I know this should be in custom fab but there isn't much going on there so ill post here. Can someone do a design for a 12" mach 5 ixl about 2 cubes at 38hz. I listen to mostly rap and its going in a sedan. Width max is 30 minimun is 24 Height has to be 14 and depth is the variable. If a couple corner braces could be included that would be nice, thanks guyss
I've been really busy for the past two weeks, so I apologize for not responding sooner. Can you supply me with a link to the specs of that woofer please. So if we use 30-wide by 14-tall by 16-deep, we end up with an internal volume of about 2.9 cu ft. As long as that woofer can handle that amount of volume (it should be able to) we are in good shape I'll work on port tuning in a minute
you could always play with the box builder program from RE, i've built 2 different boxes using it and i loved it http://reaudio.com/speaker_box/LPort_Box_Calc.html
I have BassBox Pro and WinISD. Yet I still prefer the TI-84 Calculator. I really like to practice my math skills. In Order to stay proficient at math, it needs to be practiced. Now for the port, It will be 12.5-inches tall and 2.5-inches wide. The length of the port will be around 22 inches long. This should put your tuning around 36 - 38 Hz.
Port tuning r is the port radius in inches, Vb is the box volume in cu in and Fb is the frequency we wanna tune the port to
if you are using a square or rectangular port and need to know the round port equivalent, then take the cross sectional area divide it by 0.7854 and then raise that result to the (1/2) power. Divide by 2 and we have r
