Here, it is a diagram of an Car audio active loudspeaker. The LF353 of, National Semiconductor. For Best Results using NE5532, is going to split audio signal into three bands (Active Filter). SANYO`S LA47536 is going to amplify these signals. In stereo mode, we shall have the action of eight high speakers who are going to create a very important

sound pressure. These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage (BI-FET II technology). They require low supply current yet maintain a large gain band width product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF353 is pin compatible with the standard LM1558 allowing designers to immediately upgrade e the overall performance of existing LM1558 and LM358 designs. These amplifiers may be used in applications such as high speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth. The devices also exhibit low noise and offset voltage drift. (National Semiconductor) I recommended using IC NE5532. The NE5532 is a dual high-performance low noise operational amplifier. Compared to most of the standard operational amplifiers, such as the LM1458, LM1558, or LM4558 it shows better noise performance, improved output drive capability and considerably higher small-signal and power bandwidths. This makes the device especially suitable for application in high quality and professional audio equipment, instrumentation and control circuits, and telephone channel amplifiers. The op amp is internally compensated for gains equal to one. If...
