Can I plane the top and bottom of the speaker? You wouldn't see it anyway once its in the cabinet.
I would plane the entertainment center shelves before I planed the speaker. How much are the CM5 and 705? It seems they would be an upgrade from the LM1 and you can keep using your center speaker that works for you.
Found this by Googling:
Bowers & Wilkins’s new CM Series will be available in October and will be priced as follows:
CM9 $1,500 each
CM5 $750 each
CMC2 $1,250 each
ASW 10CM $1,500 each
Thing is I really want to upgrade the subwoofer as well. Not a big deal because I'll move the speakers I have to a condo that we have in mammoth where I have really cheap speakers now and then move those into our bedroom where we have none. I would suspect that equal B&W quality speakers & SW are going to be significantly more expensive.
