+10dB LFE Amplification not working

[NMixes]

Hello everyone!

I have "10dB Amplification of LFE" checked on my speaker setup but the simulated result doesnt reflect that (confirmed by measuring with REW) is there a setting I'm missing? It used to work before

Did you check "10dB Amplification of LFE" before or after linearization with REW?

It's checked before creating the filters in Audiolense, when appying the filters and measuring with REW it shows the same result as the prediction.

How do you confirm it with REW?

The 10dB amplification is only for the LFE input channel, so you will not see it if you measure left or right front channels.

Unfortunately I don't know Audiolense.

Typical room EQ systems will try to equalize ups and downs in the overall frequency response, including the sub/LFE. In other words, if you first select +10dB for the LFE and then run REW or similar (Audiolense?), it will interpret it as an unwanted non-linearity and equalize it away. That way you would get the response that you pictured above.

If you want your LFE to bei 10dB louder than the other speakers, you should run REW (Audiolense?) first without activating the extra amplification and switch it on only after applying the EQ that REW/Audiolense calculated.

By measuring the LFE channel

not using REW to EQ, just for measuring

Yes that looks odd. Please send me the measurement and I'll try to sort it out.
