All these years I operated on the perception that the 'Program' ratings are when the amp/cab are fed music and assess how much spank you can get get while staying within the frequency specs, RMS are derived from sine waves within specific distortion %s, and peaks are peaks are peaks = hot transients.
"Peak MUSIC power" is a rating you don't see much anymore.
RMS rating will be the lowest #, peak about twice that, and program somewhere in between. The 410TX is a good cab
but at 8 ohms it doesn't bring the volume quite as well as the later 410TVX @ 4 ohms, by themselves.
Personally, I would rather have two 410TX by far.
It'll handle as much of the power from your amp as it'll handle--depending on your settings as always.
You can make a 20w cab sound great with a 2000w amp if you don't turn it all the way up, but it might not be loud enough to suit you.
