SoundTube LA880I-II-WH 3 Way Line Array Speaker (White) - 4.5"The SoundTube LA880i II is not a typical line array column loudspeaker. It is an advanced LAPS (Line Array Point Source) 3 way design that provides a very short near field extent and robust far field performance. Frequency tapering of low and mid frequency pass bands allows the LA880i II to maintain a more consistent ratio of array height to radiated wavelength, ensuring a stable vertical beamwidth that out performs many other single box line arrays.
