LFE level with new speakers

[Dan thurston]

I'm changing my LR+C speakers to CA Min 22's and I already have a CA X201 Sub. I have a Yamaha Receiver.
My Question is when I use YPAO does the level of the sub affect the LFE level. I'm presuming the sub will have to be louder as it's dealing with more of the audio that would usually be taken care of by bigger LR+C speakers (Speakers that will go down to 80Hz)
I don't want the LFE level to be too high. I realise there is a standard level for LFE which is set in stone but will that level go beyond what it should be when the sub is turned up beyond what it normally would be with bigger speakers.
I'm guessing that YPAO sorts out the relative level of LFE to bass that would usually come out of bigger speakers.

I believe that the crossover needs to be set at 140Hz approx when using small speakers like the Min22's.

Any help would be really appreciated

If I follow the question, yes. Ypao will level match the subwoofer to the rest of the speakers. You may want to raise or lower the subwoofer trim in the AVR to suit your taste, or whatever. But it will be level matched by ypao.

thanks for the reply. Yeh I realise I prob didn't word the question very well. I guess I'm thinking is that when YPAO increases or decreases the sub level it is changing the level of the "signal level" to the sub as a whole. But if I understand correctly, the signal going to the sub is made up of partly the LFE channel and partly the frequencies that the main speakers can't do. So do you think that YPAO adjusts those 2 channels independently or does it just adjust the signal level as a whole to the sub.

For crossover setting, those little speakers should likely be crossed around 180Hz, which is stupid high, yet only 1/2 an octave below the 120Hz shown as the extension on the website.
Can your sub play that high?

 

[William Lemmerhirt]

Yep. When the sub is level matched to the rest, all outgoing signals to it will be at the volume that they were mixed at, peaks and nulls notwithstanding of course.

Thanks for that, makes perfect sense!

You're overthinking the difference between the signal coming from the crossover and the discreet .1 LFE. they should be properly level matched by your room correction.

I believe it can as it kind of part of that package. Not that I bought it as a package though.

You're sub is not very well integrated for that situation... they report a high end of only 200Hz, which is pretty normal for a sub. I don't know how much higher it will play cleanly, but for a 180 XO, you would want your sub to play cleanly up to about 240 to cover the slope of the XO.
You'll need to experiment with lower settings, but be aware that depending on the physical limits of the speakers themselves, you may be pushing their limits with lower XO settings.
By how much, I cannot say.

Yeh that was my question really, do those 2 things get level matched as part of the room correction. I'm assuming that they do from what your saying. Which is good really because there's no way of doing it manually on my receiver. The only thing I can do manually is adjust the level of the output going to the sub.

Cheers. I can only hope they will go together because CA do sell a home cinema package containing 5 min22's and the x201 sub.

Think of the sub level as a combo of LFE and redirected bass and that the level is being properly handled by the avr based on the volume level and the sub trim level. In some avrs you can change LFE level particularly (pretty sure I can on my Onkyo), tho.

Thanks that’s really helpful.

I’ve checked and I can only adjust/trim the level of the sub as a whole. I can’t adjust the balance between redirected bass and LFE. So I can just hope that the AVR does get that balance correct.

With my bigger speakers I set the crossover to 80hz so if I turn the sub level down it doesn’t make it sound like laptop speakers!
