So shall I max out on the sub to low pass filter and shall I leave on amp LFE 120hz?. So have set the rest of frequencies correct or does is need to change? Sorry I am not much educated on this field does it mean sub dsp using the mic to collaborate.
Yes, max out the low pass filter on the sub as you are combining that (cascading) with the low pass filter the avr is providing in the crossover. LPF of LFE is normally set to 120hz so I'd leave it there. The crossovers at 110 to 150 may be a bit high considering your sub's +/- 3dB rating is 26-120hz (it may work somewhat well above 120 considering their other undefined rating of 16-240hz) but I didn't review the speaker details. I think you might want a sub with better capabilities on either end of the range for more flexibility, tho.
Yes, I noted your sub has some room eq and I assume uses some sort of mic to work. Perhaps use this dsp/room eq instead of Audyssey, or use it first then run Audyssey afterwards. I would run Audyssey just to see how well it would work (or not) for you rather than simply not using it, it should yield better results than a simple spl meter....
