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 //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

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

well I am leaning more towrds spl since I prefer R&B/Hip-Hop...do you think I should go lower?

tune to 30 or so

 

[Jmac2043 10+ year member]

really? shoot...I was way off...will 30hz still provide some spl?

sit a SX im sure it will suply plenty of SPL while maintaining ssome SQ

i will be putting 900wrms to it so I am hoping that the spl will be there...ok I guess i will tune to 30-32hz

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

Eh, just download WinISD Pro from http://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.
