnet system, together with the very long and light
weight copper clad aluminium voice coil, allow extreme coil excursion with low
distortion.
Heavy copper ring below the T-shaped pole piece will reduce non linear and modulation
distortion.
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.
Frequency response
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.
