Hey guys, I'm just wondering what you guys would recommend as far as enclosure specs if I am doing a strictly SPL box for a competition. Will be powered by an Orion 2500D at .5 ohm with plenty of electrical to back it up and the enclosure will be in the TRUNK.
I've been crunching some numbers on WinISD and seeing what volume and port length I'll need with a single 4" or 6" aeroport. With a 6" aeroport it says port length needs to be 4.59." Will a 4" suffice? A 6" sounds like it's more on par with the standard of port area per cube. Of course, it will want to be tuned relatively high, so I was thinking maybe 50 or 55Hz. When doing so, the graphs on WinISD show a massive peak of +9.0-9.4dB near 64Hz. The gains quickly drop off once you start going past 2.5-2.75 cubes..
In that case, should I just do a 2.75 cube box net, with the aeroport mounted externally and cut to the length of 4.59" WinISD tells me? Or does port length start changing when going external? Any thoughts on 4" vs. 6" aerport?
Thanks a lot,
Here is the woofer, and if any more info is needed just LMK and I can look in its manual:
