So I can’t believe I’m asking this, but…..what Genzler cab for metal?

But seriously, my son is playing in an original, tuned down metal band and needs to get a something better than his 150 watt Fender 115. They tune down to C and he runs a dirt pedal pretty much all the time. He’s competing with his guitarist’s 412.
It needs to fit into the backseat or trunk of a 2011 Chevy Malibu. Also, he’s 19 but seems to hurt his back a lot so I was thinking light or modular. I was going to lend him my Magellan 800 and Berg HD112/212 stack for an upcoming show but he doesn’t want to deal with moving the 80lb HD212 (neither do I these days).
Thinking a Magellan or Nu Classic 212 but not sure which one is voiced better for tuned down metal? He’s not a gear guy and I’m out of the loop on bass gear not to mention I have no idea what kids are using for that sort of music these days.
Any recommendations are welcome. Cheers!
