2 way bookshelf or wall mounting speaker,

Packing a punch well beyond its diminutive size the versatile F300 can be used for two channel or multichannel applications. Pre-fitted to the rear panel of the F300 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.
