Now my sub volume was at -17 after Audysessy calibration as well. Was only doing an iTunes test from the iPhone plugged straight into the AVR. Music used was Dire Straits Brothers in Arms album and Taylor Swift Reputation. Wanted to good totally opposites. Listened to both at -25 my usual music volume and set set sub volume to -21 to negate the DEQ boost and both styles sounded really nice. To me it sounded cleaner if that's the right word. Mains were more prominent and bass wasn't overpowering at least for the Dire Straits album. For Taylor it had more output but not to overpowering. I tried both with the PEQs back on and it sounded muddy and less natural. I guess it obviously different types of music will give different results. Anyway will do some movie testing over the weekend and will report back. Thanks Mike and Ray for all you great advice and patience's with us less knowledgeable folk.
That's excellent, I am really glad that you like using cascading crossovers. More clarity is exactly how I would describe the primary benefit, as well. And, you are very welcome! As far as I am concerned, we are all in the process of learning as we go along. So, someone experiments with something, shares it, and we all gain from that process.
There is something else you can try if you want to double-down on clarity. There is no telling whether or not you will prefer it, but again, it's fun to experiment. Try turning DEQ off.
If you do, you will almost certainly need to compensate by adding about 5 or 6db of subwoofer boost. Just season to taste.
DEQ boosts the bass in all of the channels, and not just for the subwoofers. Some people really enjoy the cleaner sound of their speakers playing, without that boost. That can especially apply to the center channel, where bass boosts can add more weight and chestiness to male voices. That's one of the things that cascading crossovers tries to prevent, by rolling-off the subs a little faster, so that large sub boosts won't interfere with male voices, which are mainly above 80Hz anyway. But, DEQ works against that principle a little, by boosting the CC's bass above
The surround channels have both their bass, and their overall volume, boosted when DEQ is on. (The Guide has a separate section which explains how DEQ works, and why it was designed that way.) When you turn DEQ off, it also allows you access to your tone controls, which you can use to add a little more bass just to the front speakers, if you want to. That won't affect voices, in movies at least. No guarantees on what you might like better--those are just additional tools in your tool box.
