Looking for a 4th order box design

[wmrcs]

I'm going to be putting 2 Sundown SA-8 v.1's into a 4th order. Will be running the pair off of a Hifonics BRZ 1200.1D at 1 ohm so about 600 rms each. I want it to play into the high 20 hz (port tuning like 30hz) range and then as high as I can go from there. Whatever that is, I want it. I care more about the lows than the highs. Let me know if you can give me some tips/recommendations/designs you already have/ways to design my own etc.

i dont know enough about those woofers to give you a gauranteed to work 4th order for them..but you dont tune 4th orders that low.. the magic of a good 4th order is it can peak in the 40's and still reach down and punch ya in the nuts at 30.. but id prolly try around 1 sealed and 2 ported if i was building tuning in the mid to upper 40's and adjust the port till i got the desired effect and a good response

Okay well I know nothing about 4th orders except that they have nice frequency range and are like a sealed and ported box in one. Right? I'm really hoping someone has a 4th order design for 2 already that they've used haha

Hit me up. SA's work well in 4th orders. I could design you something.
