Should I place bass absorbers directly between the speakers?

Hi. 

I'm making a number of large, open-faced cuboid bass traps for a modular bass trap system in my studio. 

They are, of course, going in all the corners, behind the speakers and on the facing walls. 

My question is should I put them directly IN BETWEEN the speakers? (Stacked floor to ceiling so the speakers can't 'see' each other)

(Please see attached sketch) 

I haven't seen this done  before and wondered if there was a particular reason why (other than space/aesthetic)?

I had assumed, given the omnidirectional nature of bass, this could be one more area where it'd be good to soak up some energy. But maybe not?

Any advice would be very gratefully taken!

Many thanks
