the traynor 215 i was using has a blown cone. i have two 8 ohm Peavey 15" PA speakers i'd like to use as a backup 215 until i can get the traynor repaired. the PA speakers have two inputs on the back. in the interim, would it be safe to run them this way: SVT-CL : one output to Ampeg 810. second output to 1st PA speaker, run a speaker cable from its other input to the 2nd PA speaker. can't quite figure out what the total load would be in this configuration. the SVT-CL has taps for 2 or 4 ohms. this is a very loud band, i'll need to keep the same volume for the next week until i get the traynor back. yet another ghetto rig. safe to do this?
