Hi All,

I am trying to simulate 4th order bandpass for a 10" driver.

I am unclear about three parameters. (please see the attached images)

1. SYSTEM DAMPING FACTOR (DF)

2. SYSTEM TOTAL Q (Q't)

3. VENT LOSSES (QLv)

Are there any ideal values for SYSTEM DAMPING FACTOR and SYSTEM TOTAL Q? Are those variables to keep changing and trying different response graphs?

Any maximum and minimum limits for those? Do they depend on driver TS parameters? Can any one throw some light please....

Secondly, assuming the overall enclosure is perfectly sealed without any leakages, what should be the value of VENT LOSSES? (7 to 15 as far as I know)

Thanks a lot for any help...

Regards

Naveen
