Thanks. Extreme as in... too much support and I should go higher?
The sub channel is actually the LFE channel. You have to be very careful using regular speakers supporting the sub/lfe channel. As a general rule, many speakers shouldn’t be used to support subs/lfe.
I’d think with those speakers 50Hz would be sufficient. If your subs hammer out good response don’t support LFE, if your subs need help between 100Hz and 120Hz like mine support away up there. Use the sliders or manually enter to limit like a surgeon which support goes where, then use level to avoid boosts you don’t like (if there are any). And overlap support a little if you decide to get surgical, don’t end one at 60Hz and start the other at 60Hz use a little blend.
Thank you. Helpful advise. So if I just avoided any speakers supporting the LFE, what is the difference if I support other speakers down to 50hz...? Wouldnt the mains supporting the center or rears or atmos down to 50hz be the same as supporting the LFE down to 50hz?
What is a better approach, increasing the hz to avoid the sound OR decreasing the support?
There can be a lot of output required and LFE is boosted by 10dB making it quite difficult for speakers to handle the output. So you can reduce the level of support for speakers if you want to support LFE.
Not all speakers just to throw my 2c in. His maybe, could be something else with boosts elsewhere too. Without seeing all of it laid out we can’t tell. All my speakers support LFE just fine, 50 HZ and up. As with everything, it depends.
Of course. I have done it as well and it worked with my speakers at the time as well… however it could be an issue supporting lfe with speakers depoending on…
L/R/SL/SR are all supporting SW1/LFE in my configuration with great success.
Keep in mind that the LFE output will be LFE+Support - so for any specific SPL, the LFE will be working LESS...
But… change to an +8-10dB house curve on LFE, and then listen between reference level and I think speakers start to show signs of stress. I guess what I am saying your house curve, and listening level should play a large consideration and part of your thought process when setting your speaker support level and how low they support is all. I could see some situations where speakers would start to fall apart.
Sounds like the amplifier is running out of power or something is clipping the output signal.
Thanks for your input
I don’t think that’s necessarily why it can work for some. So many variables we usually don’t know like room size, SPL wanted, listening distance, and what the room is doing. Consider maybe your mains are trying to boost a surround of yours or an overhead, maybe (this is all hypothetical) if you removed the mains from supporting that made up scenario they would handle everything else fine, including LFE. If you just remove them supporting anything else and crank that movie I would imagine everything would be fine. If so slowly add them in to supporting other speakers that need their help until you find too much again. Then you can either reduce the support levels to keep them in line or compromise and not support something. It’s not that your mains are poor, you might just be asking them to play 10 channels worth of signal at once and they’re just not happy. Should be an easy fix for you.
1) During Dirac speaker calibration, the SW should be level w/the other speakers and not have any "boosting".
I remeber seeing Joss Walker saying it doesn’t matter that the speakers match when setting mic levels, Dirac takes care of it. You just need 20-30db over the noise floor for each speaker. One could be 40 and the other 25 and it matters not one bit.
