I have this:
Hellatone 60L + Scumback Blackback H75 - 65watter. This mix CUTS! I play my 5153 50 watt through it in my Forte 3D S/V and it's the sound in my head for years. At my last show, 3 songs in, some dude came up to me between songs and asked, "What in HELL speakers do you have in that cab?" I told him and he said, "Dude, YOU are cuttin' through like I've never heard. And what the hell cab is that??" The smile on my face never left. My search for a 2x12 and speakers to match has ended.
I put the 60L on the bottom and the BH 75 on top. First, I think you need to get the H series Scum as they are just a bit louder than the M's; the M's sound fantastic from the clips I've heard, but Jim recommended with my setup that I go with an H.
