Seem like a good idea?

the pandpadd desing is wats called a 6th order parallel tuned boxpersonaly i would do a 6th order series tuned box

like this

this imo will work better for spl comps...

That design confuses me. The front and rear waves are not seperated from each other, as is usually critical.

I almost posted the same thing, word for word. If the front and the back wave meet within the enclosure, doesn't that nullify the purpose of a 6th order?

IMO, the best thing to do is just stick to ported. I have a feeling that that sub is not suited for a 6th order and it would be dissapointing. I think that no matter what kind of box configuration, volumes and ports you do, the ported would easily beat it.

Again, this is just my opinion and you can take it with a grain of salt.

If you do build it, it would be nice to see the results either way.

I was thinking the same thing as well...

Well, I'll definitely be building it, just to see if I do gain anything at the meter. So I'll post some results when I get it metered, whenever that may be.

The sub itself has a pretty high EBP, which, from what I've heard, suits it well for ported and 6th order boxes. Whereas low-EBP subs work better in sealed and 4th order BP boxes. What exactly makes a woofer more suited towards a 6th order BP design?

IMO the sub is more suited for a 4th order than a 6th. The reason I say that is because of the QTS value it has, I looked at the specs you posted in the classifieds. Its QTS is 32. If it was lower then you could throw it in a 6th order. Also what frequency are you shooting for?

Between 54-57hz, my truck peaks at 55-56hz. I tried modeling up a 4th order BP, and I can get a 2-3db higher peak with it...is it really worth it over the 6th order design I originally posted in here?

Well could you do me a favor and put up a screenshot of the values in winisd because the peak you get in a 6th order graph seems very high and unlikely.

values of the box, or the sub?

Sorry for not being specific. The window where you enter the parameter of the sub. Like fs, Vas, Qes...etc

Hopefully you can see that...

Well, now I see it. I'm a little tired right now and work early in the morning. I will play around with it later though.

Maybe if I actually had the sd and BL it'd change the response?

Hmmm. I have the newest version of WinISD and it comes up with an error message when I try to save the values. Well I will try again later.
