audioguru, you're still deliberately misstating the reality to the detriment of anyone wanting to learn anything about audio
I am not misstating anything!
Reality is that deep bass sounds are produced by a pretty big woofer, not from these tiny little things.
All half-decent speakers have a frequency response spec'd at plus and minus 3dB (double the power or half the power) which most people can hear as a small change in level.
Cheap speakers spec the frequency response at plus and minus 10dB or 20 dB which is horrible because then the response is all over the place. No bass and very loud treble or no treble and loud boomy bass. Maybe no bass and no treble but a very loud midrange. Maybe no midrange but but very loud bass and treble.
Very poor speakers do not state how many dBs their response is off. This Chinese speaker with the tiny drivers does not say how many dBs it is off.
A 15" or 18" high quality woofer produces bass frequencies down to 20Hz or 25Hz at -3dB.
A 12" high quality woofer produces bass frequencies down to about 25Hz or 30Hz at -3db.
A 10" woofer produces bass frequencies down to about 30Hz or 40Hz at -3dB.
An 8" woofer produces bass frequencies down to about 50Hz at -3dB.
A 5" woofer produces bass frequencies down to about 80Hz at -3dB.
A 4" woofer produces bass frequencies down to about 100Hz at -3dB. No deep bass.
A 3" very high quality speaker produces bass frequencies down to about 150Hz at -3dB. No deep bass.
A tiny high quality 2.5" midrange speaker produces frequencies down to about 200Hz at -3dB. No bass.
It is a small, fairly inexpensive computer speaker system, not a hi-fi speaker system.
