Hi Dan,
The OP requested posting a google sketchup model, and I haven't made the time investment yet. I did some 3D drafting and movies in ACAD in the early 1980s, but this was sufficiently cumbersome, and time consuming, that I just stayed with 2D drafting, it'll do just about anything I need. We have some applications that'll force me into 3D one of these days, but hopefully not too soon.
Love the Maxwell Render pictures, but to vote you have to be on facebook or twitter, so just another page in the continuing corporate hunt for names and numbers. It's remarkable though what's available for "free".
Thanks for the link.

One last thing you will LOVE, search google and youtube for Space Navigator. This is THE kick *** tool you need as a 3D CAD newbie.
its the right lenght, but what about the mounting depth for the subwoofers ? and is the blue area where it needs stuffing ? it's the right size but i can do a bi higher if it needs to be as i dont want the risk of port noise or not enough space for mounting the subs
I could make it bigger but there is <20mm clearance to the rear and the mouth opening is <200cm².
did you mean 200mm from the baffle to the peice underneath it ? could you email me the design on google sketchup because thats what i use 🙂 ?
Just thinking about these type of enclosures; if one were to leave the top off and just flip it upside down on the carpet you could probably get by for testing as long as you weighted it down sufficiently to prevent any leaks or rattles.
Lower yet now that I think about it. I think this will need stuffed for the additional length of the bottom section. Would imagine it will push you into the low 20Hz range. I'll send data to b and see if he has a comment.
LOL,
Hope you are kidding BP1, I don't have anything entered. I am considering buying the render plugin though.

Stuffing will be necessary for reasons other than LF tuning, the stuffing is also used to dampen the resonant modes that occur at the upper end of the range. What do you use for a crossover to filter the high frequencys from the subwoofer? It'll sound like shite if you don't use a filter. Really you should have filtering to remove content on both the high and low ends of the spectrum, filtering off the lows below tuning will help protect against bottoming the drivers.
no i run a pair off q acoustics 2020 of the denon, and i have a power amplifier (pa amplifier) which is 250 watts rms to each channel that i use for my subs, with passive crossovers
