View Full Version : Trying to make box as small as possible for TC LMS-R12

Ideal ported applicaiton TC Sounds says:

2.5 cubes
31" port length
2x4 port area
tuned to 30htz

12.6" diameter
11.2" cutout
7.2" depth

My measurements are
42" max width
19" max height
30" max depth

I would prefer the box use the full 42" width and as much of the height as necessary but keep it as shallow as possible so I can still put stuff in the back of the trailblazer. For some reason though when messing with the RE box calculator I can't seem to make it right.

Any help would be greatly appreciated.

Box Designers; how does this sound?

Width: 42"
Height: 18"
Depth: 10"
Wood: .75"
Square port height: 16.5"
Square port width: 2"
Square port length: 7.25"
Square port length 2: 20"
Total port length: 31"
Port Diameter: 6.48
Square port area: 33
Box Volume: 2.68 prior to displacement
Freq: 30.4

Driver is a 12" TC LMS-R. I am trying to keep this box as shallow as possible as it will be placed against the back seats in the rear of a Trailblazer SS. Hoping with only 10" of depth while using max width I can retain some cargo room.

use a 4" aero port with an elbow. slot ports are too big for enclosures smaller than 2.5 cubic feet.

Well this box is just over 2.5 cubes and looks like the port isnt too long where it will interfere with the depth mounting of the sub, no?
