ScanSpeak 12W/4524G00

HiFiCompass would like to express deep gratitude to Tihomir Haralovic for his help in replenishing our measurement database and for kindly providing the ScanSpeak 12W4524G00 midwoofer for testing. Tihomir Haralovic graduated physics in Zagreb University, Croatia, and is the owner and chief audio engineer in Neutrino Audio company, which develops high-end analog active crossovers and loudspeakers. Tihomir and his team believe that an analog active crossover is a much better choice for an audiophile than digital (DSP).

The HD measurements (315 mm) at voltage levels 2.83 - 8 Volt were carried out with High Pass Filter "on" (2nd order Butterworth type, 80 Hz cutoff, HPF2-80)

The HD measurements (315 mm) at voltage level 11.2 Volt  were carried out with High Pass Filter "on" (2nd order Butterworth type, 120 Hz cutoff, HPF2-120)

The HD measurements (20 mm) at voltage levels 4 - 5.6 Volt were carried out with High Pass Filter "on" (2nd order Butterworth type, 30 Hz cutoff, HPF2-30)

The voice coil current HD measurements were carried out with High Pass Filter "on" (2nd order Butterworth type, 80 Hz cutoff, HPF2-80)

Before taking the measurements the speaker had been very good broken-in
