The Infinity BeTA Be621 Component Speaker System is the ultimate exemplar of Infinity’s science-driven sound. The use of Beryllium delivers perfect tweeter performance due to its incredible stiffness and high damping properties. The woofer’s magnetic grille detaches for even greater volume and clarity, and allows for a perfect, seamless install. This performance is coupled with Infinity’s “Asymbalanced” Visual Brand Language via the asymmetrically balanced woofer hole pattern.
