Hi guys, I'm about to embark on an IB sub project. Looking through different drivers 12, 15, 18" , with Qts of around 0.6 one thing remains unclear to me:
If i will cross the sub at 80Hz, how important is the inductance on the sound quality? Can I use the cheaper "closeout" drivers with higher inductance, say 2.5 or 3.1 or will that be a significant compromise? What will change with going to a lower inductance, say 1.2?
The higher the inductance the faster the top end rolls off.
Inductance isn't 'the' single determining T/S parameter, it's just one of several that need consideration when choosing a driver.
I understand. However, given there is a choice of very similar drivers with Fs, Qts, Vas xmax, being similar. But they differ in Le, lets say 0.3 mH and 1.5mH and 2.5mH. I will run them from 30 to 100 Hz, will they sound different or about the same?
