What if an enclosure is too big for the subs?

[bassman619]

Wait..everyone is sayin its the design not the builder..in my opinion its both..if the design was flawed the builder should have noticed before building the box..all u gotta do is some simple math with a calculator to find internal airspace.. take the dimensions subtract the wood thickness and multiply them together then divide by 1728 and you get internal airspace.. do the same to calculate volume of the port and subtract port volume from box volume and you get net internal volume ..dnt forget to subtract sub displacement

lmao, i just want to say, that i think i was pretty damn close to what the actual spec were for that enclosure. OP, maybe you should try car audio Q&A on facebook. there is a ton of idiots on there that would help you. I am guessing that your "guy" is the guy at lowes who runs the rip saw and you fucked up.

Cut hole bigger add 18's lol

Always measure 2,3,4,5 times then cut once lol

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.

I was about to say, I am continuously tearing surrounds in 5.8 gross tuned looooowwww lol to be fair though i am burping 4x the reccomended power.

I don't shop at lowes.

Trying to see if I can get my subs changed to 18s since they haven't even started them yet.

[Ektro]

HAHAHAHA

[Ektro]

Subs already shipped.

Ugh going to cost more to build a box then it would have to upgraded to 18s...
