Thanks for your reply Marvin

That is very interesting, and helpful information.

I have quite a few tracks which are very bass heavy and have never noticed the issue with music.

I think it's fair to say that if a single DSW bottomed out occasionally but rarely, we would probably accept it to a certain degree, if the volume was very high.
Two Dsw's sharing the load, No. It shouldn't happen.
But FOUR Dsw's, that is crazy and I would say, proves that it is a specific frequency, which is definitely not even that deep, and therefore completely fixable.

If any of you have 'The Hobbit, The desolation of smaug' on 4k, try the battle scene at the end.
Bilbo runs into a hall and smaug smashes through the wall. It goes quiet as the flag drops to the floor. When the flagpole hits the floor the Dsw's pop. It's definitely not sub bass, but causes the issue.
I have reconfigured and recalibrated my settings dozens of times at different levels but it still happens.

Hopefully Meridian can come up with a fix.

Cheers

Nick
