I just emailed Danny at GR-Research, and will probably order through him. I just wanted to see if there were other opinions out there.
Back in 2007, I bought a whole set of X-MTM, X-SLS, and X-CS for a 5.1 system (along with HSU research subwoofer, which conveniently was located in Orange County where I live :] ).
I just noticed that the high end frequencies aren't playing from one of my X-MTMs which leads me to believe just the tweeter is bad. I switched the speaker out with an X-SLS and it played just fine along all frequencies.
Is the tweeter just a standard 1" that I can switch out, or do I have to buy a tweeter directly from Danny?
I couldn't really find any markings on the tweeter, so I'm not really sure.
Here's a link of my X-MTM and the tweeter in question:
