I thought about the magnets while I was planning the build but had the guides on hand so I went that way. The magnets under the veneer do make sense so next cabinets I'll give it a try.
Surprisingly, the PE grill cloth doesn't muffle the sound at all. I stood in front and removed and replaced the grill several times and heard no difference. Maybe at the listening position, tho'...
However, I had the backs of the cabinets just a few inches away from the fronts of the 4Pis until today and the sound was as if a wet towel was over the speakers. I was concerned, to say the least.
Today, I moved them to about 8" from the front wall with the 4s in front and the sound is clear from bottom to top. I absolutely love these giants for bass weight (maybe a bit overcooked at times), mid-range timbre and that very rare commodity, gorgeous massed violins.
