Hey sic and Gil I don't see why you think I am asking too much. I really want to get into this stuff and see how many variables are wroth paying attention to. Like you were telling me that a well built box will sound amazing yet you are saying I should build my own box(which I want to) yet I am probably not going to get a great box the first time or am I wrong. I have noticed some ported enclosures on the inside look like a rat maze, whats up with that? Why have a bigger box tuned to the same frequency as a smaller box for the same woofer ? You said for my cobalt I had to make a smaller box since the trunk space was limited.So say the trunk space was bigger what is the advantage if the speakers and tuning stay the same?

larger boxes hit lower easier than a small box so to do a small box you need a sub that is meant for a small box ;)

what I mean about asking too much is the technical stuff that will take years to learn from experience not just reading...and you have so many misconseptions about it that you can't see what is what at this point...just get decent entry level sub and amp and build the box to the specs i will do for free and u cant screw up...

Here is what I think you mean. You can tune any size enclosure to any frequency but bigger boxes will play the lower frequencies louder is this correct?

not necessarily louder just more easily.. but the larger the box gets the lower the power is that the sub can handle.. it is based entirely on what the sub can and cannot do.... the box it is in is everything but HAS to be made according to the sub...that is why prefab boxes are junk...

my box designs are so simple a caveman can do it.....i do them with labeled cutsheets so all you do is cut the pieces and assemble it with glue and 1-5/8" screws ;)

Is it easy to build a box if you follow instructions or will it be trial and error?
Its not so much that. Long story short- I wont attempt to build a sealed box without the use of a table saw to cut pieces. The importance of the entire width of the cut pieces to make perfect joints is too critical to leave in the hands of a skill saw.

What about a ported box?

@Yngwie:
I use a straight edge and c-clamps on mine for a clean cut.
Either which way, it is a route to near-perfection, or results are not satisfactory.
And supposed 'good ideas' like symmetrical sub placement can weaken the baffle board. Lots of little things to look out for. In a small enclosure for example the baffle board is weakened significantly by the hole for a speaker, and on larger boards the length of the board itself makes it shaky. That leads to the "hamster maze" of bracing which holds everything closer to spec. Which in turn consumes airspace, requiring you to know WHAT you are building before you build it, so that you can compensate, as .1 cu ft of bracing makes a HUGE diff in qtc on say a 1.2 cuft enclosure.

Are you referring to why some enclosures have a maze like pattern and some just have a single line and stuff? What is the point of that?

no, we are saying he is a troll he doesnt have a 7500 watt amp... orrion HCCA subs will take upto 4-5kw daily...4000-5000 rms...
maybe he meant 750 watts or he has one of those way over rated ones and doesn't know any different. you guys are too harsh on some of us noobs lol. i had a Pyramid EQ amp that said 2000 watts on top of it in big letters back in HS. wish i still had it for the humor but i noticed the cheapest stuff always seemed to be the flashiest with the baddest names or high numbers. buyers don't care to learn anything, it goes boom so they keep buying them i guess
i'd recommend the OP perhaps try a combo kit. Like an RF loaded enclosure with amp at BEstbuy. its affordable, simple and better than what he has. Most of the average joe's find them adequate it seems.

Yeah that is the maze I am talking about.
It's called a labyrinth port. It's used when the port area required for the tuning you want dictates a port larger than the box.

Are they hard to build?
