DESC: Designed to satisfy music as well as movie lovers, the 2-Way Floorstanding Speakers from Pioneer, combines a smart, slim design with precise sound reproduction. Featuring a rounded enclosure, which increases rigidity and prevents unwanted sound from enclosure diffraction. Phase Control technology manages time and phase response of the speakers to minimize the effect of sound delays usually due to the filtering process of multi-channel recordings. A down-firing bass-reflex port improves the low frequency response of the floor-standing speakers, whereas Pioneer's unique ABD (Acoustic Balance Drive) and AFAST (Acoustical Filter Assisted System Tuning) simulation technologies eliminate vertical standing waves, resulting in precise and dynamic bass with no low midrange coloration.
