Decaf Posted December 17, 2011 Report Posted December 17, 2011 maybe post pics of torres screen shot? could be something you made a mistake on that messed up ur tuning..also pics of the box installed could help if the box itself isnt doing it? this I know people that peak below their tuning frequency. Just a strange phenomenon. in car tuning usually drops, most with suvs its seems when the port fires back. if this help my 4th order peaks below tuning thats different... and common in 4ths
kirill007 Posted December 17, 2011 Report Posted December 17, 2011 How do you know for sure that your car peaks at 51hz? Because your previous boxes peaked there or what? Going from the sketchup, it seems about correct, or maybe a bit too long, but i'm guessing so that means nothing at all.(im not that pro that i can guess tuning by just looking at the box ) Thinking is the root of all problems... You ALWAYS get what you pay for.

I know a FEW things, not all, probably not most, but a FEW things 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals
Decaf Posted December 17, 2011 Report Posted December 17, 2011 so u put 1 hdc3 10" in a 1cuft sealed box? u don't just stick any sub into a 1cuft sealed box and expect its response to be flat on all frequencies. your 51hz peak is not right at all likely, that's just where the sealed box peaked at
kirill007 Posted December 17, 2011 Report Posted December 17, 2011 Like decaf said, you don't just put a random sub in a 1cu ft sealed enclosure and it will tell you the peak. But it could also be because you are much louder with the ported box, and the peak frequency drops, but it should drop almost 20 hertz. Thinking is the root of all problems...

Decaf Posted December 17, 2011 Report Posted December 17, 2011 you got less than 20 responses and you're already giving up because someone questioned how you got 51hz... wow is the dual 10" box sealed off firing forward?

We just need the correct circumstances to know what's going on, nothing else going on. Thinking is the root of all problems... You ALWAYS get what you pay for.
