I should have read your first post better. This type of enclosure alignment is not suited for your goals. Regardless of what enclosure alignment you do use, I'm extremely skeptical that the driver will be able to be used up to the 90hz region with good results. If you truly want a flat response and wide FR than stick with sealed or ported enclosure with low tuning. Model the driver in multiple sealed enclosures within Fi's volume recommendations, do the same with ported enclosures and low tuning, and see which appears to meet your goals (flat frequency response, output). -
You can manually calculate port length with: Note that enclosure volume is net, and in cubic inches, so multiply your volume in cubic feet by 1728 to get cubic inches for Vb. Port area has to be converted to radius of circle in inches. Since area of circle is pi*r^2, you can translate your port area in squared inches to radius of circle by dividing by pi, and square rooting. IE: 2.92ft^3 volume and 24in^2 port area, 30hz tuning 2.92ft^3 x 1728 = 5045.76 in^2 24in^2 / 3.14 = 7.64, square root of 7.64 = 7.64^0.5 = 2.76in radius Lv = [ (1.463 x 10^7 x (2.76)^2 ) / (30^2 x 5045.76) ] - 1.463(2.76) = 20.5 inches. So with the net volume of the enclosure being 2.92ft^3, 24in^2 port area, and 30hz tuning, the port length would need to be 20.5 inches. The displacement of the port is portarea x port length, or 24in^2 x 20.5in = 492in^3 or 492in^3 / 1728 = 0.28ft^3 So the internal volume of the enclosure after driver and bracing displacement needs to be 2.92ft^3 + 0.28ft^3 = 3.2ft^3 or 2.92ft^3 with an external port. I hope that sheds some light on the topic.

That's awesome. Check out Youtube tomorrow maybe.
This is sad.
I was reading a chem book earlier about thc extraction, and I just checked digg.com to see: http://the-magazine.org/23/potpourri#.Ug2sovVuV7h What the odds...
8tracks.com is my favorite site for music streaming. FUCK YOU Pandora et al.
Wow man I completely forgot. Is it okay if I send it this weekend? Like I said I'm in no hurry as long as it isn't an inconvenience to you. Yeah, otherwise I'll forget about it.
You gonna send me that hdd Rick?
The usb gps dongles are inaccurate?
You going to do any mods? I kid.
Does she work for the govt?
We had a black jetta and the neutral safety switch went out twice and the computer once. After the computer went out we sold it, and a few years later VW acknowledged there was a problem with the neutral safety switches going out.
Weird. I don't see anything bad about chrome.
Even running sounds dangerous, unless you're on some trail. It's pretty cool how quiet they are though!
I'm not paying attention lol.
Which will make no money to speak of. Better off signing up with Itunes or the alike.
