Ultimate wireless experience.

Like the FS 409 from which it derives, the AIR-X 409 delivers top-tier performance in an elegant, wireless package. The 3½-way, bass-reflex design renders the whole sonic spectrum flawlessly, all in a contemporary package without the complexity of speaker cables and outboard amplification. The Crystal Membrane midrange drive unit, combined with the JET 5 tweeter, present an open sound that incorporates the acoustic characteristics of the surrounding space while maintaining excellent resolution. Formidable bass is reproduced by a pair of 180 mm woofers that recreate the most challenging musical material, in every key and even in the largest rooms.
