Well, it looks like you've somehow managed to just drop this "oops" box of yours in there and very neatly offset some main speaker small peaks and valleys, which is VERY interesting, if not the point... 

Not really, the response of Macondo itself and the Injected Macondo are virtually identical. Be advised that that way how I listen my playback the injection channel even 3dB less then at the graph above.

But my guess is that you would have to go way over to the dark side to get anything significant from the Red below 100Hz, ie, the "B" word (boost), IF more "oops" LF is desirable.

I do not know, and I do not think you know. However, I know how 1o” Reds sound in 1.5 cub feet and in 6 cub feet (I have both), so I know what I will get.

My own experiments with BR port variations indicate that a LOT depends on the box itself, no surprise there.  If less-than-rock-stable, the skin itself tends to resonate, as everyone knows, but the surprise for me came when my "crappy box" resonances went up and down in pitch, complexity and volume just with port tuning.  I started with the typical rookie bid to get all LF I could, and just at or below the point of lost reason the cabinet sounds just took off, and they got very "interesting", even though this was not what I was after at the time.  I was using a 15" concentric, I don't remember which one right now, but I started off trying to A/B it with my VOTTs and wound up running everything at once, much to my wife's consternation.  Room modes were HUGE in my case, in fact that's mostly why I gave up. Oddly enough, however, the "injection" changed and/or smoothed out some primary LF modes, and it was "up the scale" that I ran into more serious problems.  I only had so much latitude with room treatment at the time.

Pail, it all might be OK for a normal operation but it is absolutely not applicable for Injection Chanel. You think that the Injection Chanel should have some kind of balanced sound but it is mistake. The Injection Chanel is a lemon - it added some taste and flavor to the whole salad but it is not meant to be eaten itself.

Anyway, since this thread is already "toxic" I will stop beating around the bush and just toss it out there:  Equalizer... I add as I run for cover:  Narrow Band Equalizer...

Perhaps, but I do not see need to use it at this point. Also, not with the dual concentric the Injection Chanel is in phase across the whole range. How it will be after EQ… go figure. Anyhow, I do not know what which purpose I would use EQ…
