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
A130 is a 6 ohms speaker compared to the Bronze 1 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. A130 sensitivity is rated at 86 dB and the Bronze 1's is rated at 88 dB. This 2 dB difference makes the Monitor Audio Bronze 1 a more sensitive speaker compared to JBL A130, 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.
A130 can handle a max power of 125 watts RMS from the amp the whereas Bronze 1 has a max power handling value of 70 watts RMS, 55 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
A130 features Post type posts and Bronze 1 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both A130 and Bronze 1 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 A130's and Monitor Audio Bronze 1's external dimensions. 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) whereas Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm ( 10.2 x 6.4 x 8.0inch) .
JBL A130 is clearly the larger of the two speakers. Its body is 26mm wider, 63mm taller and 45mm deeper than Monitor Audio Bronze 1.
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 A130 is approximately 477.5cm2 / 74.0inch2 and base area of the Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2. The A130 requires 41% more surface area than the Bronze 1 which gives it a small disadvantage 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 A130 weighs 5.46kg / 12lbs and the Monitor Audio Bronze 1 weighs 3.50kg / 7.7lbs. This makes the A130 56% heavier than the Bronze 1.
Here is a comparison of how A130 and Bronze 1's weights compare with the average, max and min weights in Passive Bookshelf class.
