Architectural Specification

Sonance Professional Series – PS-S43T

70V/100V/8 Ohm Selectable 4” Surface Mount Speaker

The loudspeaker shall be of the two-way type comprising a single surface-mount injection-molded ABS enclosure containing one 4” (100mm) polypropylene cone, butyl rubber surround low frequency transducer and one coaxially mounted 1” (25mm) cloth dome, chambered ferrofluid cooled high frequency transducer. It shall utilise a powder coated corrosion-resistant aluminium grille with friction-fit. Frequency range shall be 75Hz – 20KHz (-3dB). Total power handling shall be 30 Watts continuous pink noise and 60 Watts program. Sensitivity measured with 2.83 volts input at 1 meter on axis averaged between 75Hz – 20KHz shall be 87dB. The unit shall be supplied with a line-matching transformer suitable for 100 volt or 70 volt with a front-mounted control allowing user selectable power taps of 30W, 15W, 7.5W and 3.8W (70V) and an 8 Ohm bypass.  The speaker shall include a FastMount bracket that allows for a full 180° of pivot while keeping the speaker less than 1” from the mounting surface. Wire shall be terminated on the front of the enclosure via a four-pin Euro-block connector with loop-through and fed through a Protected Access Connection Terminal. The system shall be certified for UL 1480 (UEAY) and UL 2239 and conform to MIL-STD-810 for humidity, salt spray, temperature and UV IEC 529 and meet or exceed an IPX4 splash proof rating. External dimensions shall be 9.25” Height x 5.47” Width x 4.8” Depth (235mm x 139mm x 122mm). The total enclosure shall weigh 3 lbs. (1.36 kg) per unit. It shall share consistent voicing with other form factors and sizes within its product family so as to provide continuity of sonic signature when combined within a project. The loudspeaker shall be the Sonance Professional Series PS-S43T. No other system shall be acceptable unless the above combined performance specifications are equaled or exceeded.
