One more question, since I've never built any of these before, what would you guys suggest for wood? MDF? Ply? I know we're playing with resonances and wavelengths here, I don't wanna fry the whole idea by using something wrong!

Hi, Use good quality 3/4" PLY and cross-brace :
PS: If the extra volume of the cross bracing is added to the enclosure, the volume saving holes can be omitted:

One more question! I've started to play with some of this exported data in Hornresp, and using some information I've gathered from some posts in the hornresp thread, I think I've got the data exported properly, however it appears that the "width" decreases, which I expect, but it looks to me as though it's decreasing in both directions, which means the cabinet gets thinner as well?

I'm sorry about noob questions but this is my first try and I want to do it as properly as I can!

Does this look sorta how it should?

The measurements aren't right yet, I just kinda drew this freehand, but I want to make sure I'm on the right track!

Bjorno, my exported horn data has got to be incorrect. I've been reading tutorials all morning and I can't seem to come up with good measurements to use so that I can model this thing to the right scale.

Hi,

I'm very busy for the moment... but I made a quick drawing that may help a bit..

b

PS:I haven't used the exported HR data yet, Round off (up) my given dimension numbers to 1/8" ...I'll be back later...if you have more questions.

Haha! Thank you very much! I was off by quite a bit, here is what I came up with this morning. I'll make another model with these new dimensions if you want to check it out later.
