GM-
Could you point me to the thread in question? I realize that speaks are a mix of art, science, and personal preferance. I would like to read over the discussion to see which is which.
I wasn't following the subject when all this was discussed, so I am , once again, clueless 😉

I'm referring to earlier in this thread when the conclusion was better to have too much and attenuate rather than potentially being caught short.......... Remember, cutting gain always AFAIK reduces distortion and boosting normally increases it.

Ahh...that was my conclusion, but I didn't exactly get any confirmation...till now that is😉.

Oh really?! I thought I was in clear agreement here, but then English being what it is, we're divided by a common language 🙁: http://www.diyaudio.com/forums/showthread.php?postid=1144595#post1144595

And so you were..my apologies
. The thread was moving kinda quick at that point, and I was doing several different things at the same time (threads, email, Mathcad, etc.). The piece I locked onto was the felt gasket bit...I really need to pay better attention.
The point of my last couple of post's was trying feebly to make a determination of just how much bass I potentially need to cut. I was starting to get the impression that I would need to slice 10-12dB right out of the gate, and if that were the case, I would be better served starting from scratch (again) rather than slapping that big of a band aid on an "inappropriate" design. A few dB here or there fine, any new design could require that.
I rattled off my last posts in seconds as I was heading out the door to go home, and I really wasn't as clear as I should have been...I also really need to slow down. The confusion came when people I have grown to respect from reading a great many of both of their posts, here and on other forums (Dave & Ed) , seemed...I need to say that again..seemed to be suggesting one thing (cutting the bass response), while holding up examples of another (Ed's ML-TQWTL graph, and Dave's back loaded horns graphs his site hosts...though his sub's graph supports the cut). My assumption was that I was/am misunderstanding the suggestion. My gut tells me I was not grasping at which point the cut potentially needs to start.
Hope that clears that up 😉.

See, that's the thing, unless you measure the room's response you don't have a clue beyond some Simple Simon average. That said, you do live in a locale where the tool sheds are better built than a typical Deep South home, so at least your corners should load close to theory down to at least 30 Hz, so if you plan to put them in corners, then a response ~like the sub's should be close, though even then I'd start with more gain and dial it back if need be.
If they will be out well away from the walls in a fairly large and/or open format and/or well damped room with plush furniture, carpeting, then you'll want all the gain you can muster.

I'm afraid I have to agree. My room doesn't fit neatly in the small or large category. Oh it's smallish...with one wall missing 5 1/2 feet as on opening to the dining/kitchen area, which in turn has an opening to the utility area. So in terms of placement, they have to get closer to the back wall than I like, and in terms of volume, I'm pushing a lot of air.
I'm through with my neurosis, and I'm just gonna build the damn things as designed, I can always peel back, or eq the lower bass if needed. The only thing I'm going to do differently, is to make a removable baffle set up so I can play with different driver placement. My ultimate goal, as I mentioned in the beginning of this thread, is to have a long dipole ribbon on the side. That however is a ways down the road, in the meantime it will have be a little more conventional.
