Hi guys,
Just a question regarding light/heavy cones, for low bass frequencies one does not need light cones with low mass as it pertains to "speed" as light = high resonant frequency, which for low bass frequencies I would imagine is not particularly relevant.
Correct me if I'm wrong.

What I'm gathering is that huge power and light mass = no requirement for deep bass response. Perhap higher up in the frequency range, but down low it's not relevant. So much reading to do ... 🙁
Does this make any sense : The accuracy of the conversion of the electrical input signal to the mechanical waveform has everything to do with the responsiveness of the cone (in a perfect system) and this is all time domain function? I read that somewhere but it doesn't make sense to me.

I wouldn't mix electrical (acoustical)= ability to produce deep bass response(BW) with mechanical quantities (besides large cone-area/ small and low x-max versus high), here responsiveness= u/f connected to wishful thinking of 'requirements' or ' 'accuracy' of speaker driver in terms of on how faithful it would be depending on the driver cone mass and the supplied power (Power source translates into a Force=BIL= ma).
A mechanical element that dissipates power have to do that with friction.
There are at least two different involved in a speaker driver besides the mechanical to acoustical losses resulting in a wave(a loss) that we hear as BW:
Dry friction that is independent of velocity, i.e. mechanical resistance = f/u and viscous friction that occurs in the cone surrounds,the spider and the cone surround where a ever changing velocity differential exists thus depends on the velocity.
Whats make sound is the acceleration of the cone not whatever the mechanical velocity is.
A driver can produce equal deep frequencies at very low or of course at high mechanical velocity's.
The only requirements are that the velocity change = Acceleration are equal too.
Compare the mechanical velocity's involved in a 'Ear-piece of a head phone to a 18” deep digging high x-max Speaker driver.
Both can produce very low frequencies albeit using very different cone velocities.
