The W2 subs are the passive ones and the X1 is a part of the U2 package deal for the Evolution lines. I am planning to use the pre-out from the processor to the input of the X1 then from the hi-pass output L/R of the X1 loop back to the multi-channel amp and the sub-output L/R of the X1 to the each channel of two of the A1 amps . The X1 crosser set at 80hz. I guess the connections are too cumbersome but according to NHT that will give the M5s and the W2s the best blend-in. Also, the sub-out from the processor is connected to the X1's LFE in. Would you recommend any other better way to simplify my connections. You are right though. I probably do not even need the X1 if I use the sub-out from my processcor. Well, shed me some light here, I am getting dumb and dumber with my age.
