Spkr levels and LFE+Main ect…

Hello, im doing a recalibration, its been awhile. Should i set XO levels, distance and choose LFE or LFE+Main before setting their spl’s.
My system is 7.1.4 i do use (4) subs
I know i have to set volume to 0db and c weight, calibrate to 75db, i use an omnimic.
Your thoughts….

What is your avr/pre-pro/amp setup? The individual speaker/channel levels and delays (distance) would depend on a variety of factors you don't mention. You might even be better off with the auto setup rather than just using an spl meter. Using double bass/LFE+Main type settings is more a preference than reference thing....

Denon x4300, I scraped Audyssey, my system sounds more dynamic without it.
Its really a prepro i use 7 outlaw mono m200’s, the Denon powers the 4 Atmos speakers

Scraped or scrapped? :)

If you're manually setting it up, just manually measure the new amp/speaker setup channels and add it to settings I'd think.....but if just re-doing the whole thing, just re-do the whole thing. When using Audyssey, did you use Dynamic Volume? DynamicEQ with what settings? Audyssey and its subroutines can be useful, but not always.

It’ll be just a manual setup. My concerns will be running it through the LFE+Main setting i like, and whether or not to leave the subs on…

or turn off the subs and set levels with just each speaker ?

i really dont wanna get into a Audyssey pro and con talk, i used it for at least 20 years, tryed a few movies without it, and liked it without better. Audyssey talk can be for a different thread, thanx though…

Run your Audyssey setup to set initial levels and distances. XT32 does a very good job at that. You can turn it Aud off after and tweak to your hearts content. Hell, you can use REW or Omnimic to check the settings for distance/delay. :D That should be fun. ;)

Beyond that, I agree... LFE+main is a preference. I tend to prefer mine set to just LFE with an 80Hz cross. My mains are good to 25Hz, but the Subs are still better down low than the Towers.
Again... its just a preference...
YMMV.

Cheers!

Just try the LFE/LFE+Main setups as fairly as you can, whether one has a preference has nothing to do with actual reference (without appropriate detailed measurements and very dependent on very spefici setup bla bla bla).....just taste. Do what you like rather than what might be at your playback levels particularly might be "reference".

Back to my original or second original question haha.
if you were to calibrate using LFE+Main as a bass setting done before you ran trst tones it would seem the subs should be on during these test tones?
Or would you run test tones without the subs, calibrate the subs separately and add em later

i like that, i’ll run Audyssey, then go back with it off and check levels and add the subs….i guess it might just have some use after all

You need to test each channel on its own.
Then start combining channels.
You may well find that your mains plus subs do not sum positively, or some other deleterious effect. There are too many variables to guess what could result from what you are doing. (Or anybody for that matter, as every room behaves differently.) :)
I wouldn't worry about Surrounds plus Subs... But each main plus Subs, Center plus Subs., All...

You can always turn it off, but Audyssey, at the very least, does these things quite nicely. These settings will persist after you turn Aud off.

Remember, your Subs will usually measure further away than their actual physical measurement. Distance is actually delay, afterall, and DSP adds delays. :D

I’ll run Audyssey, then go back and compare LFE solo, and LFE+Mains to see what it looks like, i would agree do this for the main LCR

The test tones are per channel/speaker, not the playback mode particularly.

I mean, this is what I'd do. Run Audyssey and just check behind it. If you don't like what Audyssey does you can just turn it off and the distances and levels will still stick.

How are you planning to figure out your distances? You don't just simply measure it. Depending on your room acoustics and the amount of processing adding or subtracting from distance is how you adjust phase and timing.

Now that i see Audyssey has somewhat of a use for me, i can run it, then disable it and tweak levels and XO’s ect…. Good advice

Ok, i recalibrated using Audyssey and rechecked levels with Audyssey off and reset every channel to 75db @ 0db on MV.

i just watched the first 12min of OverLord 4K/HDR BR. Omg hahaha its over the top, im not even gonna check the subs it sounds so good. I had the volume to -6dbMV and it was just to much, the system didnt give up, i did, it was terrifying


i set the mains to 40hz, surrounds to 60hz and the Atmos to 80hz…LFE+Main LPF/LFE120hz

thanks for the help

Since i set my mains to small, i changed my bass management to just LFE, i did keep the low XO setting and may move it up to 60hz, but since most of my listening is around 75db im going to leave it at 40hz.

by setting my Bass to LFE+Main and then setting my mains to small i “think” it defeats the real purpose. So im just going to use LFE and the XO i chose. If you disagree, please explain, this setting gets a bit confusing, and i can easily get turned around on this stuff

I am of the opinion to let the AVR sound calibration do its thing and leave well enough alone. End of story. Then adjust any of the Audio EQ's to your liking or not.

If your in room measurements are showing no deleterious effects of the low xo, then there is nothing to worry about.
Usually, crossing that low will not achieve the best sound quality. But every room, every situation is different: the very definition of Ymmv. :)

I do like the way it sounds now, i’ll be interested to “see” what im liking when i run a few sweeps….
