Stage 250B features a 1" Hard-Dome Tweeter and 1 x 5.25" Polycellulose Woofer . On the other hand, the Stage 245C features a 1" Hard-Dome Tweeter and 4 x 4.5" Polycellulose Woofer .
Frequency Response
Stage 250B has a frequency range of 55-25k Hz whereas Stage 245C has a frequency range of 82-25k Hz. With a minimum frequency of 55Hz, the Stage 250B can go significantly deeper on the low side and provide stronger bass compared to the Stage 245C's min frequency of 82Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.
Low Frequency

High Frequency
Bookshelf Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Stage 250B and Stage 245C have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Stage 250B sensitivity is rated at 86 dB and the Stage 245C's is at 91 dB. This 5 dB difference makes the JBL Stage 245C a more sensitive speaker compared to JBL Stage 250B, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Stage 250B and Stage 245C has the same power range of 20-150 watts.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Stage 250B features 5-Way post type posts and Stage 245C has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Stage 250B and Stage 245C have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare JBL Stage 250B's and JBL Stage 245C's external dimensions. JBL Stage 250B has external dimensions of 321.0 x 202.0 x 242.0mm ( 12-5/8inch x 7-15/16inch x 9-1/2inch ) whereas JBL Stage 245C has external dimensions of 156.0 x 740.0 x 216.0mm ( 6-1/8 x 29-1/8 x 8-1/2 inch) .
JBL Stage 245C is 165mm shorter and 26mm less deeper than JBL Stage 250B but it is also 538mm wider.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the JBL Stage 250B is approximately 488.8cm2 / 75.8inch2 and base area of the JBL Stage 245C is approximately 1598.4cm2 / 247.8inch2. The Stage 250B requires 69% less surface area than the Stage 245C which gives it a small advantage on placement in tight spaces.
