a driver - continued
13. Now calculate and record Q
ES
using this formula
Using the measurements from our test woofer we get:
So, Q
ES
= 0.31
14. Now calculate and record Q
TS
with this formula
Using the measurements from our test woofer we get:
So, Q
TS
= 0.28
We are almost done, now we are going to find V
