Description

NOT a subwoofer, the SoundTube LA808i 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 3-way line array. The use of the LA808i is recommended in spaces that have a large reverberation time. When a single unit is added to the LA880i, directivity of low frequencies is increased by up to an octave lower than with the LA880i alone. The product’s dimensions are identical to those of the LA880i. The LA808i must be placed either directly above or directly below the LA880i in order for the system to work properly. If desired, two

LA808i units can be added: one above the

LA880i and one below.

Applications

In combination with the 3-way LA880i, the

LA808i LFDE is ideal for PA and sound reinforcement applications. The system’s near-field to far-field transition occurs at

Line Array Speaker

Preliminary Technical Information for System Engineers only 3 meters (about 10’) from the speakers, maintaining a constant directivity of 40 x 120 degrees throughout the coverage area. The LA880i and LA808i were designed for use in transportation platforms, airports, houses of worship, auditoriums and other public gathering spaces. The LA880i and LA808i are not weatherized and are intended only for indoor applications

Technical Data and

Specification Tools

Technical Data

SoundTube Entertainment strives to provide complete and effective technical information and data to dealers, engineers and designers. All data are available from

SoundTube Entertainment or at www.

soundtube.com.

Technical data and downloads include:

EASE™ data – 3-D polar plots.

EASE™ Address – 2-D modeling for distributed systems

Autodesk® Revit® software

Tech Sheets – Technical information and architectural specs for system engineers

SoundTubeSPEC™ – Proprietary speaker placement software

Data Acquisition

All data for SoundTube speakers are independently collected from and verified by

NWAA Labs (www.nwaalabs.com) using their proprietary MACH testing system. All data are collected and analyzed according to ASTM, ISO and AES standards using

EASERA, TEF and MLSSA. Full balloon data including both phase and magnitude is compiled into a variety of formats including EASE 4.x, GLL and CLF.

Architectural Specifications

The loudspeaker (LFDE unit) shall be used to enhance the low frequency directivity of a single-cabinet 3-way line array. It shall consist of a single cabinet with eight 4.5 inch (115 mm) woofers. The cabinet shall be the same size as the cabinet housing the

3-way line array.

In tandem with the 3-way line array, the performance specifications of a typical production LFDE unit shall be as follows: usable frequency response shall extend from 75 Hz – 22 kHz (-10 dB). Measured sensitivity (ref. 2.83 V / 1 m) shall be 95 dB.

The speaker shall have a rated impedance of 4 ohms. Rated power handling shall be

500 watts and maximum continuous output at 1 meter shall be 112 dB.

The eight low frequency drivers shall include a treated paper cone and butyl rubber surround. They shall use a die cast aluminum basket and a ferrite motor structure.

The midrange drivers shall include a treated paper dome with pressed foam surround.

They shall use a die cast aluminum basket with a neodymium motor structure. The high frequency driver shall be a planar magnetics (ribbon) unit with a neodymium motor structure.

Mounting points for wall mount, pole mount, ceiling mount or suspension via cables shall be provided. Mounting hardware shall be Allen Products or equivalent. Input connectors shall include a four-position terminal block and Neutrik

SpeakOn. The four-position terminal block shall accept from 10 – 22 gauge wire. A jumper cable shall be provided to connect the LFDE unit to the 3-way line array. Builtin low frequency equalization shall automatically be applied to both the LFDE unit and 3-way line array when the two units are properly connected together using the jumper cable.

The enclosure shall be constructed of MDF and plywood with metal ¼” x 20 threaded inserts mounting points and a steel grille.

The enclosure and grille shall be available in black or white textured paint, and shall also be paintable by the installer. A bent back plate with plate mounting hardware and safety cable attachment point shall be included. Speaker mounting brackets and hardware shall be available for use with 3rd party manufacturer mounting systems.

The system shall be the SoundTube LA808i

Low Frequency Directivity Element in conjunction with the SoundTube LA880i line array
