[. . . ] F R i SPEAKER SYSTEMS MANUAL F R i SPEAKER SYSTEMS Welcome Dear Sound Professional: Thank you for choosing EV products. For more than 70 years, we have persevered to design, engineer, and manufacture the most innovative and highest quality audio products for indoor and outdoor spaces, including offices, houses of worship, live music venues, auditoriums and stadiums. This perseverance has led to our pioneering new technologies that have become industry standards: constant directivity horns, manifold technology, Variable-D® microphones, hum-bucking coils for microphones, and the inclusion of ultra-light weight neodymium in magnet structures (previously only utilized by the auto industry) for microphones and loudspeakers, to name just a few. It is our pleasure to provide you with the audio solution best suited for your critical sound reinforcement needs. [. . . ] A total of twelve 3/8-16 threaded mounting/suspension points shall be provided, (three each on top and bottom, two per side, two on rear). The front of the loudspeaker shall have a powder-coated perforated 16 GA steel grille. Grille mounting shall allow for acoustically transparent fabric to be applied without any noticeable protrusions or fasteners. The two-way full range loudspeaker shall be the Electro-Voice model FRi-122/64. FRi-181S The subwoofer loudspeaker system shall incorporate one passive or biampable 18-in. LF transducer mounted in a vented, slot-loaded enclosure tuned at optimum low frequency response. System frequency response shall be 45 Hz to 160 kHz (-3 dB) measured on axis. The loudspeaker shall produce a sound pressure level (SPL) of 97 dB (100 dB half-space) on axis at 1 meter with a power input of 1 watt, and shall be capable of producing an output of 123 dB (132 dB half-space) on axis at 1 meter. The loudspeaker shall handle 400 watts of amplifier power long-term (EIA Standard) and shall have a nominal impedance of 8 ohms. The loudspeaker enclosure shall be trapezoidal in shape with side draft angles of 7. 5 degrees each. It shall be constructed of 13 ply void-free cross-grain-laminated Birch plywood and shall employ extensive internal bracing. It shall be finished in black or white acrylic paint or available unfinished. Input connectors shall be two 2 terminal barrier strips. A total of sixteen 3/8-16 threaded mounting/suspension points (4 each top, bottom, sides) shall be provided. The front of the loudspeaker shall have a powder-coated perforated 16 GA steel grille. Grille mounting shall allow for acoustically transparent fabric to be applied without any noticeable protrusions or fasteners. The sub bass loudspeaker shall be the Electro-Voice model FRi-181S. 4 FRi Series Warranty F R i SPEAKER SYSTEMS Uniform Limited Warranty Electro-Voice products are guaranteed against malfunction due to defects in materials or workmanship for a specified period, as noted in the individual product-line statement(s) below, or in the individual product data sheet or owner's manual, beginning with the date of original purchase.

Electro-Voice shall not be liable for any incidental or consequential damages including, without limitation, injury to persons or property or loss of use. [. . . ] If multi-box arrays are used in a stereo configuration, the recommendations for mono program configurations apply to each side. To increase low frequency response, consider a hard-surface coupled mounting surface of the sub(s). Acoustically coupling low-frequency cabinets to architectural structures provide an extremely cost effective means of providing more low-frequency energy in your system without additional loudspeakers or electronics.
