Possible not but the intention was to go baffless, I bought them before deciding to go OB. In hinsight I probably gone with different drivers. There is nothing wrong with them just limited in this application.

If he doesn't do it. I will do it for you. It won't be much different.
How are you going to run your woofer in OB? H, U, Flat, PHL, W, Slot

Just EQ it flat to 200Hz. I don't think excursion will be a problem at 200Hz

I was playing with the idea of a single driver slot but have changed my mind on that.

A H box seems to make the most sense but I could also see myself doing something between a U and a flat. Some more of a \___/ with a brace from behind the driver to hold it steady.

Im not concerned about the excursion it just lacks oomph... If I turn off the 18" so it just rolls the 12MUs off at 300hz they sound tinny like trying to play bass through a portable transitor radio speaker from the 70's. It is fine up higher it just has no depth in the bass.

It may measure up ok and have SPL, but they have no real substance to the voices or bass down lower.

They are designed for sealed enclosure and I am using them for the exact opposite of that, no baffle at all.

That is because you have no baffle

Edit: I am not arguing with you just trying to help you see the options you have. Don't be to quick to judge them.

GPA416 is very nice in the vocals.
I know I am sounding like a broken record. Hahahahaha

This might seem like a weird idea but the SeasFA22RCZ would make a nice midrange. I have them and they are good in the bass and midrange.

EDIT: Lots of flexibility with the crossover points

If I was planning on running them in a baffle I would consider using them lower, as I would get some dB reinforcement from the baffle, but I am taking a leaf out of StigEriks book and planning to run them baffless.

I have no problems with running a separate mid woofer as I already have a 4 way active xover so nothing stop me going 4 way and separate .1 channel for subs.

That is what I envisage using for a mid-woofer something like that... There are lots of decent options in the 8-10" range I just need to sort through them and find something that is OB friendly.

That driver drops off about 6 dB between 100 and a 1000hz so would need something a lot flatter through that range.

Looking for something fairly flat and about 93-95db
