Just got off the line with Brent(Nice Fellow)at Axiom and inquire about the Resistor. He says it involves some precision installation...saudering; proper alignment. He doesn't really recomend it. Highs will be sacrificed in a negative way. I don't think I'll be doing that way. He said if the felt way is working fine then by all means keep it in. I ask him how much each tweeter costs and its around $58.00. Not bad.
