Hello all, I am a newbie here in this forum and this is my very first post, so please be gentle. I am currently running a full Athena set up off of my entry level Pioneer VSX-D510 Receiver. Front: 2 AS-F2's Center: 1 AS-C1 Rears: 2 AS-B1 No sub at the moment While I am waiting to pick up a sub, I am wondering what I should set my crossover at. I have 3 options on this amp. 100HZ, 150HZ and 200HZ. Also, I was hoping someone could clarify for me how the LFE attenuator setting works? Any help is much appreciated.
