Greetings - this is my first post so aplogize if it is posted in the wrong spot. I recently picked up a Schroeder 310212 cabinet that is missing one of the 12's. Jorg uses an arragement of 16,8 and 4 ohm speakers wired in a series/parallel scheme to net at a 4 ohm load. The existing 12" is an Eminence with a 4ohm load (I assume 400W) and cannot for the life of me find another matched 4 ohm driver to add in. Wattage may also be a concern - this is a sealed enclosure and is rated (fully loaded) at 2100W - I am currenty pushing this with a Peavey CS800S which is bridged to 1200W Any suggestions or ideas on what happens (damage) if I am a bit underpowered with this beast of a cabinet? Thanks folks!
