Why not turn it to 30+?!? I believe it goes up to 45 or something. I usually play mine around 30 (ML) but I like it loud. Is there something magical about 20 that I'm missing?

 

In my '11, 62 is the highest and then the display simply says "Max".

the basic system is good but not great. how high does the ML system go ?

 

Checked last night and it's the same - 62 is highest then Max. I had to turn the sound down to almost zero on my iPhone so I could turn the speakers all the way up to test. WAY too loud with iPhone at full volume, even at 35.
