hi

I understand because of the nature of open baffles that the bass besides the panel/open-baffles so between the OB speakers is close to zero?
If this is right
then placing my audio rack exactly between my speakers will give them the best protection against unwanted feed back loops and vibrations. This advantage when true, is not subliminal, no?

For the same effect, non OB speaker owners have to spend an extra hundreds or even thousands of dollars for good damping devices?

I am far from an expert on how rooms and sound interract, but I think this summary might be a little too simple.

Sure, the null of bass from a perfectly flat OB (no wings that are not parallel to the main baffle) is directly to either side of the baffle, BUT I am sure that with reflections coming off both faces of the baffle, that there are plenty of waves hitting anything directly between the baffles - not direct sound from the drivers, but reflected sound.

So too with a conventional speaker - there is not much direct sound coming off the sides and back of the speaker, but plenty reflecting around the room.

Were I concerned about airborne vibration, I would try what you suggest, but I would also seek to keep the rack as low as possible.

Just me,

i was under the impression if you measure bass in between OB speakers you would measure considerably less bass compared to non OB designs. Not zero because of the reasons you mentioned but (much) less
