So I'm bored again, and decided that for the hell of it, I'd try my hand at building a 4th order for one of my pioneer ts-w5000spl 12's. TBH, I've never designed or built a 4th order enclosure before so this might be a trial and error deal.
So far, all I can come up with based on the space I have is 1.5 sealed/2.5 ported. Max dim's in the trunk are 30 wide x 15 tall x 20 deep, so not a lot of room. Or I can build it to go where my backseats used to be, which gives me more room, 40 wide x about 18 tall x about 20 deep. If I do this, I can do the 1.5 sealed, and like 4.5 ported, so 3 to 1 instead of like a 1 to 1.5 in the trunk.
What I'm curious about is how to go about tuning the ported side to around 50 hz and what size port I should make and where to put it at. I've never heard of anyone putting these subs in a 4th order before so I'm hoping someone with some experience both with this sub or with 4th orders can chime in with some tips.
