How to tell if your mouthpiece has a large chamber

What is a True Large Chamber?

True Large Chamber mouthpieces have significantly larger chambers than the bore. They also have significantly rounded inner side walls that extend all the way to the tip. This is done to allow the sound wave to spread width-wise in the mouthpiece creating a robust, rich, and warm sound.  A medium chamber is where the chamber is the same size as the bore and a small chamber is where the chamber is smaller than the bore.
