Instinktas Posted September 12, 2019 Report Share Posted September 12, 2019 This is my first post and I hope not the last. From what I've been reading and some of you more knowledgeble been saying is that even a shitty sub in a good enclosure can outperform the greatest subwoofers in sub par enclosures. Right now I am running a rockford p2d2-12 in a stock box from rf powered by an R750-1D amp. It gets plenty of power and yet Im not satisfied with what Im getting. I know RF doesnt get much love here and its not a great sub but before I buy something else, I want to try a new enclosure. The recommended Vas by RF is 81.5 litres (~2.8 ft) and the stock box is only 52 litres so Im confident the enclosure is the problem here. I have ~4ft of space available for the box and I'd have no problem of using it all. The question is does anyone have a great design for this sub and if not, where do I start making it myself?

AaronT Posted September 12, 2019 Report Share Posted September 12, 2019 RF gets much love here The p2 is an entry level sub. Don't expect much. 4 cubes is not going to do anything but hurt that sub. Recommend sealed is 1.02 cubic feet Recommend ported is 1.79 cubes tuned @ 40 hz. Vas is not translation to box volume Link to comment Share on other sites More sharing options...

Vas is not translation to box volume Then Ive been reading too many bad posts about RF. If thats the case about this sub, I guess its time to upgrade. This is a total change of topic. Is there anything you could recommend for this amplifier that would really make me feel a difference? Im mainly looking for something that would make me feel those hard tight drum kicks like in concerts or beats in the chest like in the clubs. I really feel like my bass is lacking compared to T262S in the front for highs and 2 PPS4-6 in the back for mids. My budget is around 350$ for the sub, I can do little bit more if anything close comes up. I'd guess for my power and availble space a single 12" or 15" would suffice?

AaronT Posted September 12, 2019 Report Share Posted September 12, 2019 Nice components. I'm going to be installing 2 sets today actual. Did your budget, get a American bass xfl 12 dual 2 ohm. Give it 2.5 cubes ported @ 38hz. That amp is fine. It's underrated it's around 1k easy. Link to comment Share on other sites More sharing options...

Btw i knew rockford underrates but I had no idea i could be so much An xfl 12 with at least 1k in the right box will be a HUGE step ( or a few steps honestly) up from what u already have. I tried and beat the stitches out if my xfl on 2k and it just ate and wanted more. Phenomenal sub and a very good price for it.
