Low Frequency Audio Amplifier Using the LM386 : 6 …
https://www.instructables.com/low-frequency-audio-amplifier-using-the-LM386/
The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply . The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts. soo today i am going to show you how to make a low frequency audio amplifier using the LM386 .

THE DESIGN OF LOW-NOISE AUDIO-FREQUENCY AMPLIFIERS considering current ratios, without explicitly referring to the magnitudes of the voltages appearing at the amplifier input terminals. A great deal of confusion has arisen over the rela tion between noise figure and input resistance. It should be clear from Fig. 3 that if an amplifier has a

low frequency class-AB amplifier. Typically it provides 14 W output power (d = 0.5%) at 14 V/4 Ω. At ±14 V or 28 V, the guaranteed output power is 12 W on a 4 Ω load and 8 W on an 8 Ω (DIN45500). The TDA2030 provides high output current and has very low harmonic and crossover distortion. Furthermore, the device incorporates an original

It will lose sensitivity as you go down in frequency. If you want it to be flat down to 30 hz you need to add "EQ boost". To gain 3db, you need double the power. So you need 2^ 2 = 4 times as much power to add that 6db of power. The alternative is a high mass, high excursion low fs type of driver.
