I have a great question! I already run a 1001RB II - Currently pushing a discontinued Ampeg SVT 412HE ..Which is a great cab but a complete horses ass to move around. I gig around 4 to 6 times a month.. Need lees to say I'm looking to stray for the 95lb 412 cab and move to a Neo 212 . .. . Which in lies the question. I need the volume and need to know if the 212 can come close to what my 412 can do? The Ampeg is a 400watt (800 watt program ) 4ohm Cab so I get the heads full power in terms of Watts.. With pairing the 1001 RB II with The Neo 412 will I get enough Volume considering I'll be using less watts from the head running it at 8 ohms...and having a Larger 600 watt over head on the cab? I'm not the greatest at comparing such weirdly different specs! Any help would be awesome!
