The ISU165 is a 165 mm 2-way separate speaker kit from Focal’s Universal range featuring an inverted aluminium/magnesium tweeter and built-in filters. The kit’s compact drivers and redesigned chassis prioritise integration with factory locations.

With a shallow mounting depth of 48.9 mm the ISU165 is intended for original-fit locations and is designed to connect to factory head units without major interior modifications, allowing speaker upgrades where space is limited.
