Hey,

Im making a subbox for my year 12 assignment Design and tech.... i had been told it is an easy project todo but also technical, ive been looking for plans of a sub-box to give me ideas ive seen pictures tech, but i want a couple of actual plans that can help me.... and also the teacher had said that a sub box isnt just a box with a sub in it sealed up .... its more like what size of the sub and type so that the measurements of inside the box are right for the bounce of the sound waves....

Please help

your teacher is right, the box needs to be a certain amount of volume so that the sub sounds good and u can get the best performance out of it, this depends on the sub - the size and power of it. it is best to consult the specs of that certain sub, it will say best volume etc.

Trying to make a 2 x 12'' Sub Box, i got two 12'' subs BOSS 800w but i cant find nothing on it on the net.... i can find on the sony website about the box but not these brands....

i did the exact thing for year 12 last year. i made a fibreglass box. it is quit simple to do. if you need any questions just add me on msn sjoseph87@hotmail.com

Yep, what he ^^^^ said.

Here is another site to consider as well. It has a in depth box building calculator and explanation with many US / CDN retail and industry members.

I know DD Audio website has box specs + formula's for calculating ports, example designs etc if thats any help also

Find out what type of sub you are making the box for first, then we can give you the best suited box

Thanks,

I have actually got 2x 12'' BOSS 600watts each....

Well there lies your problem - Boss isn't a very reputable brand and therefore doesn't supply stats like RMS figures for power nor recommended enclosure sizes.

To determine what size boxes you need, you need the thiele-small specs (also known as TS specs). These include information abbreviated by things such as Qts (Total Q Factor), Qes (Electrical Q Factor), Qms (Mechancial Q factor), Vas (Equivalent volume) etc - using the figures in the TS specs you can plug those into an Enclosure calculator (something like WinISD - it's free, Google it) and it'll recommend you what type of enclosure would be most suitable.

However as I mentioned about Boss not being very reputable, I don't know whether they'd supply you with the TS specs when you purchased them.

To help with the assignment though, being design and tech, I'd assume you'd need a brief with it relating to what everything means. I'd thus recommend searching Google and giving a brief description as to what TS spec means (ie. What Qts stands for, and means). When I did an assignment a few years ago relating to the Physics of sound I believe I came across a website which had all the definitions of TS specs in one spot.

Hope it all helps!
