Does anyone know any sites that have the blueprints for various enclosures?

 

Don't necessarily have blueprints, but if you go to JL audio's webpage that "tutorials" to box building techniques and practices.

Polk used to give blueprints for their speakers in specific enclosures, but I don't know if they still do that or not.

Most likely you are going to have a hard time unless you look for those designs for your specific subs. There are too many variables to have specific blueprints for all subs.

 

Way too many variables for every car, every sub, etc. And the all important "Me" factor. That's the most important thing when custom building a sub. The fact that it sounds great because you designed it that way. I recommend you read at least one of the following: Great Sound Stereo Speaker Manual, David Weems, or The Loudspeaker Design Cookbook, Vance ****ason. Both are widely recognized as excellent starter to mid level enclosure techniques. And farely easy reading. If you don't have 20 credits of calc then skip those sections and rely on others for crossover design and construction. I do that even with around 20 credits of calc just because I don't use that math now that I am out of school.

 

Most go by the rule of 0.6:1:1.6 as a ratio of the sides for a ported box. Get the speakers recomendation for are needed and stick +/- 20%. Get some quality MDF board and screw in every inch. Be sure to seal your box well with caulk, and don't forget where the wires enter. If the box is to be ported get some PVC. For a ported box the size is not as important as with a bandpass. I've done a lot of experimenting with boxes and first I earned stick to the manufactures reomendations espicially if they give you box volume or an actual box size. Next important is a good seal and a strong box. As for the 20 credits in calc I'm 8 short.

 

umm...

L*W*H
----- =air space
1728

 

wont let me edit that for some reason ..

just wanted to say also add displacement of speaker and port (if neccessary)

 

This will give you box volume in cubic feet from the L,W,H when they are in inches.
12in/ftx12in/ftx12in/ft=1728ft cubed

is where the 1728 comes from.

If you use this use the inside box L,w,h, that is take away the width if the material. You only want to measure the air volume. And as loudmaxima said also subtract the volume of the port and speaker.

 

blaupunkt has a program u can download its called blau box it is a real simple box program... but u need the parameters of the speaker u have or goin to buy.... u can make a band pass box, sealed encloser, vented, and wedgeshaped...

 

I agree. My box is finanlly complete after 8 months of building. It was designed for the Sentra I had, but it will fit perfect in the Max as well. It is 1.5" MDF. I needed a min of 1" mdf, so we put 2 boards together all around a box, made it extra strong and thick and used screws, liquid nails as well, and caulk all around it. Its carpeted, and all I have to do is put the speakers inside of it. The bos is probably near 200lb though. A guess. I needed a box strong enough to handle my 2 12" Infinity Perfects pushing over 1200watts. They are going to be LOUD!

 

No, you don't "need" any calc. But don't expect it to sound optimal. Each speakers specs vary in general by at least 5-10%, and who knows if the manufacturer actually gave you the specs for the right speaker. The pro's, and the people of Madisound, actually test the parameters of speakers and crossover components for a smooth, accurate response. If you have a school physics lab you may have access to all the test equipment you need, other than the test box that you will need to build.

 

anyone has pics of custom enclosure in a 4th gen max?

 

recommend building fibreglass boxes for subs. I have mine in the rear quarters in the boot firing in. these work very well as they dont take much space. it is also air tight.

 

where is that exactly??? i'm planning out a design right now. what's the boot?

 

Down under for Trunk.

 

Hey Aussie,
Do you have any trouble getting the lid to close? I mean with the vents in the bottom of the quarters sealed?

 

If I were you, I would get a woodshop to build you one to your own specs.

 

That's kinda boring.
