I measure center-of-bubble to center-of-bubble b/c the receiving function is the more critical function in this case.
That makes you close to 27" & a primary factor I believe.

It's around 26 1/4" on the front and 23 1/2 on the back. The bubble is inboard on the front and outboard on the rear. Does it matter how they are oriented? Thanks.
Thanks for your help and advice Tom.
