I didn't watch the vids, but these look like they're to amplify a POD or similar modeler/amp sim. No need for a separate power amp or to defeat the cab sims in the modeler. Just run a cable from the POD to this cabinet and play your presets.
Lots of full range cabs out there, but these look a bit more accessible/familiar for a guitarist's perspective.
They're popping up for 369 Euro incluidng VAT, which usually means $369 USD, though my dealer was told by Laney it'd be something like $500.
Paul Glover made a part 2 video that explains how to use just 1 + your rig. His part 3 will highlight how to utilize just one. Seems a pretty good deal for those with the IRTStudio or with a rack based rig of low wattage.
