TD, welcome. As Alan pointed out, the results would be significantly less impaired if the M22s are placed so as to extend slightly out from the bookshelf. It would seem that the trim piece doesn't create a total barrier. Place the M22 on a book or other object to raise it an inch or two so that it will clear the trim and can be slid forward to 1/2" or so in front.

Enjoy the music, not the equipment.
