SPL vs Frequency measure :
The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 31l closed box. Input 2.83 VRMS, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infi nite baffle based on the parameters given for this specific driver. The impedance is measured in free air without baffle using a 2V sine signal.
