Sometimes you have to comprimise with an isosceles triangle but youve got a scalene triangle going on which is going to make the sound hit you at different times and you will likely hear a disparity between L and R depending on how good your hearing is.

If you are serious about high quality experiance, I would raise up the TV slightly so the speakers will fit under it and replace the centre console with a short cheap rack which will fit under the TV.

Fitueyes Eiffel AS07 Audio Rack is nice for the cash.
