The intermediate SFL511 series of flutes features a professional hand-cut headjoint made of the finest grade American sterling silver, hand-assembled keywork, Pisoni Lucien Deluxe pads, and a body comprised of premium Japanese nickel silver. The headjoint design for these flutes features a sharp blowing edge, steep drop-off lip plate, and multi-tapered bore for fast and effortless response and articulation. The under and over hand-cutting provides a rich, expressive tone that is even throughout all the registers and gives the performer extreme dynamic control.

The keywork on the 511 series of flutes has the highest specifications and tolerances alongside carefully adjusted and balanced German steel wire springs. This ensures the 511 series have a feather-light, lightning-fast, and fluid key action. French pointed key arms connect at the back of the key cup and extend to the center guaranteeing greater strength, stability, even pad wear, and ultimately less overall maintenance. All Selmer flutes are professionally set up, play-tested, and optimally adjusted at the Conn-Selmer Woodwind Factory located in Elkhart, Indiana.
