So you want as loud as possible and money is no object?  Wait till CES in January and then look at Adire's offerings.  The CEO of Adire showed us a hint of what they have in store for one of their drivers.  This included a BL curve for it  that was perfectly flat out to 75mm one way, BL up in the 43 Tm all the way throughout that range, and he called it one of his medium throw drivers he is releasing.  This thing should prove to be an SPL monster.  So their medium throw driver will be linear over 6" both ways.
