NickTheBassHeadCook Posted February 19, 2012 Report Share Posted February 19, 2012 I recently decided to upgrade my system and get 2 AQ HDC315s running off an AQ2200D. I drive an 07 Trailblazer, I need a vented box design for them. The MOST room i have is 44"(W) 18"(H) 26"(D). I want it tuned around 34-35 Hertz. Someone help me out. Also, I cant decide whether to go with the 12s or 15s. Any advice on this? I think the 15s would have plenty of space, but ive never ran AQ before so im not really sure.. someone help me out please.

Decaf Posted February 19, 2012 Report Share Posted February 19, 2012 you would want 8-9cuft net, your max dimensions with 1 layer all around and a double baffle leaves you with 9.49cuft. each subs displ is roughly .25cuft. so you are down to 9cuft without even adding a port. port would be roughly 130sqin give or take, to achieve 34/35hz tuning you are looking at over 1cuft port displacement then you need bracing, which will take up another .1-.3cuft depending on what material you use in other words, you dont have enough room Quote Link to comment Share on other sites More sharing options...
Joe X Posted February 19, 2012 Report Share Posted February 19, 2012 The DC Audio XL 15" can work on 3.25 cubic feet each, much more feasible on your space. Quote Link to comment Share on other sites More sharing options...
NickTheBassHeadCook Posted February 19, 2012 Author Report Share Posted February 19, 2012 What about 12s? Quote Link to comment Share on other sites More sharing options...
Decaf Posted February 19, 2012 Report Share Posted February 19, 2012 12s would be easy to fit if you can find 2 15s that work in 3-3.5cuft per sub as mentioned above that would be better....maximizing cone area within the space you have Quote Link to comment Share on other sites More sharing options...
Joe X Posted February 19, 2012 Report Share Posted February 19, 2012 Those will fit easily, at about 2.3-2.5 each you probably could fit 3. Quote Link to comment Share on other sites More sharing options...
NickTheBassHeadCook Posted February 19, 2012 Author Report Share Posted February 19, 2012 I really want the AQs because they are cheap for the quality, I would prefer 15s, there's no way to make to 15s work? Max dimension I can go with is 28.5(depth) 44(width) 18(hight). What would be the best AQ hdc3s to throw in that box? Quote Link to comment Share on other sites More sharing options...
NickTheBassHeadCook Posted February 19, 2012 Author Report Share Posted February 19, 2012 Also, the box for my l515s is 9.25 cubes after all displacements, I can post a pic Quote Link to comment Share on other sites More sharing options...
StrongmanDesigns Posted February 19, 2012 Report Share Posted February 19, 2012 You can fit the aq's and make them sound great if the box design is done right. Quote Link to comment Share on other sites More sharing options...
NickTheBassHeadCook Posted February 19, 2012 Author Report Share Posted February 19, 2012 You can fit the aq's and make them sound great if the box design is done right. You know anyone that could give me a design for the 2 15s? I'll send the exact demensions, it should be right around what I posted. I'll go check exactly.
