Hi,redbarchetta,
this bass mudness happend very often with the yamahas and has imo 2 causes:
The yamaha ( HS 50m speaker are önly 5 " and so they don´t
build the exact bass area .
Even my HS 80 m ( which I really like ) have a one flaw,
this is the bass area ( - ca. 200 Hz)
What I do to work arround this flaw is ,that I hear a reference mix of a very good
mixed professionel song,and than mixing so long till my song sounds nearly or equal to this reference song.
All that on the Hs 80 m ,you know..........
If one makes this often,once you will find yourself in the situation not to need a reference mix any more.
Another idea is to buy better monitor´s,
but really better ones cost 1000 bucks and more,
the yamahas are imo in that price range a gift!.
Have fun
Pragi
I forget to mention that the reference song should be of the in same
style then the song which has to be mixed!
