I have the KB500, a 15” speaker in the “kickback” configuration, so you can angle it back to hear it better. Best combo amp I’ve ever owned.
Agree with the Hartke choice! I own a Rumble 200c with the 210 ext cab. Sounds great. I also Own two Hartke HD 25 that I split a signal to both! I would go with the Hartke rig you’re thinking about. I love my Hartkes.
You have to define all three of those terms. You aren't going to get a five-pound cabinet that your drummer will be screaming at you to turn down for a hundred dollars. But, I got a 35-pound cabinet that my drummer has politely asked me to back off of, for $700. There are heavier, there are wimpier, and there are definitely more expensive. Trace Elliott, especially their older stuff, comes to mind as a brand that was thoroughly unimpressive and undeserving of the asking prices I was seeing. But, there are cheaper, louder and lighter. I've just never encountered anything that was all three compared to this CMD102P.
I myself maxed out light and loud with a pair of barefaced cabs. Each is below 20lbs and as a stack, when you really turn up the amp, you can't hear the drummer complaining. Or drumming, for that matter.
I have a Fender Rumble 500 v3 paired with 1 (or 2) Rumble v3 4x10s. Its not my top gun line (Mesa WD800) but its reasonably priced , has enough juice and sounds good when you take the time to get to know it.
