Like its predecessor, the MCi900 features a central receiver also stocked with a CD/DVD player and USB connection; and more importantly, it hosts two SoundSphere speakers both made out of a single piece of aluminum. What’s unusual about the MCi900 and its peer is that each speaker hosts a tweeter that floats on top of it—unlike most models, where the tweeter is embedded within. According to Philips, the free-floating tweeter “radiates [sound] in all directions to give a deeper, wider, sound impression.”
