Product Research


Overview: The Focal 100 IC6ST is a two-way, stereo in-ceiling speaker designed for small to medium sized rooms in home applications. It can be used in distributed systems, like hallways and living areas, stereo systems for living rooms and bedrooms, as well as overhead speakers in a home theater system. The IC6ST is even ideal for humid environments such as a bathroom or kitchen.

Design: The 100 IC6ST features a 6-1/2" dual voice-coil Polyglass cone midbass driver and dual 1" aluminum inverted dome tweeters. The speaker's compact unibody and new crossover were designed to improve sound dispersion and off-axis listening, helping to avoid the "shower effect". The tweeters can be rotated and include a 3-way switch for adjusting the output level according to the acoustic environment with selections of -3dB, 0dB, and +3dB. Each speaker comes with two paintable, magnetic, metal-mesh grills; square and round. Small magnets around the rim of the speaker allow the grills to be easily placed and removed with no tools required. Two sets of spring-posts are provided for attaching speaker wire.

Installation: The Focal in-ceiling speaker includes 3 integrated mounting brackets with optimized grips. These allow the speaker to be locked into place by simply tightening the 3 Philips-head screws after placing speaker in the opening. As the screw is tightened, the arms will swing outward and press against the backside of the drywall or mounting surface. The screws remain attached to the mounting arms, even when fully loosened, preventing them from falling out and making for an easier installation.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

Because Focal is AWESOME !! I will try the 6" and if this is what I need, then I will purchase more. If this doesn't quite deliver the sound, then I will return them and upgrade to the 300 ICW 6, even those don't get it.. then 100 ICW 8, still lacking, then I know 300 ICW 8 will get it for sure... I have had top of line car speakers and the sound was second to none... I have 16 Zones to outfit... 32 x each speaker price $$$$$... so, sound experimentation... pretty critical to the wallet...
