Conn Double Horn in F/Bb CHR511



Find a Dealer


The intermediate CHR511 Geyer-style double horn delivers elements of Conn’s 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.


Additional features from Conn’s professional lineup include the mouthpipe water key, adjustable finger hook, and reversible change rotor.  These make performance more comfortable and customizable, setting up the intermediate musician for success.  To protect the CHR511 from the rigors of daily transport, the instrument ships in a durable ABS case with easily replaceable handle and feet. 


Each CHR511 is inspected and set up by Conn Selmer technicians in Elkhart, Indiana, and is held to the same exacting standards as Conn’s professional instruments.
