Haut-parleur medium SEAS L15RLY/P
[L15RLY/P-8] Avis/Critiques L15RLY/P is a 15 cm (5’’) cone driver, developed for use as a long throw high fidelity woofer or woofer/midrange unit.
Stiff, yet light aluminium cone and low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion associated with soft cones.
Bullet shaped phase plug reduces compression due to temperature variations in the voice coil, avoids resonance problems which would occur in the volume between the dust cap and the pole piece and increases the long term power handling capacity.
Extra large magnet provides high efficiency and low Q. This unit may be used in very small two-way ported systems producing an astonishingly deep bass and a clean, neutral midrange.
The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 20L 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.
