SoundTube - LA880i-II - Line Array Column Loudspeaker (Single)


SoundTube - LA880i-II - Line Array Column Loudspeaker

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. Featuring eight 4.5-inch woofers, eight 2-inch midrange drivers, and one 2.5-inch planar magnetics (ribbon) high-frequency driver for an extremely smooth high-frequency response, the LA880i-II achieves superb coverage in an enclosure measuring only 7.91" x 40.87" x 11.99".
