Real loudspeakers show flat magnitude response only below 800 Hz with a midrange dip
Evidence
The magnitude response of the loudspeaker is relatively flat under 800 Hz, and at frequencies between 1 kHz and 10 kHz, a clear dip is seen in the response. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 505
