I hadn’t even considered this.
Without the Kone speaker, the imprints won’t sound right. The Kone and imprints are specifically designed for each other.
Using other speakers might give decent results, but definitely not what was ever intended.
Most of the profiles I use are profiled with a V30, or just sound great through a V30 loaded cab...I bought the Kemper cab (..has the Kone..what else would it have??) thinking I wanted all of these different speaker type options, but nope, I like 1 or 2 maybe, so I don't need it. I hear it sounding pretty good for different types of cleans, but for the modern hi-gain stuff, either one of my V30 cabs already sound great (..of course I turn the "Cab" sim button off to monitor.) Again, the profuiles I use are profiled with V-30 or OS Recto V30 cab, so for when I need to be loud and have the air moving, I just plug my Powerhead into one of those cabs, still use the main outs for PA or recording. The Kone/cab just isn't for me. Love the Powerhead tho : )
