Is that the same as the melody range? Defined per this discussion:

Where is the fundamental range in relation to the melody range? Low C is 128 Hz. and it seems to me low C is in the melody range. I guess I think of the melody range from 100 - 400... is this where you place the fundamental channel?

It is not well defined and I do not think that a specific definition is ever necessary. What is the difference how one or another channel is related to melody range? Melody range is definition of Sound, the layout of the drivers is absolutely irrelevant from it and wary from given characteristic of driver, horn, crossover and loading pattern. So, I feel that the question is very much irrelevant.

Saying it I also disagree with Zako that for sound reproduction the musical definition of melody range is valuable.   In music theory the melody range defined as 10 tones up from middle C. However, we do not have universal middle C. The middle for a flute and for bass clarinet would be very different. Then we do not deal with live sound but with sound reproduction by artificial means and therefore, in my view, the melody range for playback shall include second harmonic.

If we pretend that middle C for whole orchestra would be at 262Hz then the melody range for playback I would defend as from 120Hz to 500-700Hz. The point is, however, that there is no point to define it firmly for a playback and there is absolutely no reason to think about melody range when we try to assess drivers. I understand that somebody would like to talk about melody ranges but let to keep this thread dedicated to JBL 2490 driver.
