The top half of the maget is not even contributing! I would reassess.
What is your required gap width and depth, and what overall size constraints are you working in? I'll see if I can perhaps give you some alternative ideas...

I need a gab of 8mm depth and 3mm width. My constraints is that I have to put another same magnetic circuit on both side with opposite magnetic field. The distance beetween the airgap must be 9 mm.
Thanks for help me.

Poobah, I've done simulations whith thinner magnet and thiner steel, and of course field in air gap decrease.
If you require such a wide gap with such a thin overall profile constraint, then you won't be able to get much more out of the motor. You can only improve it with thicker steel, and thicker overall design.
While I think the point is moot now, someone mentioned silicon steel from transformers. Transformers are designed for low hysteresis and low remenance - neither is much of a factor in a speaker circuit. Low carbon (1006-ish) steel is best commonly available material for this.
And what do you think about supermalloy in this design??? in femm it's the best field I can reach...
