Importance of slew rate and transient response

[AllenB]

The causes for attenuated transients are many, but one of them is the motor not being able to do its job fast enough (slippage, post 58). Most often this accounts for only a small amount. Quanti/qualifying it is my aim

What if there were no appreciable mass attached to this motor, what would you see happening?

What do you mean by radiation impedance? Resistance of air to diaphragm movement?

Yes. It's low at low frequency and rises with it. Actually the reason why anything moving in a gas or a liquid is producing what we perceive as sound. Here a good explanation can be found. I discovered this recently, it's a nice roundup of what you otherwise would have to extract from standard acoustics text books.

I've had a massive headache for the last couple days (and still have it)

That sucks. Hope you'll get well soon.
