Collin Hagewood Posted October 22, 2014 Report Share Posted October 22, 2014 Ok im know with the "L" port design my numbers are correct and it is tuned perfectly, but i have 2 other port designs that im considering. I really want a port in the middle of the box ( for looks, and looks like it may be stronger)....I understand that removing the internal bracing will have a minor affect, but I need to know if the ports will come out to the same tuning(all I did was place the port in the middle and split the difference for the "T".....the "L" was 7.5", and each side if the "T" is 3.75"...Thanks for your help 48x16x16, Tuned to ~35hz and about 4.70ft^3...going to fire up and port back in a 03 yukon Pictures of the boxes "L" port http://i1135.photobucket.com/albums/m632/bobob07/NewsubLport.png?t=1413949153 Idk what this would be called http://i1135.photobucket.com/albums/m632/bobob07/Newboxwithportwanted.png?t=1413949417 What im calling a "T" port in the middle http://i1135.photobucket.com/albums/m632/bobob07/TheBestBoxever.png?t=1413948730 Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted October 22, 2014 Report Share Posted October 22, 2014 One thing I see wrong with the t shaped port you have is that you have to width constant the whole way. Say you have 4 in port going into each chamber you would want where they join together to exit the box to become 8in wide That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Collin Hagewood Posted October 22, 2014 Author Report Share Posted October 22, 2014 Not understanding this 7 - Port length uses the box wall or baffle(s) as part of the port length. So a port that is 10" long with one baffle using .75"wood will only need to be 9.25" long since the box wall or baffle(s) will account for the other .75". If using two baffles,then it would be 8.5" long as the baffle will account for 1.5" of port length and so on. Link to comment Share on other sites More sharing options...

Collin Hagewood Posted October 22, 2014 Author Report Share Posted October 22, 2014 lol you cant put in a number of ports or it registers it as a round port....there is no check box for round port, the one you posted Link to comment Share on other sites More sharing options...
islandpride684 Posted October 22, 2014 Report Share Posted October 22, 2014 You leave those blank, just need height, width and length, you need those if you are doing round ports Build Log http://www.stevemeadedesigns.com/board/topic/186921-blk9te-07-yukon-slo-mo-build/page-3?hl=%2Bblk9te#entry2881410 Link to comment Share on other sites More sharing options...
