![]() The speakers are nominally 8 ohms impedance, so your total wire resistance should be no more than 0.8 ohms.ġ4’ Hanging Height 17.7’ (5.4m) Apart 21.5’ (6.6m) Apart FIGURE 2: SPEAKER SPACING When using Sonance Professional Series loudspeakers in an 8 ohm system the total wire resistance should be less than 10% of the speaker impedance. Speaker Spacing in Feet for a Distributed Audio System Standing Listenerġ2’ Hanging Height 13.7’ (4.2m) Apart 17.5’ (5.3m) Apart For example, a 100 watt load can go 700 feet on 18 gauge the same load may be placed on 1100 feet of 16 gauge. Stepping up to 16 gauge wire extends the allowable run length by approximately 35%. Conversely, if you halve the load, you may double the acceptable wire length, i.e., a 50 watt load is safe over 1400 feet of 18 gauge. If you double the load (sum of your tap settings), you will reduce the footage by half, to 350 feet. Wire length using 18 gauge is appropriate up to 700 feet with a 100 watt load. The wire starts at the amplifier location and is paralleled at each speaker location. WIRE GAUGE – 70V/100V SYSTEM The most common wire used on commercial 70 volt systems is 18 gauge, 2 conductor, stranded, and jacketed without a shield. The calculations are based on +/- 45 degrees of coverage from the speaker, and listener ear heights of 62” for standing and 40” for seated. The chart below (see figure 2) shows how far apart the speakers can be placed in a distributed audio system. Sonance Professional series speakers possess extremely smooth and predictable off-axis frequency response. To calculate the amount of usable power an amp offers, simply multiply the rated output by. Therefore, a standard 100 watt amp would safely drive this load. To arrive at the needed power for this number of speakers, simply divide the total load by. For example, if there are 5 speakers and the taps are set at 15 watts, the load would be 75 watts (5 x 15 watts = 75 watts). The sum of the tap settings should never exceed 80% of the amplifier’s rated output. When choosing an amplifier the maximum number of speakers and the output level of each speaker must be known.
