Compare JBL Stage2 624 and Stage1 621
The models JBL Stage2 624 and JBL Stage1 621 are coaxial car speakers measuring 6.5" (16.5 cm) and have the same frequency range from 55 to 20000 Hz. However, the Stage2 624 has a higher nominal power of 40 W and a maximum power of 240 W (Peak), while the Stage1 621 has a nominal power of 35 W and a maximum power of 175 W (Peak). The sensitivity of Stage2 624 is 91 dB, which is 1 dB higher than that of Stage1 621 with 90 dB. Both speakers have the same size and impedance of 4 Ohms, but Stage2 624 offers slightly higher performance.

Glossary
Rated power
Rated power of the acoustic system. Most often, the average (root mean square) sound power is indicated as rated.
The most obvious point related to this characteristic is the volume of sound: the more powerful the sound system, the louder the sound it can produce, all other things being equal. In addition, compatibility with an external amplifier depends on this indicator: its power should not exceed the power of the sound system, otherwise overloads and damage to the speakers are possible.

Max. power
The maximum power of a short-term (up to several seconds) incoming signal that the speaker can withstand without physical damage. Just like the nominal power, it matters for the selection of acoustics for an amplifier (or vice versa): it is believed that the maximum power of the speakers should be at least 2 times higher than the maximum power of the signal source.
Sensitivity
This parameter determines the volume of the sound of a particular speaker when a certain standard signal is fed to it. Typically, this is considered a 1 W signal with a frequency of 1000 Hz. The higher the sensitivity, the less the speaker is demanding on the power of the amplifier. So, it is believed that for acoustics connected directly to the car radio, the sensitivity should be 80 dB or more; for less sensitive systems it is recommended to use a separate amplifier.
