- W3010226572 abstract "This paper work describes a study of a loudspeaker sound level and its modes of vibration using different impedance. Results obtained show that diaphragms that utilize a flat or shallow height produce higher frequencies, as opposed to deeper heights which are better for lower frequencies. In other to get the similar sound level, 4 ohms require more while 8 ohms require less powerful amplifier to arrive at the same maximum output when compared to 16 ohms. The lower the impedance the higher the power handle and the lower the sensitivity numbers. 4 ohms speakers place a significantly heavier demand on power amplifier as compared to 8ohms because of their lower impedance, twice as much current will flow through a 4 ohms speaker as compared to the 8 ohms and 16 ohms respectively. For a given volume setting, also comparing the three cones with different impedance, it was observed and evident that the 16 ohms impedance cone when mounted on the same rated permanent magnet produced the highest sound for low power drive as measured by the sound level meter when compared with the other two cones." @default.
