An interesting idea! Questions: I have been measuring the "-1 -2 -1" according to Ian's advice, and the result is excellent. Will your suggestion of" max -3 max" do the same? (Guess I can just try, but ...) I have never seen my hi frq amp have any trouble (2x200W 8 Ohm). Same power to the woofers, and on some records with very low notes I have stop turning the volume up.Originally Posted by Tom Loizeaux
