I have a small dilemma that I hope someone can help me with. I have Klipsch RF-63, RC-64, Rs-62, PC-13 ultra, onkyo nr-906, and 2 emotiva amps in a very open living room (living room opens to dining room, kitchen, and hallway). The PC13 sounds good, but I believe could sound much better. I was looking to pick either a SMS-1 or the AS-EQ1 for the sub. My issue is that I am not much of a techie and am afraid I might to more harm than good when tweaking the SMS-1 manually. If I use the SMS-1 or AS-EQ1 auto calibration, which one will likely yield the best results. Are either difficult to use? Also, in the not too distant future, I will likely pick up a second pc-13 for the room. Thanks.
