I think the 2d element is the most important because it is the one most likely to be comprimised. Firstly, it can't enjoy any of the advanced variations that a 1D can, so no depth saving. Secondly, the well width is likely to be made larger than optimal to let you fit your insert, so the 1D bandwidth may not be all that great.
Plus not to mention, a great part of doing this is for the cool looks!
trouble is, tho the walls I feel would give better results, they won't look half as cool as the skywalker ones.
Still, walls it is.
I would probably do N7's for both. Also, I would use the normal panel for the 2D, rather than the inverse - save's just that bit 'o depth.
Well, I agree with you that the 2d element is the most important, so I think it would be a shame to go only a 2d seven prime myself. It also leads to a wider well, which means a deeper insert to match/cross frequencies.
How deep can the finished panel be?
Ultimately it does not matter, but with the design you gave later I don't see the need for it to diffuse that low. Somewhere earlier in the thread I posted a link that talked about the 'realistic Flow' being 400 hz. that seems to have stuck in me 'ead so have always thought along those lines.
that equates to a depth of 195mm, that is fine to me.
So I will stick to the 1200 dimension for various reasons, not least being I can use it elsewhere later!, and will go with an eleven prime (hey, if I'm gonna do it, then DO it, so no pissy little prime sevens for me hahaa). thirteen get's too big etc etc, so a nice compromise.
2D prime eleven, design frequency 800, width of well 106 (3mm walls)
insert prime seven, design frequency of 3244, depth 31, so add that to the 2d and total depth is, well whatever it is.
that insert give me two red crosses, 105 panel width vs 108 design width...can live with that, and well width under 25mm, again can live with that.
Unless you can see serious problems with that, the Tercolpo is set to go.
