I cant seem to make sense of any of these numbers. I ordered an RE SX 12" and I am trying to come up with a diagram for the box...I want a ported (slot) box tuned to 38Hz...these are the figures I am trying to make sense of....

Common specs for SX:
RE/DCR 1.9 Ohm DVC
Bl 21

SX12
Fs 30.6
Qms 4.4
Qes .32
Qts .30
Mms 183
Vas 47.6
Spl 88.1
Sd 480

I have no friggin clue what to do :(

Why 38Hz? That's a little high isn't it?

if in doubt, follow the specs on their website or ask the builder, David@teampsi

Eh, just download WinISD Pro from www.linearteam.dk and play around with that. It tells you the volume of the enclosure and length of the port when you input your desired tuning point and the diameter (or length/width) of the port.
