The BRAHMA uses the best features of vintage mouthpieces like Berg Larsen & Lawton with their small chamber & flat side-walls, but updates them with Theo’s new design technologies, which is why you will notice the interior looks quite different!
Twisted-Walls™: Flat-sidewall that ‘twists’ into the chamber.
Wave-Baffle™: The baffle is shaped in the form of a sine-wave, adding fullness and sparkle to the sound.
Theo’s proprietary “bullet” chamber: A unique ‘elongated-oval’ shape is used to transition from baffle to chamber.
Shark-Gill-Baffle™:  The arced lines on the baffle, aiding in airflow
Small Stadium Chamber: Shaped like a football stadium, this chamber provides tremendous projection! 
Shark-Gill Chamber™:  The indented lines on the chamber walls create a bigger sound. Patented by Theo Wanne.
Elliptical Window:   Efficiently focuses the airstream into the mouthpiece.
