Okay I eventually connected my tested Tannoy red readers to my Rebel. So far so good, that sound but the connections... Now I need to work on integration and crossover. This time I'm willing to do it completely different. I have no control over my Twitter harmonics as I am not driving it by set amplifier and I cannot play with loading. Also, I need to figure out how whatevet  I know about crossovers would be applicable to ampX topology. I know how to crossovers act in terms of sounds but I have no experience how transparent crossovers for X Factor 

This would be very interesting research. Most likely it will be first order, I might get better sound but it my diminished whatever I call X Factor.
