Building on the original F300, the F300i brings enhanced treble with its improved Titanium tweeter and crossover. This versatile F300i bookshelf speaker can be used for two channel Hi-Fi or home theatre applications. Engineered into the rear panel of the F300i is a bracket allowing the speaker to be easily flush-mounted to a wall. This is a really handy feature where space is at an absolute premium, or for using the speaker as a rear effects speaker in home cinema set up.
