Conn CHR511 Double HornThe intermediate CHR511 Geyer style double horn delivers elements of Conns professional double horns to the advancing player, bringing the leadpipe and CNC machined mouthpiece receiver of the professional 11DN to a more affordable price point. The 11DN mouthpipe has a good balance between resistance and response, and the small throat yellow brass bell and branches warms the sound for singing pianos and powerful fortes.
