Precision craftmanship and advanced materials
Focal's Integration ISN component speaker systems use precision craftmanship and advanced materials to deliver strong performance. And these systems include shallow-mount woofers that'll fit in the factory speaker locations in a wide range of vehicles.
Shallow-mount woofer with 2-layer cone
The ISN 100 system features a 4" woofer with a Polyglass cone that's created by depositing a layer of hollow glass microbeads over a layer of cellulose pulp. This unique material combines the warm sound of cellulose with the incredible strength of glass, for a cone that responds rapidly with extremely low resonance. A butyl rubber surround helps control cone movement and promotes high power handling. The ABS/fiberglass basket provides a non-magnetic, non-resonant housing that won't color the sound.
Unique tweeter design
Focal designed the aluminum/magnesium inverted dome tweeter to disperse high frequencies evenly for a big, open soundstage. Focal built the high- and low-pass filters into the speaker leads on the woofer and tweeter, so vocals and instruments sound natural and installation will be easier without those extra boxes to make room for.
We're always impressed by the sound of Focal speakers, and these components give you a great option for superior performance in vehicles that don't have a lot of room for speaker upgrades. You'll enjoy incredibly natural and realistic reproduction from this system, especially when combined with a good subwoofer. Woofer grilles are not included.
