It is also an excellent choice for nearfield reproductionwhere extreme low frequency response is not required. Ultra-compactdesign and surprisingly high output make it an effective component oflarge-scale multimedia systems in a broad range of venues and applica-tions.This “micro” system is engineered for high quality distributed soundsystems of all types. The vented enclosure extends effective low fre-quency response. A 1" soft dome tweeter produces exceptional clarityand definition. The complex crossover uses computer-optimized asym-metrical filters to smooth on-axis frequency response as well as powerresponse.OTHER RELEVANT DOCUMENTS• Group I Hardware Technical Specifications*• Group I Price Lists• APP Testing Procedures*• Water Proofing Technical Specifications• Structural/Mechanical Technical Specifications*ARCHITECTURAL SPECSSPECIFICATIONSFrequency Response±3 dB 98 Hz – 20 kHz-10 dB 60 HzAxial SensitivitySPL 1w @ 1m: 91 dBImpedanceNominal 8ΩPower HandlingAES 180 Watts100 Hour Sine Wave 90 WattsMaximum OutputLong Term 110 dB SPLPeak 113 dB SPLNominal Coverage Angles (-6 dB)Horizontal: 120 degreesVertical: 120 degreesAdditional Descriptive DataLF Subsystem 1 x 5.25" VentedHF Subsystem 1 x 1" soft-domePowering Mode PassiveFinish: Black Catalyzed PolyurethaneConnectors: 2-pin Barrier StripGrill: Vinyl Coated Perforated SteelDimensions & WeightsHeight: 10.75 in (273 mm)Width: 6.375 in (162 mm)Depth: 5.75 in (146 mm)Net Weight: 9 lbs. (4.05 kg)Shipping Weight: 10 lbs. (4.5 kg)The two-way full range loudspeaker system shall incorporate one 5.25-inch cone low frequency transducer and one 25mm soft-dome highfrequency transducer. The total system shall meet the following perfor-mance criteria: Frequency Response of 100 - 18k Hz ±3 dB; Axial Sensi-tivity (1 W @ 1 m) of 91 dB SPL (LF); 100 hour sine wave Power Han-dling of 90 Watts, AES method Power Handling of 180 Watts; Hori-zontal coverage of 120 degrees between 6dB down points; Verticalcoverage of 120 degrees between 6dB down points.The system’s low frequency driver shall be loaded into a vented enclo-sure that provides optimally controlled acoustic diaphragm loading. Aninternal passive frequency dividing network shall provide a fourth orderacoustic crossover between the low and high frequency subsystemsand shall incorporate system equalization. The crossover shall be de-signed so that maximally flat frequency response is obtained.The enclosure shall be rectangular in shape and constructed of void-free cross-grain-laminated birch plywood with internal bracing. It shallbe finished in a black catalyzed polyurethane coating. The front of thesystem shall be covered with a protective perforated steel grill assemblycoated with vinyl to dampen resonance. Mounting hardware attach-ment points shall be located on the top and bottom of the enclosure.Attachment points for Omnimounttm brand 75 series mounting hard-ware shall be located on the rear of the enclosure.The two-way full range loudspeaker system shall be the EAW modelUB12.ACOUSTICALPERFORMANCEPARTNERSHIP
