So, you can do the max-level procedure you mentioned, at +15 or 0 (your choice), but what you’re probably going to find is that the sub ends up exceeding loud compared to the main speakers.
Perfect!!! As long as theres no damage to my subs or im not sending them a dirty signal id prefer it to be bass heavy. Hell im purposly picking out bass heavy movies just to hear my subs. Im sure ill want better sq later in life but for now all i wanna do is BUMP!!!

Just to be perfectly clear the "max level procedure" your talking about is the one i mentioned to you right?

Im soo excited!!! Thanks for your time and info!

Btw i call you "young wayne" in my head. Lil wayne refers to himself as that in a song and i think of it everytime you reply! Haha peace!

Say wayne, what if your speakers (left right) on your avr clip at a lower volume than your subwoofer pre out? Would you set your external amp (for subwoofer) gain according to the safe volume before speakers on the avr clip ( since you wont go past that volume anyway) or the safe volume before the avr's subwoofer pre out clips? I dont know if my speakers clip at a lower volume than my pre out im only asking because i know its the case for most car audio head units. I wont know till the first when my oscope comes in if its the case for me. Either way, whats the correct answer?

Re: Gain Structure for Home Theater Discussion Thread

If the mains distort before the sub amp clips, then the sub system obviously has more power than the mains. As such, there’s no gain structure requirement because you’ll never drive the sub amp into clipping in normal use, or even in “abusive use” where you were intentionally driving the mains to distort. So simply adjust the receiver’s sub output and the sub’s gain knobs appropriately to match and blend with the main speakers.

Wayne

Ok. Got my oscope in today. As expected my right left speaker terminals on my receiver clip at volume 64/80 and the sub out 73/80. So to be clear i would set my external subwoofer amplifier's gain with the safe volume of 63 not 72 correct?

Btw for anyone googling when the pioneer vsx-519v-k receiver clips it is @ volume 64/80 for left and right speaker terminals and 73/80 for subwoofer out.

Thanks a"gain" wayne!!!😁😁
