Spendor SA300, soffit mount or not?

Hi all, I'm still at the construction stage of the outer leave of my studio, so I still have some time to decide how to mount my monitors. I have Spendor SA300's: http://mixguides.com/studiomonitors/Reviews/spendor-audio-monitors-898/

As you can see the sides are not flush with the front and that's the part that leaves me puzzling. I'd rather build a soffit in my CR, but I'm not sure if that's a wise thing to do with these speakers.... thanks, Coen

No direct experience with these or Adams (also with wierd cabinets) but found this thread, hope it's helpful - http://www.johnlsayers.com/phpBB2/viewt ... dam+soffit

Thanks Steve!!!
