Funktion-One SB10-WR Weather Resistant Compact Bass Loudspeaker - 10"Utilising the same design principles as the SB8, the larger SB10 provides higher output and deeper bass. Perfect for applications where a conventionally sized subwoofer is too large and obtrusive, such as bars, restaurants, retail and galleries. The compact size of the SB10 also makes it suitable for domestic applications, such as a dynamic and precise LFE channel in a home theatre system or as bass extension for the F5. 2 or F81. 2 in a 2. 1
