3vil Posted December 11, 2016 Report Share Posted December 11, 2016 Did you say the port on that port is only 7.5" deep? I'm on a phone right, how high is that box tuned? Link to comment Share on other sites More sharing options...
DLHgn Posted December 11, 2016 Report Share Posted December 11, 2016 I'm guessing it's tuned to about 35 - 40 Hz depending on how much net volume there is Link to comment Share on other sites More sharing options...
3vil Posted December 11, 2016 Report Share Posted December 11, 2016 Like I said I'm on a phone so my math could be really jacked, but I'm getting something in the 50-51 hertz range. And my math didn't account for woofer displacement. Link to comment Share on other sites More sharing options...
DLHgn Posted December 11, 2016 Report Share Posted December 11, 2016 Nah, with a box that large it would be lower. 132.25 in^2 of port. I figure about 2 ft^3 for each 12. @ 7.5 in long that would be about 36Hz Link to comment Share on other sites More sharing options...
Strokerjoe Posted December 11, 2016 Author Report Share Posted December 11, 2016 So it is tuned to wrong specs should I change the length of the port or just build a new box just don't really want to build 4 till I get it right Link to comment Share on other sites More sharing options...
DLHgn Posted December 11, 2016 Report Share Posted December 11, 2016 What do you mean build 4? Build a box for all 4 subs? Link to comment Share on other sites More sharing options...
Strokerjoe Posted December 11, 2016 Author Report Share Posted December 11, 2016 Lol the box I have now is tuned to low I take it . I was just saying I didn't want to build 4 boxes till I got it right. Link to comment Share on other sites More sharing options...
DLHgn Posted December 11, 2016 Report Share Posted December 11, 2016 I wouldn't say it's tuned too low. Depends on the subs and your taste in music/goals for the setup. What kind of music do you tend to listen to? Link to comment Share on other sites More sharing options...
Strokerjoe Posted December 11, 2016 Author Report Share Posted December 11, 2016 Rap and hip hop mostly Link to comment Share on other sites More sharing options...
DLHgn Posted December 11, 2016 Report Share Posted December 11, 2016 Then you'll probably want to be tuned about where you are if not a bit lower. Again, also depends on the driver itself. They most likely recommend it be tuned at 49Hz because that is when it will be loudest in their recommended box size. Problem with that is you'll likely see the response roll off pretty high and your cabin can only boost so much. This is good for listening to bass guitars or kick drums but most hip hop/rap have beats that go lower than that. If you really wanted to you could make a box with an adjustable port that way you could dial it in to what you want. Link to comment Share on other sites More sharing options...
