Its for old dudes-- you can rock out -- then lay it flat and take a nap on it
whats a Kemper Klone speaker?
does it change into other brands of speakers????
Are there details of the build somewhere that I missed?



That isn't a TRM cab is it? Looks just like his.
ya'll have fun with that --- ive solved the problem by running all my guitar heads through a vintage 12" Peavey speaker.....Im good--It does change into other speakers! There are speaker IR's you use with the Kemper and these speakers are made to emulate other speakers!
So not only can you emulate the amp you can do the same with the speakers!
How did you know they were Polk?may I learn more of the Polk Audio speakers those look luscious ?
