Ok, but let's just keep it simple. We all know that different size cabinets and number of speakers sound different. For each their own. You don't like 4x12s and that is fine. Others think different.
But what I'm saying is, will the Kemper speaker really behave like a V30 (or whatever given speaker) in ANY of those formats? If they have really accomplished that, it would be remarkable. And I believe that's what they claim to have done.
Doh - I think I misunderstood you.
You mean changing your current speakers in your 4 x12 for the new Kemper/celestion ones ? Sorry I though you meant just run the new speaker "profiles" through your current cab.
In that case it will work BUT there is the unpredictability of the cabinet itself. CK said they would offer them for retro fit so interesting if the DSP will account for the config...
Sorry for the confusion, I'll shut up and sit at the back
