S4700 and 4312G are members of JBL's Studio Monitor series of speakers. Below you can find the loudspeakers from this series.
What size room are the JBL S4700 and JBL 4312G 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:

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 S4700 and 4312G are 3-way speakers.

S4700 features a " Tweeter and 1 x 15" Pure Pulp Woofer with a Crossover frequency at 80Hz and 12000Hz. On the other hand, the 4312G features a 1" Magnesium/Aluminium Dome Tweeter, a 5" Midrange and 1 x 12" Pure Pulp Woofer with a Crossover frequency at 640Hz and 5000Hz.
Frequency Response
S4700 has a frequency range of 38-40k Hz whereas 4312G has a frequency range of 44-40k Hz. With a minimum frequency of 38Hz, the S4700 can go significantly deeper on the low side and provide stronger bass compared to the 4312G's min frequency of 44Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
S4700 and 4312G have the same Impedance of 6 ohms but where they differ is the sensitivity levels. S4700 sensitivity is rated at 94 dB and the 4312G's is at 90 dB. This 4 dB difference makes the JBL S4700 a more sensitive speaker compared to JBL 4312G, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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.
S4700 can handle a max power of 300 watts RMS, whereas 4312G has a max power handling value of 200 watts RMS, 100 watts less than the S4700.
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
Both S4700 and 4312G features dual binding post speaker terminals for bi-amping or 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 S4700's and JBL 4312G's external dimensions. JBL S4700 has external dimensions of 1068.0 x 500.0 x 371.0mm (42-1/16 x 19-11/16 x 14-5/8inch) whereas JBL 4312G has external dimensions of 597.0 x 362.0 x 305.0mm (23-1/2 x 14-1/4 x 12inch).
JBL S4700 is clearly the larger of the two speakers. Its body is 138mm wider, 471mm taller and 66mm deeper than JBL 4312G.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
JBL S4700 needs about 68% more floor or shelf area. JBL S4700 is 66mm deeper, so it stands that much further out from the wall. JBL S4700 is 471mm 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 S4700 is approximately 1855.0cm2 / 287.5inch2 and base area of the JBL 4312G is approximately 1104.1cm2 / 171.1inch2. The S4700 requires 68% more surface area than the 4312G which gives it a small disadvantage on placement in tight spaces.
