3. al failure modes power test closely related to real life conditions First we use a random noise input signal because it contains many frequencies simultaneously just like real voice or instrument program Second our signa contains more energy at extremely high and low frequencies than typical actual program adding an extra measure of reliability Third the test signal includes not only the overall long term average or continuous level which our ears interpret as loudness but also short duration peaks which are many times higher than the average just like actual program The long term average level stresses the speaker thermally heat The instantaneous peaks test mechanical reliability cone and diaphragm excursion Note that the sine wave test signals sometimes used have a much less demanding peak value relative to their average level In actual use long term average levels exist from several seconds on up but we apply the long term average for several hours adding another extra measure of reliability ARCHITECTS AND ENGINEERS SPECIFICATIONS The speaker system shall consist of a 12 inch coaxial speaker combination in a paintable one piece molded polyethylene enclosure The complete system shall be weatherproof It shall exhibit 90 18 000 Hz frequency response and a sensitivity of no less than 99 dB 1 1 300 2 000 Hz band limited pink noise The system shall be capable of handling 60 watts
