Last time i checked, I think a 1200mm x 2400mm x 25mm sheet was around $70 or $80 at hardware house but i cant but sure of that because their website is currently under construction.
New Box Dimensions!
What do you gusy think of the following internal dimensions for the speaker box.
Old Dimensions:
307 mm wide
469 mm high
200 mm deep
New Dimensions:
200 mm wide
552 mm high
260 mm deep
Post up your views of the new dimensions.

Re: New Box Dimensions!
Now you need to increase it enuff to take into account the volume of the back of the drivers, the cross-over, bracing, the port ... anything that is going to take up room in the cabinet.

How do i work all of that stuff out!?!?!?!?
BTW, do u know of any sites on the net that would offer a box design that would suit these speakers.
I read about one guys project on Parts Express and he said that he created a set of 2 way, floor standing speakers, but that if they were floor standing they would have too much of an internal volume so he split the box(internally) so that the top half was the correct box size, and the bottom half was filled with foam and carpet underlay.
Could I do this because otherwise i need to make some stands 4 the speaker and I think it would be easier and also look better using this method.What do u think??
Here is the site, take a look.

You could do that, and it would work fine and would probably be easier as internally you would have more room to move in. Personally, i would wait until you had a little more money for drivers, but if you wanna dive straight in, this is what i recommend.
Do as that site says, but split the floorstander using another piece of MDF, and make sure that it is airtight. Add maybe 20-30mm onto the length of your internal box that will hold your drivers and put the Xover in the bottom cabinet. Ports take up little room and the extra 20mm will cover them.
The bottom cabinet may also be filled with sand or something similar and the Xover in the top, its will ensure that it is stable and will reduce some resonances.

If I waited until I had a little more money for drivers, how much is a little more and what drivers would you recommend?

G'day Jeroth. The speakers you've linked to looks like a pretty decent project. I'd be inclined to take griff's advice and save up a few more dollars and build a pair of those.
Re: ????
It is just a math problem. Your box is simple enuff that bracing could probably be limited to some edge on hardwood boards (ie 20x40mm). These should go along the walls in there long direction such that the divide the panels into 2 unequal trapezoids.
This is not that uncommon -- filling the bottom cavity with something like dry sand would be better than foam & carpet.

Hi All !!!
I don't visit here often enough obviously !!!
A couple of things though,
1. Check the response curves of that HP170Z2. It has a huge peak at about 3.6k. You WILL NOT be able to use a series cross-over with it. I would suggest a 2nd order or higher parallel with this driver, which one of the other guys can help you with.
2. On the comments re hockey earlier in the thread. Perhaps I should say the Australia are right up near the top of the world rankings in both mens and womens hockey, usually in the final 2 or 3 at the Olympics.
have fun, looks like you are hooked !!!

OK. you guys must be talking field hockey & not ice hockey.
I wonder how many different games are called foorball?

Enough of this sport talk (yeah i meant field not ice, ice is tiny in Aus).
Andy, can you please sim this guy an X-O, lets get this ball rolling.

I repeat. This woofer CANNOT be used for a series x-o. I would not even attempt it myself !!!!
It requires a steep slope parallel, maybe even a 4th order LR to avaoid that large peak in the response.
Sorry I can't help, but I deal specifically with low order series x-os..
If you go to http://www.globalnode.com/users/stevenr/spkrs/
this will calculate textbook values for you, but really you need someone who can run the sims for you from curves and get values that will work properly in a real situation.
Good Luck !!

Just a thought ...... Jeroth....
Contact Peter at ME... peter@me-au.com
and ask if he has any AT170GO's left, this is a great driver, will work in a 16L box, and is good for series x-os. doesn't have that yucky peak !!!
have fun !!
say hi to him for me !!
