In this review, we will be comparing Diamond 225 and A130, two Passive Bookshelf speakers from Wharfedale and JBL. Let's have a brief look at the main features
of Wharfedale 225 and JBL A130 first before getting into our more
detailed comparison.
What size room are the Wharfedale 225 and JBL A130 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 Wharfedale 225 and JBL A130 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz. On the other hand, the A130 features a 1" aluminum Hard-Dome Tweeter and 1 x 5.25" Polycellulose Woofer .
Frequency Response
Diamond 225 has a frequency range of 45-20k Hz whereas A130 has a frequency range of 55-40k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go significantly deeper on the low side and provide stronger bass compared to the A130's min frequency of 55Hz.
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 Bookshelf 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
Diamond 225 is a 8 ohms speaker compared to the A130 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Diamond 225 sensitivity is rated at 87 dB and the A130's is rated at 86 dB. This 1 dB difference makes the Wharfedale 225 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.
Diamond 225 can handle a max power of 125 watts RMS from the amp the whereas Diamond 225 has a max power handling value of 120 watts RMS , 5 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
Diamond 225 features Post posts which make bi-amping or bi-wiring possible. A130 has a 5-way post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Diamond 225 has a bottom firing port whereas A130 has a rear firing ports. Wharfedale 225's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to JBL A130 with its rear-firing port.
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 Wharfedale 225's and JBL A130's external dimensions. Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) 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) .
Wharfedale 225 is clearly the larger of the two speakers. Its body is 5mm wider, 32mm taller and 40mm deeper than JBL A130.
Below you can see the front view size comparison of Wharfedale 225 and JBL A130 in scale.
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 Wharfedale 225 is approximately 568.4cm2 / 88.1inch2 and base area of the JBL A130 is approximately 477.5cm2 / 74.0inch2. The Diamond 225 requires 19% more surface area than the A130 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 Wharfedale 225 weighs 6.55kg / 14.4lbs and the JBL A130 weighs 5.46kg / 12lbs. This makes the Diamond 225 20% heavier than the A130.
Here is a comparison of how Diamond 225 and A130's weights compare with the average, max and min weights in Passive Bookshelf class.
