Hi I have a schroeder 500 watt 8 ohm 112 cabinet. I have 4 bass heads: 1.) Markbass LMIII 500W@4ohms 2.) Peavey TOur 700 700W@4ohms 3.) Peavey VB-2 225W All tube (Switchable(2,4,8) Ohmage) 4.) Carvin B1500 1250W@4ohms Which one of these would be the best match for the Schroeder power and sound wise? I want to safely and musically crank the cab to it's full potential.
