| Back a couple years ago I used some great info from this Forum and built a slot ported box using a program that was great. It was web based, you put in your dimensions and the sub info as well as the frequency you want it tuned to and it spit out actual plans for you.
I tried the links for this and they don't seem to work anymore, does anyone have any suggestions/links? |

| The REAudio one is exactly what I want but I have to give it the port width and length which I don't have...... How do I figure this out? The other one you would give it the Frequency you want it tuned to and it would figure out port width and lentgh.
I'm sure there's a way to figure it out? I want a box that's 36" wide by 17" tall and it's for a single Fusion 12" Jonah Lomu:
fjl-1211 Jonah Lomu Woofer
* Magnet Structure 300 Oz
* Power Handling 1300 Watts
* Voice Coil 3" Black Alloy SVCImpedence (per coil) 4 Ohms
* Free Space Resonance (Fs) 28Hz
* Efficiency 89db
* Frequency Response 21Hz to 1.2kHz
* Mounting Diameter (mm) 11.22"/285mm
* Mounting Depth (mm) 6.49"/165mm | |
