hispls Posted December 4, 2014 Report Posted December 4, 2014 Thanks for your help, and had seen the box designs ddaudio.com but the problem I see is that they are generic designs, and this sub with Fs: 44.41hz seems special. any other suggestions? I suggest you re-read the DD website, their design philosophy and use their recommended box specs. Or if tl:dr, they only build and sell woofers that work well in those boxes they recommend. Your EBP is at 44.98(45). The sub you have is best suited for a sealed enclosure. IF you want to ruin a ported box with that sub, it's not ideal at all. IF you want to run it ported, I'd suggest a higher tune, close to 40Hz. Which is pretty much the cookie-cutter DD box,
CleanSierra Posted December 4, 2014 Report Posted December 4, 2014 I agree, but the sub they've CHOSEN to use for a 12" in that 2500 serious has an incredibly high electrical Q. I don't know what made them continue on with that design. I'm truly not bad mouthing, but perhaps they should just be full disclosure and advise that the sub is best for a sealed box(at least the 12"). P.S. I agree with you, that's pretty much on par for a DD sub, high tune. Im not the one you want to try to troll. Just a fyi for you.

CleanSierra Posted December 5, 2014 Report Posted December 5, 2014 You used the striker got the hatch as your ground? You shouldn't use that as a ground. So wait, you were asking questions about enclosures yesterday and you've already made a box? I'm curious how it will sound. Im not the one you want to try to troll. Just a fyi for you.
Eclipse25 Posted December 5, 2014 Author Report Posted December 5, 2014 I did not the box, send it to make. dimensions are 34in x 16in x 12in. The port: 3 in x 14.5 x 19.5in. Sound good but much "plac" for me. Its tunning around 44hz, i want to play sound 30hz or 35hz bass.... Its raining now. Coming soon video
CleanSierra Posted December 5, 2014 Report Posted December 5, 2014 I don't understand what you're saying. I know there is a language barrier, but I don't know what "plac" is. Im not the one you want to try to troll. Just a fyi for you.
Krakin Posted December 5, 2014 Report Posted December 5, 2014 You won't play 30 hz tuned to 44. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
