Is there one? If not, what Eminence would be good for progressive rock, sometimes venturing into metal?
I hate speaker buying. It's like buying a pickup. You never know exactly how it'll sound until you buy it and install it.
...probably a Legend series (1258), or maybe a Texas Heat out of the Patriot series? You're going to look for something higher in wattage with a tight low end, strong but not-too-peaky midrange and plenty of brightness.
Maybe the Screaming Eagle. I don't think that the Redcoat series is what you want - that's the "British" flavor.
