thaxton Posted April 26, 2011 Report Share Posted April 26, 2011 I recently hooked up a system in my girlfriends car. Nothing major, its just an older punch 500-2 and a punch p3 12. The sub came in a tiny sealed box (bought it secondhand), and I can't stand the weak output it has (Its also got crap for low end). I know this woofer could do alot better in a proper box. I was just wondering if someone who has experience with bandpasses thinks this would be a decent speaker for a 4th order? If not, I will just build a regular ported box. Any suggestions?

RAM_Designs Posted April 26, 2011 Report Share Posted April 26, 2011 (edited) It'd help if you'd post the t/s or a link to them. But from what I remember, the P3 is a decent sealed box/4th order BP type of sub. The sealed box you have is probably just too small. BP will definitely give you a lot more output though.

thaxton Posted April 27, 2011 Author Report Share Posted April 27, 2011 The speaker is in a 1 ft box, so it is within Rockford's specs, it just has that tiny sealed box sound which I am not fond of. This is what I found on the Rockford website. I hope that this woofer will work for a 4th order, I have built sealed and ported boxes before but I have been wanting to do a bandpass for a while.

fecupe2001 Posted April 27, 2011 Report Share Posted April 27, 2011 Ram, what exactly are the parameters you need to take a look at if you are thinking of building a 4th order?? i see everybody doing 4th orders this days on any sub so that's why i'm curious, i;ve designed a few and they have worked AWESOME on every sub, maybe i was lucky, i would love to know this for sure, thanks man...

SGTSKIP Posted April 27, 2011 Report Share Posted April 27, 2011 I put a pair of RF 10's in my girls car running off of a R500-1, they came in a prefab box that I hatedso I made up a ported 1.5 ft box and it woke them up. Try a ported box b4 the bandpass. 1. Ported will give nice output 2. Smaller and easier to build 3. If not happy, do the bandpass Good Luck Steven Quote Does this smell funny to you?

jizazz12 Posted April 27, 2011 Report Share Posted April 27, 2011 Throw it in a ported box and that sub will come alive, i had two p312's in a ported box and i installed two of the same subs in my buddies car same power only differences his was sealed , built the boxes to Rockford's specs his sounded good but had the same issue was lacking on the low end.

fecupe2001 Posted April 27, 2011 Report Share Posted April 27, 2011 maybe just for testing, you could open a hole and get a crappy pvc tube externally hehe, i did that on a test and gained a huge lol, you are throwing the box to the garbage anyways so you could do something fun with it first Quote I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

thaxton Posted April 27, 2011 Author Report Share Posted April 27, 2011 (edited) Thanks for the responses guys. What kind of airspace/port area would you guys recommend for this woofer?

Maybe some 4 inch PVC? Quote Link to comment Share on other sites More sharing options...
