Joe X Posted December 6, 2013 Report Share Posted December 6, 2013 If you are going with a slot port in the baffle better do a rectangular box, it's harder to turn the port on a slanted surface. Link to comment Share on other sites More sharing options...

Hey Joe Don't worry, I did my homework lol. here's what I got: Box volume: 4.26 cuft Port volume: 1.15 cuft (91.5 cms port length) Box volume - Port volume: 3.11 (this is for a inverted mounted VVX15v2) 14,30 sqin/cuft for the inverted sub, 15,18 sqin/cuft for the normal mounted sub (2.93 cuft net) Inverted mounted gets a 30.4Hz tune and the normal mounted gets 31.3Hz tune This is be the box I'll build, thanks for all the support you gave me guys!

[email protected] Posted December 6, 2013 Author Report Share Posted December 6, 2013 This is the chart acording to winISD blue is the IVX15, red is normal mounted VVX15 and yellow is inverted mounted VVX15 I'l just mount it normal cause there isn't a significally difference between inverted and normal.

Joe X Posted December 6, 2013 Report Share Posted December 6, 2013 The effective length of that port will likely be less than the what the center line would suggest and the port will be inefficient to say the least. probably could be laid out differently. I can't see what your port area is so I can't give you feedback on that. Link to comment Share on other sites More sharing options...
[email protected] Posted December 6, 2013 Author Report Share Posted December 6, 2013 Port is 7 cms width and 41 cms height port area is 15,18 sqin/cuft for 2.93 cuft net why you say it's inefficient? it's because is next to the driver? Link to comment Share on other sites More sharing options...
Joe X Posted December 7, 2013 Report Share Posted December 7, 2013 Your port area is a little low, nothing serious but near 50 square inches would be better. Link to comment Share on other sites More sharing options...
Joe X Posted December 7, 2013 Report Share Posted December 7, 2013 I say the port is inefficient due to all the turns it has, the least bends the better. Link to comment Share on other sites More sharing options...
[email protected] Posted December 7, 2013 Author Report Share Posted December 7, 2013 Hi joe, I hope this one is a lil better Net volume (after port vol and sub displacement): 2.83 cuft Port lenght is 98 cms (I get 31hz tune acording to winISD) and port has 15,77 square inches per cubic feet tell me what you think (bigger box is a no option because I use my trunk a lot to carry stuff, this is the biggest box I can have right now :/ ) Link to comment Share on other sites More sharing options...
Joe X Posted December 7, 2013 Report Share Posted December 7, 2013 The fact that is square makes it gain efficiency, still it has 3 turns (one 180 deg), BUT I have to say that I have yet to see another 3D center line laid out port, very nice. I would need to draw the whole thing to tell you about the tuning but due to the multiple turns it will be higher than expected going by the center line.
