4th oder sundown sa 12s box help


Recommended Posts

Looking at the pics it looks like a fairly high ratio design.  So what are the specs on the box?  Chamber sizes/tunings?

How much power are you going to run?

What vehicle is this going in?

What kind of usable frequency range are you trying to get?

Yeah I can figure it out, but I won't be able to get to it until later.

Ok, here are the specs I got from the pictures:

Sealed side - 1.6 cu ft (.8 each)

Ported side - 4.4 cu ft

Tuning - 45 Hz

 

The frequency response is pretty peaky, I don't know if you will the bandwidth you want, but it won't be real far from it.  

An 8" aeroport is not big enough, if you want to use an aero port you need to use a 10".
