Al - They look good in there and I'm sure sound good too! Glad they turned out to be a nice upgrade. Guys have been pretty stoked on the mid bass performance. For those of you that have the SX65-C, this is not a huge difference going on. I get a lot of calls form guys asking," should I sell my stuff?" and the answer is no man. The C's sound great. The M is just the evolution of product design. They retail for the same price, we just tweaked a few things.
And yea, I liked the black cones too. That was just a cosmetic thing tho.
