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
Studio 620 and A130 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Studio 620 sensitivity is rated at 84 dB and the A130's is at 86 dB. This 2 dB difference makes the JBL A130 a more sensitive speaker compared to JBL Studio 620, 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.
Studio 620 can handle a max power of 125 watts RMS from the amp the whereas Studio 620 has a max power handling value of 100 watts RMS , 25 watts less than the A130.
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
Studio 620 features 5-way post type posts and A130 has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Studio 620 and A130 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 Studio 620's and JBL A130's external dimensions. JBL Studio 620 has external dimensions of 190 x 240 x 312mm ( 12.3 x 7-1/2inch x 9-1/2inch ) whereas JBL A130 has external dimensions of 323.0 x 191.0 x 250.0mm ( 12-11/16 x 7-1/2 x 9-13/16inch) .
JBL A130 is clearly the larger of the two speakers. Its body is 1mm wider, 11mm taller and 10mm deeper than JBL Studio 620.
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 Studio 620 is approximately 456.0cm2 / 70.7inch2 and base area of the JBL A130 is approximately 477.5cm2 / 74.0inch2. The Studio 620 requires 5% less surface area than the A130 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The JBL Studio 620 weighs 6.88kg / 15.1lbs and the JBL A130 weighs 5.46kg / 12lbs. This makes the Studio 620 26% heavier than the A130.
Here is a comparison of how Studio 620 and A130's weights compare with the average, max and min weights in Passive Bookshelf class.
