On winISD, the two 8" ports keep velocity higher than 40m/s, and the 10" dropped it down to ~34m/s. The frequency response peaked hard at tuning, but i think that was due to crappy t/s from crescendo, or just winISD being picky. then the program crashed on me and i stopped there. while you may want to make the enclosure a little larger to compensate for your power-to-sub ratio, larger = peakier. My personal preference is to stick to the smaller side of net volume for a wider bandwidth, but to each his own. More port area is needed for sure though in order to keep port velocity and noise down. two 12" ports puts you just below triticums optimal area. This is what I got if decided to buy 8in ports (since no clue if my 10in ports even exist anymore ) Link to comment Share on other sites More sharing options...
Thomas1994 Posted March 2, 2019 Author Report Share Posted March 2, 2019 I'm guessing there is no logical way to get 2 10in ports to work haha Close as I could get then numbers started turning red Link to comment Share on other sites More sharing options...

reedal Posted March 2, 2019 Report Share Posted March 2, 2019 Its not enough port area. You will be restricting the flow, which can create port noise and will reduce output. You may be better off with a slot port SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...

You may be better off with a slot port Just kinda sucks I have 2 10in ports sitting here and spent almost $150 on them... That's about as close as I got You can't even buy the subs anymore so adding a 4th one isn't a choice (nor is financially possible for me) Also I know you said on paper it probably does more but one of the audio groups (mwspl or ispll don't even remember been a year since asked) has it doing 6500w. Now I do believe the v2 does more then 6500w dynoed but I have the ns1 v1. So hoping maybe to get 1500w per sub, about 1000w under powered per sub...

Thomas1994 Posted March 2, 2019 Author Report Share Posted March 2, 2019 Now its in the red lol Port area 157.08in2 Port area per foot/liter 13.7in2 (but showing red) Total net of the box 11.46 5 hours ago, reedal said: Its not enough port area.
