Talking New version of Audio Tester has T/S Measurement.....

Hi all,

Two days back I downloaded the shareware version of audio tester V2.1. It has a new feature which allows direct measurement of T/S parameters (both mass loaded and volume). I think this is one of the easiest and one of the most user friendly (means no going thru tutorials ). Just now I measured the T/S of two drivers SUB166SPP subwoofer from dainty(Chinese) and YP 8"(indian) subwoofer the details are given below

Parameter Value
fs 47.7 Hz
Zmax 92.4 Ohm
Rdc 16.4 Ohm
Qms 3.15
Qel 0.68
Qts 0.56
Mmd 29.90 g
Cms 0.37 mm/N
Vas 7.96 liter
