Cool "CRX" design . whats this sub forward port back crap?!?

i have a 1983 porsche 944 im throwing 4 10's in and came across a design with 4 8" sa's firing forward , and a huge port in the back of the box firing backward. is this actually a good design to go with ? seems a little fishy too , especially the post said it was just a scrap wood " throw together " box pulling 153's outta 4 8's !!! so how would one go about figuring the dimensions for this type of build and all ?

1. yes the box can work with a lot of testing and tuning, but its an SPL box
2. that was in a crx, you can fart a 150 in those

everything else aside, mainly because I have no idea..

The guys at Sundown "throwing" something together should be expected to outperform 90% of the people on here trying to do something right. Not a slam to them or anyone else, but knowing exactly how the sub preforms is handy.

That link is actually Jacob (the owner of Sundown), but I had a VERY similar box in my CRX with (4) SA'8 that did 153.8 officially at a show in stock 0-600w class.

To say that CRX style boxes work in a CRX is an understatement. Lol. I bet the first guy who tried subs forward port back shit himself.

If your car has a similary shaped cabin, I'd say it's definitely worth tesing for SPL, but I can't tell you whether that orientation would be good for daily listening.

More fun in the CRX...
Got a 5 gallon bucket?

Another win for Sundown.



154.2



154.6
