NOT a subwoofer, the SoundTube LA808i-II is designed to increase the directivity of low frequencies in SoundTube’s Line Array system. It can be used only in conjunction with the LA880i-II 3-way line array. The use of the LA808i-II is recommended in spaces that have a large reverberation time. When a single unit is added to the LA880i-II, directivity of low frequencies is increased by up to an octave lower than with the LA880i-II alone. The product’s dimensions are identical to those of the LA880i-II. The LA808i-II must be placed either directly above or directly below the LA880i-II in order for the system to work properly. If desired, two LA808i-II units can be added: one above the LA880i-II and one below.
LA808I-II Features
Passive, fixed length, low-frequency directivity element for SoundTube line array. • Designed for use only with LA880i-II line array. • Eight 4.5” (114 mm) woofers • Extends low-frequency directivity of line array systems by up to an octave lower than with the LA880i-II alone. • Paintable enclosure is constructed of MDF and aluminum with metal threaded mounting points. • Powder-coated, paintable steel grille. • Available in black or white paint 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. • Included accessories: safety cable mounting plate and mounting bolts, Euroblock connector, safety cable. • NOTE: Mounting brackets not included.
LA808I-II Applications
In combination with the 3-way LA880i-II, the LA808i-II LFDE is ideal for PA and sound reinforcement applications. The system’s near-field to far-field transition occurs at only 3 meters (about 10’) from the speakers, maintaining a constant directivity of 40 x 120° throughout the coverage area. The LA880i-II and LA808i-II were designed for use in transportation platforms, airports, houses of worship, auditoriums, and other public gathering spaces. The LA880i-II and LA808i-II are not weatherized are intended only for indoor applications.
