Program power is defined as the transducer’s ability to handle normal music program material. ** T-S parameters are measured after an exercise period using a preconditioning power test. The measurements are carried out with a velocity-current laser transducer and will reflect the long term parameters (once the loudspeaker has been working for a short period of time). *** The Xmax is calculated as (Lvc - Hag)/2 + (Hag/3,5), where Lvc is the voice coil length and Hag is the air gap height. 15CXA400Nd COAXIAL TRANSDUCER www.beyma.com FREQUENCY RESPONSE AND DISTORTION HIGH FREQUENCY RESPONSE [dB] [dB] LOW FREQUENCY RESPONSE [Hz] [Hz] Note: On axis frequency response measured with loudspeaker standing on infinite baffle in anechoic chamber, 1W @ 1m FREE AIR IMPEDANCE CURVE POLAR PATTERN [Ω] 500 Hz 1 kHz 2 kHz 4 kHz 8 kHz 16 kHz [Hz] [dB] FILTERED FREQUENCY RESPONSE [Hz] Polígono Industrial Moncada II ▪ C/.
