Gorgeous system, the room and the cabinet/stand woodwork is beautiful ... as long as you have the leading edge of the center channel speaker protruding just a little from the cabinet enclosure you should be fine with the sound, it's whenever the speaker is tucked back into an enclosed shelf where the sound may be compromised. It does look as though your 150 is protruding from the front edge of the enclosure?

Great job.
