Hey everyone, I picked up these sexy red PH112 a few weeks ago to start replacing my old,heavy gear and find something to compliment my new Mesa D800. Playing them at home sounded great, in a band setting I found I was farting out(probably my fault). Took off the grills to check out the state of the speakers and found what look like two different drivers in them. They sound pretty similar but was mostly wondering if anyone knows which would have been stock or if they're just different builds? The back of the drivers both look the same. Thanks!
