Tannoy HPD-315 frequency response measurements Dataset
I used the HobboyBox HBX V.6.5 measuring software with a iSEMcon EMM-8 calibrated microphone on my DELL Studio laptop with good internal soundcard (24 bits, 48000kHz, THD<-70dB). The semi-anechoic measurements were done on a self made DIN 45575 standard baffle (165 x 135, speaker at 65 & 55 cm) on which I placed the speaker in a 100 liter closed and moderate damped closed box and the measurement microphone at 1 meter.
The data set in steps of 150 Hz is:
Frequency Hz |
Amplitude Woofer dB |
Absolute Phase° woofer |
Amplitude Tweeter dB |
