I have an old metal grill Mesa 4X12 cabinet with C90s in the top and 300 watt EVs in the bottom. I'm not sure of the difference between the old and new EVs though.
Heavy is a good word, that cabinet weighs as much as a small car even with only two! I use them with my Mark IV and I do like them. As others have said, they are very clear, neutral and I'll add detailed speakers. You definitely hear every single note. And of course LOUD!
I'd say they are bright, but that is probably and aspect of the amp and I feel like I can dial them how I want. I'll also add versatile because, due to their nature and depending on your amp, pick ups, etc., you can really play any style of music with them.
If you want a speaker that has sizzle, character, break up, imparts its own voice etc., probably not for you. If you want a speaker that is neutral, detailed, versatile and loud as f***, then you may want to check them out.
