I am still stuck in the stone age and don't have a digital camera, but the outside dimensions are 16.5" X 20" and it is made with MDF. I attached a cutout sheet to give you a better idea of what it is like. Each side of the box has two braces running in the short dimension with two cross braces connecting opposite faces of the box. The cross braces are connected to the "rib" braces ~1/3 of the way from the side of the box, with the rear cross braces on opposite sides as what is shown in the figure below.

Construction tips: I cut all of the 16 1/2" dimensions a little large (usually ~1/2") and use a flush cut router bit to trim the edges square prior to rounding over the corners--5/8" for the face and back and 1/4" for the other edges. I use liquid nails for assembly because I heard somewhere it helps with dampening, although I have not personally done the experiments.

All inside joints are caulked to ensure no leaks. To finish the box, I just primed mine because it will not be in plain view, but if you want it painted to look nice, I would use bondo to fill any cracks where the MDF panels join. I am shocked at how well it works as a wood filler, and if applied properly, it seals the cut edge of the MDF fairly well.

Hope this helps!

Here is a picture of how the internal bracing works. The illustration is, of course, looking into the front end of the box. Reverse the sides of the braces for the rear set of cross braces.

One more thing I forgot to mention, The braces and inner front/back should be made of baltic birch plywood if you have it, but I was a slacker and used MDF. If you want to use a shelf brace like that in your first picture, that would work equally well, but I was saving wood when building mine.

Just some thoughts.

Hi
dfdye!
Thanks for the help! The partsexpress mail for me from Julie Johnson:
The estimate delivery charges for the 2/ 295-466 DAYTON RSS315HO-4 12" HIGH OUTPUT SUBWOOFER (weight 26 lbs each) are as follows:

UPS Worldwide Express (2-5 business days) $523.35 estimated shipping - estimated total w/ parts $731.35.


Guys the price of this shipping is great.This is a gold driver may be?
The sipping=4 or 6 drivers more. The Dayton HF cost 104$
I can`t believe
If any can help me with any offer for the cheapest shipping I can`t decline it.
I can wait for this shipping and 6 months,but I want only low price for this.

If any can help with the calculation of this bass-reflex:

An externally hosted image should be here but it was not working when we last tested it.

For DAYTON RSS315HF-4 12" HIGH FIDELITY SUBWOOFER
Will be great.I have two cabinets Sony S333.I make him the cabinets for the high`s and medium`s and I can dissipate more MDF for the subs.

Will be great if any can give a link for any dealers or online stores for the Dayton Speakers not too far away from me in Europe.

I have no idea about options for cheap shipping, but as far as the ported enclosure goes, the Dayton RS High Output is supposed to be better suited to ported enclosures. I am sure you can do a search to find more info, but the summary of what I know is that the sound quality is still very nice, the power handling is substantially higher, it is designed for ported enclosures while keeping most of the same design features of the HF.

I have not tried to design an enclosure for it since I wasn't interested in a ported sub, but you should give WinISD a look and take a shot at modeling it yourself if you are interested. I was quite impressed at how easy it was to get started, but I also have not yet looked at how it models ported boxes--they aren't really my cup of tea. Good luck!

Use USPS.

NOT UPS.

USPS.

United States Postal Service.

It will cost you 108$ to ship a 52 lbs package to Bulgaria with an insurance of 325$ (to cover both woofer cost + shipping cost).

If PartsExpress want to ship two boxes, it will be 60$ shipping per box.
