Hello Bob

The recording is of Frans sub. Doing the same thing as mine.
My sub is now at -5. Size is max, as that is default for all Meridian DSP speakers.

I have pushed the sub much much harder with other films and it just shrugged them off as I said in my original message.

Do you think it could be frequency dependent as Dune and Tenet are far more powerful soundtracks?
