eric78702 Posted June 8, 2011 Author Report Share Posted June 8, 2011 I am gonna be running the saz-2500 on a single nightshade v2 18 what would y'all recommend on box size? Quote Link to comment Share on other sites More sharing options...
Nightshade Posted June 8, 2011 Report Share Posted June 8, 2011 4.5 cubes after displacement with 2 6" aeroports tuned to whatever you want it to. If you give me a freq you want to be tuned to I can tell you how long to make the ports. The 2 6" ports will give you 12.56sqin of port per cuft and should work out great. The 4.5 cubes is a bit on the smaller side of things but should allow your sub to take the 2500d all day long at pretty much full volume unclipped of course with no issues at all. If you were to go much bigger on the enclosure I think you might run into trouble with the sub getting hot over time at high volumes. If this is going into a hatch or a suv I'd see no reason why you won't be able to do 150's out of this setup. Depending on what vehicle too I'd say woofer up and port back or woofer up and port to the driver's side should work out best.

I want the lows to slam so between 33 or 32hz would be good I'm guessing. Quote Link to comment Share on other sites More sharing options...
eric78702 Posted June 9, 2011 Author Report Share Posted June 9, 2011 (edited) Anyone else have any suggestions on how big I should make the box with that power? Edited June 9, 2011 by eric78702 Quote Link to comment Share on other sites More sharing options...
C-Fizzy Posted June 9, 2011 Report Share Posted June 9, 2011 Nightshade is pretty much spot on. I have a box for two NS18's, 8.25 cubes net. The 18's were on an atomic 7k. Smaller box if you plan on using more than rated RMS Quote under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy?

C-Fizzy Posted June 9, 2011 Report Share Posted June 9, 2011 I think that sounds good. Quote under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy? Link to comment Share on other sites More sharing options...
eric78702 Posted June 9, 2011 Author Report Share Posted June 9, 2011 I think that sounds good. Because with the 2500 6ft^3 would be a little on the big side wouldn't it? Quote Link to comment Share on other sites More sharing options...
