In this review, we will be comparing two different type of speakers by JBL. JBL Stage 280F is a Floor-standing speaker whereas the A120 is a Bookshelf speaker.
Let's have a brief look at the main features
of JBL Stage 280F and JBL A120 first before getting into our more
detailed comparison.
What size room are the JBL Stage 280F and JBL A120 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:
In the following sections, we will get into more detail in order to better understand how the JBL Stage 280F and JBL A120 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Stage 280F is a 3-way design whereas the A120 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Stage 280F features a 1" Hard-Dome Tweeter and 2 x 8" Polycellulose Woofer . On the other hand, the A120 features a 1" aluminum Hard-Dome Tweeter and 1 x 4.5" Polycellulose Woofer .
Frequency Response
Stage 280F has a frequency range of 39-25k Hz whereas A120 has a frequency range of 60-40k Hz. With a minimum frequency of 39Hz, the Stage 280F can go significantly deeper on the low side and provide stronger bass compared to the A120's min frequency of 60Hz.
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 Floor-standing 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 280F and A120 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Stage 280F sensitivity is rated at 91 dB and the A120's is at 86 dB. This 5 dB difference makes the JBL Stage 280F a more sensitive speaker compared to JBL A120, 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 280F can handle a max power of 225 watts RMS from the amp the whereas A120 has a max power handling value of 125 watts RMS, 100 watts less than the Stage 280F.
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 280F features 5-way post type posts and A120 has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Stage 280F and A120 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 280F's and JBL A120's external dimensions. JBL Stage 280F has external dimensions of 1113.0 x 359.0 x 420.0mm ( 43-13/16inch x 14-1/8inch x 16-1/2inch ) whereas JBL A120 has external dimensions of 286.0 x 172.0 x 189.0mm ( 11-1/4 x 6-3/4 x 7-7/16inch) .
JBL Stage 280F is clearly the larger of the two speakers. Its body is 187mm wider, 827mm taller and 231mm deeper than JBL A120.
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 280F is approximately 1507.8cm2 / 233.7inch2 and base area of the JBL A120 is approximately 325.1cm2 / 50.4inch2. The Stage 280F requires 364% more surface area than the A120 which gives it a small disadvantage on placement in tight spaces.
