12" diameter x 11" depth tubes on the back, effectively u-frame baffles I think to help with bass response with the woofers.

Very best,
 
Ok, not a pic, but all the open baffle experts are in here.

I'm looking to change up my design from 6*9" wideband for mid/high, 12" midbass and 18" woofer.

I'm just doing this to experiment. Love what I have now but kind of need to try my other driver choices and see what I find.
Mundorf d25
5" ems ma5ex field coil
12" field coil midbass
And I would like to look at a different bass setup. I was thinking of maybe 2x12" per side.

Really, I'm looking for any and all suggestions because I'm kind of going in circles. I considered servo, ripole, but really I would like it to be all one speaker, and maybe try to be less wide than the 18" demands, hence considering dual 12".

Love to hear your thoughts.
 
Why would one want to use waveguides on the back and not on the front. Those recesses at the back do act as pretty bad waveguides. I have made that mistake once, learned my lesson and will never do it again. It measured and sounded pretty horrible compared to a thinner flat baffle
This is my last shape with linear results and real punch bass. Its 73 cm wide, with side wings of 30cm. Next days comes the Lii Audio w15 and i will try more narrow. I prefer 8mm pine wood reinforced with strips.
I would like to have all the drivers on one line and am thinking about slanting the sides next to the midrange and treble. But I've noticed so far that any changes away from a simple straight plate no longer make the whole thing sound homogeneous. I see you have a lot of experience, so I would be particularly interested in which shape is your favorite.
