I think he means, and is right too,
that if you make the top & bottom at correct size,
you can use them for to make the other sides fit.
To get the correct sizes, so everything can go together.

Just what I can figure out.

Ahh, okay, thanx halo..

This is basically how I want to make the speakers, 1 pixel=1mm or there abouts, the tweeter is actually too big I think..

Should I put bracing between the woofer and tweeter? It seems like a good idea to me..

Yes. Sorry I was lazy to write this morning. Doing that ensure that your sides are 90 degres (unless your top-botton aren't). Never glue a whole box at the same time. It takes few days to glue an entire box because you have to do it in several steps.

Bracing between the woofer and the tweeter are good if you have space. The space between the woofer and the tweeter is not random by the way. I suggest you the as closest as possible and do some listening test. You can make two or three baffle before finding the right one. This is why you should never glue the baffle until the end. You can use scew or clamp temporary.

See, I have a problem with that, cos I am making these at school, I have no amp, and don't wanna waste my money on baffles..

lol I knew that it was best to have the woofer and tweeter as close together as possible..

You say the space between the woofer and tweeter isn't random, but you say to make it as small as possible.. does this mean there is an optimum distance that connot be calculated, but rather has to be found by trial an error?

SkinnyBoy · 22nd January 2003, 01:55 PM

I get my speakers tomorow..

hehehehehehe... first, I break them in... how..

Man, this is a learning experience..

What frequency, how loud? Also, do I need to break in the tweeters?? I think there should be a speaker box making guide for dummies.. with ALL these answers in it... I might do that some time..

will enable to to organise all this info as well..

The ideal distance between the centres of the tweeter is usually considered to be related to the crossover frequency (which kind of makes sense when you think about it). I can't remember the recommended ratio, but half a wavelength at the crossover frequency rings a bell (although that does seem pretty small to me). I'm sure somebody slightly less sketchy than myself will be able to offer a slightly more useful and infinitely more informative opinion ......

Put the tweeter as close as possible to the woofer and it should be fine. Calculation are complex and sometime useless since there is other factors that are more important.

I break my drivers with radio music for 100 hours.

SkinnyBoy · 23rd January 2003, 12:49 AM

Okay, no calculations..

Put them as close as possible, probably so I can just fit a brace between the woofer and tweeter..

I don't want skinny towers.. lol... they are too hard for me, the hole is too near the edges..

SkinnyBoy · 4th February 2003, 05:43 AM

Well, an update on the speakers.....

I CAN"T START MAKING THEM UNTIL SECOND SEMESTER.... Thats like 5months...

Also, I asked the teacher about it, adn he said that they normally don't allow students to make speaker boxes... Well, I am still going to make them, because these AREN"T that simple, they have bracing, and rebated speakers, and whatever those corners are called..

lol (What are they called? the ones where I make it so the sides interlock? I want to know what I am talking about when I go to the teaher next) Also, I asked about MDF thicker than 18mm, the teacher said they don't EVER get any thicker than that... Also, he reccomended I used 16mm for the WHOLE BOX!!! well, I am not doing that..

lol.... I figure I can always get my own MDF from somewhere... and bring it to school.. SOMEHOW!! lol
