Owen Hix Posted May 14, 2013 Report Share Posted May 14, 2013 Hey guys i am trying to build a box for either 2 skar zvx 12s orr 15s (havent decided on what ones i want but id rather have the 15s). But i cant figure out this slot port. Im using torres's box calc and if anyone could help for either set of subs i would really REALLY appreciate it. My max dimensions are 20H, 50W, and 15D, and i am looking to tune around 28 hz, and looking to stay between 10-14 sq^2 per ft^3. Displacement for the 12's would be .24 and the 15s is .3 I really appreciate any help. Thank you. Hope I'm not asking for too much of a favor. Edit: i guess mainly im looking to know the dimensions for the 2 pieces that make up the l of the port. -05 Chevy Colorado- Kenwood KDC-352U Headunit Skar VXI-65 front component speakers Polk DXi650 rear speakers Alpine MRP-F300 4 chan.

321slapinbass Posted May 15, 2013 Report Share Posted May 15, 2013 subs up and port across the bottom into the drivers side pillar. - 3/4" wood, double top baffle for subs - 4.1 cubes @ 31.8 hz (28 is pretty low for daily) with 14.7 sq in of port per cube box: 40w 19.25h 15d (5.61 cubes gross) port: 13.5w 4.5h 33d (displacement of 1.24 cubes) subs: displacement of .24 cubes 5.61 minus 1.24 = 4.34 4.34 minus .24 = 4.1 (4.1 is your net volume) the box is only 19.25h because of the double baffle which will make it a total of 20h, and the box is only 40w leaving 10" of space between the port and side of truck for the port to breath. 2000 Dodge Durango Subs - (2) SKAR VVX 15 D2's Box - 7.2 ft^3 @ 33hz, 120 in of port Sub amp - Digital Designs M2 @ .5 ohm Mids + Highs - PRV Audio Mids + Highs amp - Hifonics 2000.4 Headunit - Alpine CDE-100 Equalizer - Clarion EQS746 Batteries - Mopar group 27 + (2) C&D 52ah Wiring - 1/0 BIG 3, (2) runs 1/0 Alternator - Singer 250A 147.79 dB @ 35hz - burp - sealed on dash 147.47 dB @ 35hz - music - sealed on dash YOUTUBE: http://www.youtube.com/user/321slapinBass/videos Link to comment Share on other sites More sharing options...
Owen Hix Posted May 15, 2013 Author Report Share Posted May 15, 2013 thanks man. so i guess my next question, assuming the port has 3 common walls, all i need to do is take a board that would be 13.5w and 33 long and make it 4.5in off that bottom of the box? if i understood you correctly. sorry this is my first slot port build. lol -05 Chevy Colorado- Kenwood KDC-352U Headunit Skar VXI-65 front component speakers Polk DXi650 rear speakers Alpine MRP-F300 4 chan.

321slapinbass Posted May 15, 2013 Report Share Posted May 15, 2013 correct, you would leave 4.5" between the bottom of the box and the piece of wood that makes the port, leaving you with a opening that is 13.5 x 4.5 2000 Dodge Durango Subs - (2) SKAR VVX 15 D2's Box - 7.2 ft^3 @ 33hz, 120 in of port Sub amp - Digital Designs M2 @ .5 ohm Mids + Highs - PRV Audio Mids + Highs amp - Hifonics 2000.4 Headunit - Alpine CDE-100 Equalizer - Clarion EQS746 Batteries - Mopar group 27 + (2) C&D 52ah Wiring - 1/0 BIG 3, (2) runs 1/0 Alternator - Singer 250A 147.79 dB @ 35hz - burp - sealed on dash 147.47 dB @ 35hz - music - sealed on dash YOUTUBE: http://www.youtube.com/user/321slapinBass/videos Link to comment Share on other sites More sharing options...
