Umm, yeah, subscribed! :hsd: I'm looking forward to seeing how this progresses. You will get expert advice here...just not from me on design with WinISD.

When i came home after work this was waiting for me:
Here are the T/S parameters as provided by the manufacturer.
Now i need to spend some time with WinISD alpha 0.7 and then try my hand on sketchup.

Now i need to spend some time with WinISD alpha 0.7 and then try my hand on sketchup.
Here is what i came up with:
about 400 l net internal volume
My sketchup skills are not the best, so the drawings do not include all the details.
There will be 4 triangular ports, 2 each in diagonally opposed corners. To get to the necessary length, they will run full height and part of the side of each side panel, thus providing substantial bracing in all corners.
The top and bottom baffles are rotated 90 ° to each other so that the ports construction stay clear of each other.
The 5*5cm braces under the top and bottom baffles should eliminate the need for a double baffle, as well as provided sufficient meat for the T-nuts.
They will also provide more breathing room for the drivers and allow for a lighter construction ( i will have to carry 4 of them to the 3rd floor and i estimate them to be close to 200 lbs each, without the drivers:coocoo
.
Depending on necessity, i might add one crossbrace at half height of the speaker.
I will also put a 5 cm high section of 25 mm MDF between the ports at 25 mm below top , respectively bottom edge.
This will give me more surface for gluing the baffles, or give me the possibilty to screw the baffles in (this would actually be my 1st choice, rather than gluing, with the option of easy access inside the box or just switching the baffles if i needed or wanted to).
I did not represent any feet to the sketches, but i will have them about 15 cm off the ground, if i will use them in vertical position as drawn.
I will also buy a 2*8 MiniDSP and my brother will provide me temporarily with 2 Emotiva XPA 5 for testing purposes. 2 more heavy items to carry up 3 floors. I wish i was in the States with lower real estate prices and the possibility to have a basement theater.
Behringer websites says Nu 4-6000 now shipping, maybe that's what i will be shooting for (and a couple of silent fans of course).
My brother's 4 Atlas in a 500l LLT is currently in the process of testing. So far it is only running on 2 of 4 channels of 1 Emotiva XPA 5 and there are reports of substantial output already. Luckily he lives close to the airport so he can blame some ULF rumble on the aircrafts ;-))

On friday, i got my 24mm Birch MPX precut from the carpenter.
16 side panels 130*65 cm, 8 square panels for tops and bottoms and 16 130 cm long port boards cut at 45° on both sides.
Before starting the build, i slightly modified the plans. I will have no ports on top, but all 4 ports will exit through the bottom. I will extend the port boards 15 cm outside of the baffle, thus creating 4 feet that will keep the bottom subwoofer 15 cm clear off the ground.
Today i routered the openings for the subs in the tops and bottoms, then i started assembly of the first box.
First 2 sides glued and first port board in place:
3rd side glued, as well as 2nd port fitted (view from bottom end):
Top end view, 4 sides glued, 3 ports fitted:
You can also recognize additional bracing fitted between the ports.
The bracing is 25 mm from the top edge ( idem on the bottom part of the sub), allowing for a removable top and bottom. I plan to use a foam gasket on top of that bracing and screwing the top and bottoms into the bracing, giving me easy access to the interior of the box.
The top with the mounting hole for the sub is not glued, just fitted in to make sure the box stays true until the glue is set.
A couple clamps and tie downs make sure everything stays put overnight.
That's it for today, no more clamps available.
I still need to cut more braces and glue the 4th port board in.
I hope to find some time tomorrow or on tuesday for that, the next baffle will have to wait until the weekend.
After Easter i should have 4 fridge sized and very heavy subs. Already at this uncompleted stage the enclosures are really heavy. I had a hard time flipping the enclosure over to glue the 3rd port in:gulp:.

Lot of progress here! I wish I had even half the number of clamps you have
I fit the 4th port and finished the bracing on the first enclosure after work tonight.
Due to bad weather (ice rain and a little bit of snow) i skipped my badminton practice , so i got a lot more work done than originally planned.
I borrowed 4 50" clamps from my neighbour and i managed to get the second enclosure to the same stage that i left the first one last night.
I took some more pics that i will post later this week.
I stood the first enclosure upright on its feet and that thing is huge:doh:.145 cm tall, with the finished feet it will stand over 5 feet and easily big enough to fit an adult person.
4 of these will take up a lot of real estate in my homecinema.
2 might have been enough, but the sale was too good not to go completely overboard:rofl2:.
I should have enough headroom once these behemoths will be finished. In a worst case scenario, i could always put more power into them:innocent:, as a single Inuke 6000 will not overpower them for sure.
