I have two MAG Ashdowns that are connected by the effects send of a MAG 600 to the low gain input of a MAG 300. The bass is plugged into the 600 (drives two Avatar 210s). The 300 drives a 4 ohm Avatar 210. No effects. The 600 is regular tone and the 300 is either the same tone , or trebley , or extra midrange. The effects send (or tuner out) is loud and bright. This stack is tall, like yours . It does not take up much stage width.
