SoundTube - LA880i - Line Array Column Loudspeaker (Single)

SoundTube - LA880i - Line Array Column Loudspeaker

SoundTube LA880i&808i

The SoundTube LA880i 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 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.

The LAPS technology in the LA880i makes the speaker’s near-field shorter than most other line arrays. Because its effective line length is kept relatively constant as a function of frequency, the near-field to
far-field transition occurs at only 3 meters from the speaker. Beyond this distance, there is no change in the frequency response or the directivity pattern of the speaker (40 x 120 degrees).

Featuring eight 4.5-inch woofers, eight 2-inch midrange drivers and one 2.5-inch planar magnetics (ribbon) high frequency driver for extremely smooth high frequency response, the LA880i achieves superb coverage in an enclosure measuring only 7.91” x 40.87” x 11.99”. Numerous mounting options allow the use of the LA880i on walls, near ceilings, on poles, or suspended via cables.

Optional Addition to LA880i:

Additional low frequency directivity can be achieved with the addition of the LA808i LFDE (Low Frequency Directivity Element). NOT a subwoofer, the LA808i adds eight 4.5-inch woofers to the system to extend the directivity control by up to an octave lower in frequency than with the LA880i alone. Its use is recommended in areas with a high reverberation time. (See options menu to add this option)


SoundTube LA880i Applications

The LA880i is ideal for PA and sound reinforcement applications wherever large groups of people may be present. Typical applications include large houses of worship, university lecture halls, transportation centers such as train platforms, and airport terminals. In highly reverberant situations, adding the LA808i LFDE will improve low frequency directivity in the space.
