Yamaha NS-IC600 Ceiling Speakers were purchased to add front presence speakers to my theatre set-up so i could use Dolby Atmos sound field. The speakers came with a template to cut hole in the ceiling which was not flimsy and it was easy to hold. The speakers were a one hand wiring (push down terminals) and easy install and its hard to over tighten the mounting screws. Sound was brilliant, clear made the movie came alive with clear and precise sounds and no distortion. As the speakers are 110 Watt they easily handed the volume i like when watching a UHD movie.
