that was on an audiopipe 3500 wired@1ohm, never measured rise.

What the hell is the problem in here? You can't do 47 with 5k and a pair of XL's in a hatch?

Wow.

Wow.

What's your input master?

Wow.

This is what I was thinking. I think @princ3mo ; has the same car and he should be able to help. I have seen a some pretty high numbers (over 150) in these types of cars on less than 3000 watts. I know one guy (can't remember his name) has been helping out with USACI competitions in the south, and he was running just one twelve in a hatch and was doing 150's.

Please don't get upset at what I am about to say, please please please. I would pass my designing off to a trained pro. There are variables you may not have thought of that can not only save space, but keep your tuning low, or increase your effective response curve and be a better number getter, and also a Daily ground pounder.

No matter what, I am in to learn something!! I hope you keep posting updates so we can all learn from your experiments!

This is not a typical square back hatch. It's more like a trunk with the seat out.

make flat surfaces. it is not that hard. and seriously, with 5k a 147 should have come to you a while ago.

I would have 50s already if I tuned higher. I'm trying not to.

still easy to do with low tuning

then figure out what you really want. either go with a removeable port so you can have a daily/spl system or choose between the two.

No ****. If I could do changeable ports I would have a long time ago. With this equipment I should have to sacrifice much SQ to put up decent numbers. I'm not going for a world title here.

How low is low to you?

For where its tuned the output is good. Im just trying to find that line, numbers/daily. I dont want to put up a good number and not move a lick of air. I dont want to play 25hz strong and only meter a 45. It would be great is I could do changable ports but I cant. My car peaks to high to put up a good number tuning low, I learnt that lesson. There has to be a more efficent way to get the best of both.

A larger box. Just because DC softparts break prematurely doesn't mean they won't play lower louder in a large box.

There's no magic DC pixie dust that makes a large woofer not want a large box to perform properly, really for the most part there's nothing special about them over a dozen other comparable chinese built woofers.... if I'm wrong and there's reallly some unique technology used in them, I'm curious to learn about it.

It has all been said here, if you want numbers, tune higher, build a more efficient (bigger) box, or add more power, or add more cone area.

32hz tuning will still yield good numbers

So explain the octo ported box a few pages back putting up impressive numbers. It's a pretty small box.
