94jettameowpsst Posted November 8, 2012 Report Share Posted November 8, 2012 I feel like an idiot. What is a baffle? Will adding a 2nd layer to the top of my box where the subs mount effect the tuning frequency? The inside dimensions of the box won't change but I assume the sub volume will since it will be mounted 3/4 inches higher than the normal mounting depth. Sorry if this is a stupid question but I'm just trying to build it right the first time....3/4" birch sheets add up quick $$ 150.1 @ 38hz142.3 @ 20hz (windows down)Only 2 batteries Link to comment Share on other sites More sharing options...
wcefai Posted November 8, 2012 Report Share Posted November 8, 2012 Baffles are the faces of wood that hold the subwoofer. And yes, you are correct when it will affect displacement but that will be minmal, so it shouldnt affect tuning Edit: but if you are worried, just go to torres, make the box .75" taller and add a second baffle Link to comment Share on other sites More sharing options...
94jettameowpsst Posted November 8, 2012 Author Report Share Posted November 8, 2012 Also with the way I have my box it will be 9" from the back of my jeep w a tuning frequency of 36.8 ish and the port size of 12"x15"x15" w 180sqin of port. Should I change it to 11x15x15 to drop tuning to 33 and sacrifice port area or leave it how it is? 150.1 @ 38hz142.3 @ 20hz (windows down)Only 2 batteries Link to comment Share on other sites More sharing options...
Chris Hammer Posted November 8, 2012 Report Share Posted November 8, 2012 What kind of sub(s)/power are you building for. Double baffles have been a forum boner all over...but I see alot that aren't necessary. Whats your box like? slot port or aero and where is the port?

wcefai Posted November 8, 2012 Report Share Posted November 8, 2012 Use torres, it helps a lot with box design and just brainstorming ideas Link to comment Share on other sites More sharing options...

Should I change it to 11x15x15 to drop tuning to 33 and sacrifice port area or leave it how it is? I would drop it only if you cared about being lower... Im guessing with that much port area you are doing big subs so I would ignore my first post and do a double baffle and maybe some threaded rod too.

94jettameowpsst Posted November 8, 2012 Author Report Share Posted November 8, 2012 Port is a 0 common wall port, rectangular towards the bottom of the box Box is 17x41x47" and after displacement and bracing 13.7ish cuft. Ports centered in the back panel (opposite of subs) facing back w dimensions of 12/15/15 tuned at 36ish Running 2 aa mayhem 18s on a 4500d Going into a jeep cherokee country. I was going to possibly have the port firing forward and the subs by my hatch as they fire up and add a 2nd layer on the top of the box where the subs mount and secure my amp to the top of the box. I hope this is clear bc idk how to post pics from my phone 150.1 @ 38hz142.3 @ 20hz (windows down)Only 2 batteries Link to comment Share on other sites More sharing options...
wcefai Posted November 8, 2012 Report Share Posted November 8, 2012 Youd most definitely want a second baffle. And most people run subs up, port back. and either port will work, tuning is your preference Link to comment Share on other sites More sharing options...
