Do you know if there is any literature that expands on this?
If you mean AES papers and the like, nothing comes to mind.
On Audioholics the guys are telling me that frequency response has little to do with the subjective qualities of bass "speed". It has more to do with room resonances and system Q.
I think I'm with Ethan on this. If you take the words at face value, the phrase bass speed
is like jumbo shrimp
in the sense that it means something if we agree on it, but as just words it doesn't work.
Bass speed is always 1100 feet per second, more or less depending on temperature, pressure and humidity. Therefore it doesn't compute.
If someone wanted to do something crazy like use terminology that was consistent with the traditional art of audio and could be taken af face value, they would talk about bass transient response
Now, we have a question that doesn't give one a headache just trying to understand it: Does bass transient response have more to do with frequency response or resonances?
I'm going to drop the reference to system Q because if you are familiar with with the traditional audio terminology as related to speakers, system Q can either relate to resonances or speaker directivity which are two vastly different things. In short the reference to system Q is either redundant or irrelevant! In either case clarity of communication is facilitated by dropping the reference to Q.
So now the question is: Does bass transient response have more to do with frequency response or resonances? The answer would be yes: Bass transient response has to do with both smooth frequency response and control over resonances.
Then there is a caveat. We could get extreme and look for good square wave response in the bass response, since that is a condition that relates to good transient response. This turns out to be too idealistic. Because of the nature of music which is probably best modeled as being a collection of tone bursts, good transient response for tone bursts is our most logical abstract criteria.
When I am listening to a sound system, one of my criteria is consistent level as a musician goes down the scale. I don't want notes popping in and out in that situation. That corresponds primarily to smooth frequency response.
