Haut-parleur SEAS W16NX001
[W16NX001-8] Avis/Critiques Precision cast, machined and surface treated magnesium cone acts as a piston
through the audible frequency band without showing any sign of midrange
resonances. A unique radial reinforced rubber surround reduces radial resonances
and prevents surround break up at large excursions.
Heavy copper rings
mounted above and below the T-shaped pole piece reduce non linear and modulation
distortion and increase overload margin.
A copper phase plug reduces compression due to temperature variations in the
voice coil, increases long term power handling capacity and eliminates
resonances in the cavity inside the voice coil former. 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 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.
