pRoFsWiRlY Posted February 9, 2010 Report Share Posted February 9, 2010 Just want to make sure that I'm getting this right, because I'm going to be attempting my first ported box build. Heres what's going in... 2 Memphis 15-M310d4's Memphis 16-mc1.1100 Box Dimensions: 37x19x10.5 (3/4" mdf) 3.02' after sub displacement Port: 11"x2.5" 8" long tuned to 37.11 hz For all you port gurus with tips or suggestions, please chime in. just want to get this done right and planned out before my first cut. This is going into my scion xB and will be making a second "false" port for the look of a toaster. Thanks for any feedback!

Thanks for any feedback! i cant imagine those 15's only needing 1.5 ft. each ported.. am i missing something? i had my single re 15 in 3.3 at 33hz and it did well, i would go exactly to manny specs for the driver, and then go to the re box calculator and tweak it till you get what your looking for. easiest way to figure it out to me...i dont know much but i've done enough to know if i was doing two 15's, i'd want at least five feet, with the port tuned to whatever you want, vehicle tune, manny spec tune, or favorite tuneage, like 33 but every car is dif. pics please and good luck! ya those measurements are too small bro, i just did this one yesterday...r<a href="http://s376.photobucket.com/albums/oo205/meatstick_2008/?action=view¤t=100_0370.jpg" target="_blank"><img src="http://i376.photobucket.com/albums/oo205/meatstick_2008/100_0370.jpg" border="0" alt="Photobucket"></a> Quote Link to comment Share on other sites More sharing options...

Kranny Posted February 9, 2010 Report Share Posted February 9, 2010 9.1sqin of port per cubic foot isnt enough. you need at least 12-16. 14-16 is recommended. btw you increase it by making the port opening bigger Quote Link to comment Share on other sites More sharing options...
