Bumping for recent experiences. I have Creamback H/M mixed in a diagonal 2x12; top panel open on the back of the cab to let it breathe a bit.
I play modded marshall amps, which can be a bit bright. Maybe the Celestions aren't broken in yet, but they tend to get bit to 'gritty' or piercing at higher volume and gain, and I find myself running my treble at zero almost.
I like my amps to do the EQ's and adding cut and distortion more than the speaker, but some speaker flavor is good. I play hard rock and some early metal in a cover band. Zep, GNR, Kravitz, AIC, Tool, Black Album Metallica.
I have a Redback and J75-100. Each I tried in a 1x12 with ported vent in the back and I much prefer the J75 as it allows me to use my amps EQ more and it still cuts, but the Redback is an awesome speaker for sure! ...the J75 I have is a 2011 and I guess has Weber parts? I dunno, it just has a sticker that says Weber...
Anywho, Scumback speakers for rock/metal?
