Excellent comments from all of you once again.
Here's my responses (so far) and thanks for the good advice :
Thanks again for the kind words of encouragement.
BTW, I'd seen a lot of OB designs that that either integrate an H Frame stacked or not stacked Woofer cabinet below the OB Panel so my panel was tall enough (barely) to accommodate. The difference is I have no top brace/shelf in my design.
I also saw a Video with Clayton Shaw (Spatial) who suggests the upper Woofer be crossed over higher while the bottom one is X'd at 90Hz.
Baby steps but I can hear the potential.
Here's my responses (so far) and thanks for the good advice :
- The side wing (a la NX-Otica's - Danny Richie - I watch his Video's too) idea is one I will try 1st and foremost. Makes sense and he gives an excellent explanation why as you mention too. It's the center focus problem. I have enough material that I can temporarily make a side wall on top of the 1.5" thick side panels of the H-Frame Woofers.
- Build a box around just the Midwoofers leaving just the 12" Woofers and the Tweeters Dipole. Changing the crossover points from 250Hz - 2500Hz to 120Hz - 2500Hz won't be hard. I have lots of Inductors laying around that I can cobble something together. Lowering the 12" Woofers LPF to 120Hz is a snap with miniDSP.
- Placement currently is 5ft. exactly from the "front" (TV) wall to the back of the H-Frame Subs (5', 9" to the Midbass/Tweeter Baffle). Right side is only 2.5ft. from the room's side wall and the left side is a whopping 7", 4" from the entrance/side pocket opening/WINDOW (I have to draw it out for you Guys), Also on the right side the Speaker face a Hallway. Also the swinging doors to the kitchen are wood in a glass frame window embedded. I'll take some pics and a floor plan with room dimensions.
- Toe-in on most box Speakers friends have lent me gives me a great center phantom image when placed straight out into a room except for a pair of KEF R3's that worked best with about 10deg of toe-in.
Thanks again for the kind words of encouragement.
