Yep, it looks weird, but the improvement in sound was really significant and well worth the effort. I listen in a low-light environment, so the mats on the speakers don’t bother me at all.
The surface area of Legacy Signature III's is about 2400 square inches (removing a reasonable allocation for the drivers). The PPT Mats are about 75 square inches (from tweakaudio website). That means that each speaker would require 32 of the mats to cover the speaker. 2 speakers would required 64 mats. At a price of $300 for the original, that is $19,200 in mats. Now I have no doubt if you bought 64 you would have gotten some discount, but I think most would question whether the best spent on the way to audio nirvana.
