schwarzl Posted April 7, 2018 Report Share Posted April 7, 2018 Hi, been out of car audio for years. I'm getting back into doing a mini system with some random stuff I have collected. I am using Torres box calculator and trying to figure out how big to cut my port pieces for a Slot Port. I'm using to Massive Hippo 8's. I want to use a 1" Baffle so I put the extra baffle as 1 and the baffle thickness as .5, the calculator didnt want to seem to move by entering just 1 in the thickness, it stayed the same as .75, as in the volume didn't adjust at all. Thanks for any help. Link to comment Share on other sites More sharing options...
Joe X Posted April 8, 2018 Report Share Posted April 8, 2018 Can't have 0.9 cubic feet of sub displacement, also the box external dimensions did not get captured. Link to comment Share on other sites More sharing options...
schwarzl Posted April 8, 2018 Author Report Share Posted April 8, 2018 Sorry, it's 14" high, 40.75" wide and 15" deep. I cut the one port piece at 10.125 and the other at 18.75. Link to comment Share on other sites More sharing options...
Joe X Posted April 8, 2018 Report Share Posted April 8, 2018 Use driver displacement = 0.2, # of common port walls = 3 (non shared port) and leave blank or zero the # of extra baffles unless you are doing a double layer baffle. Then you can see about the length of your port parts. Link to comment Share on other sites More sharing options...
schwarzl Posted April 8, 2018 Author Report Share Posted April 8, 2018 Thanks for your help, unfortuantly I have zero patience and built the box already. I used .9 cubes of displacement when it should have been .09 cubes. So if I worked it out right, I've now got a box thats 2.85 cubes tuned to 27.5 hz.... At least I work at a cabinet shop so I can just remake another box. So this is what I worked out for the next one. For some reason it cuts the top off the image. The dimensions are 15" High, 37" wide and 11.5" deep. So with these new dimensions is the physical port length the length of the walls for the slot port? So I would have one piece cut at 7.5" x 13.5" and the other at 24.25" x 13.5"? Link to comment Share on other sites More sharing options...
Joe X Posted April 8, 2018 Report Share Posted April 8, 2018 LIke this for a 35" center line length: Front to Back = 7 1/2 x 13 1/2 Extension = 23 1/2 x 13 1/2 However your port height is 12.5 in the Torres just above. Link to comment Share on other sites More sharing options...
schwarzl Posted May 5, 2018 Author Report Share Posted May 5, 2018 Alright, things have changed a little. I am now awaiting the arrival of two more eights. So I have come up with this new box design and just want to confirm that I will be cutting it correctly. So the first part of the port that will be attached to the double baffle will be 13.5" high and 11" deep (plus the 1.5" baffle would make that part 12.5" total), and the attaching length would be 13.5" high and 23.25" long. Am I getting that right? Link to comment Share on other sites More sharing options...
