The Altec Lansing FX6021 with InConcert technology is a 3-piece system for the music, gaming, or home theater enthusiast. A revolution in pro audio, InConcert technology enables the FX6021 to deliver crisp, clean, full-volume sound that feels like its being directed right at you. InConcert Technology directs the sound straight ahead and to the sides, not up and down. So the sound is pure and clean, uncluttered by reflections from the ceiling or floor. Two ultra-slim satellites feature a total of twelve 1” neodymium micro drivers, with each pair of micro drivers powered by its own discrete amplifier. A 6.5” ported subwoofer completes the sound with low-frequency, full-throated bass.
