History
What size room are the JBL Stage 240H and JBL Stage 245C speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Stage 240H and Stage 245C are 2-way speakers.

Stage 240H features a 1" Hard-dome Tweeter and 1 x 4.5" 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 240H has a frequency range of 100-25k Hz whereas Stage 245C has a frequency range of 82-25k 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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Surround class in our database.
Low Frequency
Surround Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Stage 240H and Stage 245C have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Stage 240H sensitivity is rated at 85 dB and the Stage 245C's is at 91 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Stage 245C can handle a max power of 150 watts RMS, whereas Stage 240H has a max power handling value of 75 watts RMS, 75 watts less than the Stage 245C.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Stage 240H 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.
Physical Specs
The size of a speaker can sometimes be 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 240H's and JBL Stage 245C's external dimensions. 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) 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 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 240H is approximately 331.2cm2 / 51.3inch2 and base area of the JBL Stage 245C is approximately 1598.4cm2 / 247.8inch2. The Stage 240H requires 79% less surface area than the Stage 245C which gives it a small advantage on placement in tight spaces.
