5. ically swept sine input This measurement is useful in determining the accuracy in which the enclosure reproduces the input signal The combination of a premium grade woofer and the constant directivity mid and ultra high frequency sections results in a flat response as shown in Figure 1 DIRECTIVITY Beamwidth and directivity factors are derived from the 6 dB points from the polar plots see Figure 5 which are measured in a whole space anechoic environment These are specifications which provide a reference to the coverage characteristics of the enclosure These parameters provide insight for proper speaker placement and installation in the chosen environment The components of the PR 1500 are blended to exhibit a desirable beamwidth and directivity factor Figures 3 and 4 suitable for all permanent installations POWER HANDLING There are many different approaches to power handling ratings the most common being EIA standard RS 426A The derived shape of this test spectrum was an attempt to simulate the spectral content of contemporary music Although it does resemble contemporary music EIA RS 426A does not contain the same levels of very low frequency material found in live music situations Very high levels 100Hz 200 Hz 500 Hz 1kHz bii 5 kHz 10kHz 20kHz Figure 1 FREQUENCY RESPONSE 100 Hz 200 Hz 500 Hz 1 kHz 2 kHz
