Stage 245C features a 1" Hard-Dome Tweeter and 4 x 4.5" Polycellulose Woofer . On the other hand, the Stage 240H features a 1" Hard-dome Tweeter and 1 x 4.5" Polycellulose Woofer .
Frequency Response
Stage 245C has a frequency range of 82-25k Hz whereas Stage 240H has a frequency range of 100-25k Hz. With a minimum frequency of 82Hz, the Stage 245C can go significantly deeper on the low side and provide stronger bass compared to the Stage 240H's min frequency of 100Hz.
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 Center Channel class in our database.

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 245C and Stage 240H have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Stage 245C sensitivity is rated at 91 dB and the Stage 240H's is at 85 dB. This 6 dB difference makes the JBL Stage 245C a more sensitive speaker compared to JBL Stage 240H, 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 245C can handle a max power of 150 watts RMS from the amp the whereas Stage 240H has a max power handling value of 75 watts RMS, 75 watts less than the Stage 245C.
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 245C features 5-Way post type posts and Stage 240H has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
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 245C's and JBL Stage 240H's external dimensions. 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) whereas JBL Stage 240H has external dimensions of 272.0 x 181.0 x 183.0mm ( 10-11/16 x 7-1/8 x 7-3/16 inch) .
JBL Stage 240H is 559mm narrower and 33mm less deeper than JBL Stage 245C but it is also 116mm taller.
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 245C is approximately 1598.4cm2 / 247.8inch2 and base area of the JBL Stage 240H is approximately 331.2cm2 / 51.3inch2. The Stage 245C requires 383% more surface area than the Stage 240H which gives it a small disadvantage on placement in tight spaces.
