UhOh Spaghetioz Posted August 14, 2012 Report Posted August 14, 2012 Just got a new sub. A dad kmh 12 and man is this thing badass. Ive always used prefabs in the past but this time i wanna do it right since i have a nice sub. I was wondering if i could get some help with a design. The owner of dad says they tune anywhere from 32-45hz. I was thinks maybe a 33hz tune. And the internal volume is usually 1.3 cubes. The displacement of the sub is 0.15. I already have a 4" aeroport i want to use because of the small trunk space i have unless i can fit a slot port box in there. My max dem are 14.25h 28w 13.5d. The sub will be on 500 rms. Thanks for the help

Joe X Posted August 14, 2012 Report Posted August 14, 2012 Well here is a suggestion, researched the sub a bit, this is what can be done on your dims: Enclosure Specifications: Fb = 33 Hz Vb = 1.75 ft^3 External Height = 14.25 in External Width = 28 in External Depth = 13.5 in Port Width = 1 3/4 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 25 1/2 x 12 3/4 Back = 28 x 12 3/4 Left & Right Sides: Side 1 = 12 x 12 3/4 Side 2 = 12 3/4 x 12 3/4 Top & Bottom = 28 x 13 1/2 L Port Internal Assembly Parts: Front to Back = 10 1/4 x 12 3/4 Extension = 13 1/8 x 12 3/4 Assembly guide (generic dimensions): Let me know any questions.

Awesome. Thanks man. Did you use the torres calculator to figure all that?
Joe X Posted August 15, 2012 Report Posted August 15, 2012 You can use Torres to verify the results, port centerline length is 26.2/3".
UhOh Spaghetioz Posted August 30, 2012 Author Report Posted August 30, 2012 You can use Torres to verify the results, port centerline length is 26.2/3". What kind of displacements were included? Like for the sub and the two 45s in the pic?
Joe X Posted August 30, 2012 Report Posted August 30, 2012 One of the 45s has no displacement as is in port airspace the other is 0.01 cubic feet the sub 0.15 cubic feet.
