I have the recently purchased the passive 12" tube. I kind of need to know the port length and diameter and volume for T/S parameters.
I am replacing the driver and adapting the enclosure for use as highly portable and efficient bass guitar cab. I love this driver and this obviously is not what the enclosure is designed for.
But any help would be appreciated. Hopefully, SAS will expand into pro sound with a line of portable speakers.
I am wondering if the port length needs to be trimmed to bring up the tuning frequency to 48hz.
The T/S paramaters are
Resonant Frequency (fs)
DC Resistance (Re)
Coil Inductance (Le)
Mechanical Q (Qms)
Electromagnetic Q (Qes)
Total Q (Qts)
Compliance Equivalent Volume (Vas)
91 liters / 3.2 cu. ft.
Peak Diaphragm Displacement Volume (Vd)
Mechanical Compliance of Suspension (Cms)
BL Product (BL)
Diaphragm Mass inc. Airload (Mms)
Efficiency Bandwidth Product (EBP)
Maximum Linear Excursion (Xmax)9.8mm
Surface Area of Cone (Sd)
Maximum Mechanical Limit (Xlim)
