Afficionado Posted March 10, 2013 Report Posted March 10, 2013 I'm doing a big box, not a wall in the back seat of my corolla. Now i am trying to decide whether to do 2x 18's or 3x 15's. I think the 2x 18's will be easier to do, though they will have slightly less surface area. my goal is to move as much air as possible, and i don't plan to ever meter it. opinions? also: i'm using torre's box calculator. I easily found how to get the desired tuning frequency i wanted, but i want to make sure i'm doing everything correctly. a 7x7x8 port will put me at around 28 hz after woofer displacement. is that fine? If you have any questions relating to nutrition, lifting, or health in general, feel free to give me a PM and I will give you straight forward advice with no BS involved.

Krakin Posted March 11, 2013 Report Posted March 11, 2013 Your port area per foot should be 12~16 square inches 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.
Afficionado Posted March 11, 2013 Author Report Posted March 11, 2013 Your port area per foot should be 12~16 square inches how can i do this and still achieve a very low tuning?

Krakin Posted March 11, 2013 Report Posted March 11, 2013 Extending the port length and shortening the width and or height of the port. Other than that you gotta just keep messing around with torres 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?

Afficionado Posted March 11, 2013 Author Report Posted March 11, 2013 whenever i get close to a size that will fit what i need, it says the cut-outs are too complex to display.

Afficionado Posted March 11, 2013 Author Report Posted March 11, 2013 also. if my box depth is 24", is there a general distance you want to keep your port away from the back of the box?

Krakin Posted March 11, 2013 Report Posted March 11, 2013 For if the box is too complicated I normally just design it myself (almost always). And as a general rule you need the port at least as far away from the back as the height or width of the box. Gimme a bit and I'll upload a picture or two talking about what I mean.
