timc31610 Posted May 30, 2014 Report Share Posted May 30, 2014 This is what we were trying to build the box off of. This shows 2 port pieces, the pic of your box has 1. Where is the other?

Guest Posted May 30, 2014 Report Share Posted May 30, 2014 even if the box is an acceptable size, that port is all wrong. Link to comment Share on other sites More sharing options...
poorfish88 Posted May 30, 2014 Report Share Posted May 30, 2014 I should have let my builder do the design and get the wood cut ended up spending $90 on MDF trying to get it the design right and we still might have to put blocking in it to get the correct cubes. He told me anytime he does DC builds, it's always harder than it has to be. Why is harder to understand don't put DC subs in box too big. Bro your builder can't cut the wood? Your builder just went from legit, to really he's just your friend, right? Link to comment Share on other sites More sharing options...

ChevyBoy95 Posted May 30, 2014 Report Share Posted May 30, 2014 I think you'll find that most manufacturers "recommend" box sizes that are as small as possible as a marketing gimmick. It's far easier to sell a 15" woofer if you tell buyers that it'll work in 2-3 cube than if you tell them it'll want 5-7 cube to really get loud. Your average knuckle dragger that throws tons of money at this stuff wants as much cone area as possible, isn't willing to sacrifice space, and is easily impressed by inflated power handling claims. I'd wager few of the people saying "you'll break the sub" have ever actually ran a 15" woofer in 5 cube. Assuming your tuning is right, I'd guess that the box will be fine. You may be a little peaky around tuning (but not knowing the peaks and nulls of the vehicle this may or may not even be bad) and you'll gain some efficiency. Generally speaking 25% increase in box volume is not going to be particularly dramatic. Correct tunning, sufficient port area, and solid construction are far more important in my book. IMO if you're mechanically breaking a 15" woofer in a 5 cube box, you're being a total arsehole playing way below tuning or the sub isn't built properly. I'll go even farther and say that triple joints should be about the last thing to break if the sub is build properly with good quality parts and glues. You seem pretty seem ignorant. 5 cubes is huge to most 15s. That is 18 territory as far as box size. Some subs are designed to do well in different volumes as well. And these companies most of us use on here, their recommended box size is dead on to perform well at rated and most cases up to double rms power. You must not do any testing because there is a clear behavioral change depending on who makes the sub with relation to box size.

There marketing gimmik is making badass subs and amps. Hint hint triple joint gets tons of stress on big boy subs and boxes too big . Lets say the DC XL15 3cub box required at rms power. Now take the same sub and put in a 5 cube box and tell me the triple joints that last thing to break. May be the second or first depending on how many times the VC can hanldle being slammed into the back plate. Link to comment Share on other sites More sharing options...
