Yes.It has no that detail.Its starting frequency is 40Khz.Your Sony speakers have no detailed specs. It says the "effective" frequency range without saying if it is +/- 2dB or if it is +/- 40dB.

Good look finding a speaker with that incredible specification40kHz is not audio, instead it is an ultrasonic frequency that some dogs might hear. The 6.75" woofer might produce a very faint 40Hz.
A speaker specification should say +/- 2dB from 20Hz to 20kHz.
You're still providing little boost, and at frequencies well below what the tiny speaker can reproduce.Ok thanks.I'm going to finish with these settings. just have a look.
You two are correct.The boost is un-noticable.I am repeatedly changing values and make checking...Your new boost of only 4.2dB for 40Hz is barely noticeable and only 2dB for highs is not noticeable.
Your 220nF C2 feeding the 27k R3 resistor cuts 27Hz at 3dB.
Excellent explanation. Everything is clear. ThanksWell if P=(V^2)/R, then P*R = V^2; so V=sqrt(P*R); V=sqrt(8*4); V=sqrt(32)
You got it. I also doubt on that.Not sure where the 8 ohms = 4 ohms bridged comes from.
As far as loading on the amp goes, each half of the amp effectively feeds half of the speaker - so with an 8 ohm speaker each amp is feeding 4 ohms.Not sure where the 8 ohms = 4 ohms bridged comes from.
