The Acoustic Energy 300 Series is a real step up in driver and cabinet quality, and it's one of the most popular ranges we sell. Award-winning and well suited to small and medium-sized rooms, these speakers use bracing technology derived from the brand's Reference Series to keep cabinet colouration low.
