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 may 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 response, the LA880i-II achieves superb coverage in an enclosure measuring only 7.56” (192.1 mm) x 41.0” (1041.4 mm) x 10.75” (273.1 mm).
Passive, fixed length, column line array with 3-way design. • Eight 4.5-inch (115 mm) woofers; eight 2.0-inch (55 mm)neodymium-motor midrange drivers; one 2.5 inch (66 mm) planar magnetics (ribbon) high-frequency driver. • Line Array - Point Source (LAPS) technology provides short near-field extent and robust farfield performance. • Paintable enclosure is constructed of MDF and aluminum with metal threaded mounting points. • Powder coated, paintable steel grille. • Available in black or white finish. • Flexible mounting options include surface-mount, pole-mount, ceiling-mount or suspended (flown). (Adaptive Technologies mounting accessories sold separately.) • Euroblock and SpeakOn connectors allow for fast connections and easy daisy chaining. • Additional low frequency directivity control with LA808i-II LFDE. • Included accessories: safety cable mounting plate and mounting bolts, Euroblock connector, safety cable. • NOTE: Mounting brackets not included.
Applications
Designed for use in large public spaces, the LA880i-II is ideal for PA and sound reinforcement applications. Its near-field to far-field transition occurs at only 3 meters (about 10’) from the speaker, maintaining a constant directivity of 40 x 120 degrees throughout the coverage area. The LA880iII was designed for use in transportation platforms, airports, houses of worship, auditoriums and other public gathering spaces. For areas with a high reverberation time, addition of the LA808i-II LFDE (Low Frequency Directivity Element) can increase the directivity of low frequencies by up to an octave lower than with the LA880i-II alone. The LA880i-II is not weatherized and is intended only for indoor applications.
