Drivers
One of the fundamental differences between these two speakers is that L82 Classic MKII is a 2-way design whereas the R3 Meta is a 3-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.

L82 Classic MKII features a 1" Titanium Dome Tweeter and 1 x 8" Pulp Woofer with a Crossover frequency at 1700Hz. On the other hand, the R3 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 1 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 420Hz and 2300Hz.
Frequency Response
L82 Classic MKII has a frequency range of 44-40k Hz whereas R3 Meta has a frequency range of 58-28k Hz. With a minimum frequency of 44Hz, the L82 Classic MKII can go significantly deeper on the low side and provide stronger bass compared to the R3 Meta's min frequency of 58Hz.
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
L82 Classic MKII is a 8 ohms speaker compared to the R3 Meta which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the R3 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. L82 Classic MKII sensitivity is rated at 88 dB and the R3 Meta's is rated at 87 dB. This 1 dB difference makes the JBL L82 Classic MKII a more sensitive speaker compared to KEF R3 Meta, 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.
L82 Classic MKII can handle a max power of 180 watts RMS from the amp the whereas L82 Classic MKII has a max power handling value of 150 watts RMS , 30 watts less than the R3 Meta.
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
Both L82 Classic MKII and R3 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.
JBL L82 Classic MKII's Five-way gold-plated binding posts terminals allows Bi-amping or bi-wiring
KEF R3 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
L82 Classic MKII has a front firing port whereas R3 Meta has a rear firing ports. JBL L82 Classic MKII's front-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF R3 Meta 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 JBL L82 Classic MKII's and KEF R3 Meta's external dimensions. JBL L82 Classic MKII has external dimensions of 472.8 x 281.0 x 315.5mm ( 18.6 x 11.0 x 12.4inch) whereas KEF R3 Meta has external dimensions of 423.0 x 202.0 x 337.0mm ( 16-5/8-inch x 7-15/16-inch x 13-1/4-inch) .
KEF R3 Meta is 79mm narrower and 49.8mm shorter than JBL L82 Classic MKII but it is also 21.5mm deeper.

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 L82 Classic MKII is approximately 886.6cm2 / 137.4inch2 and base area of the KEF R3 Meta is approximately 680.7cm2 / 105.5inch2. The L82 Classic MKII requires 30% more surface area than the R3 Meta which gives it a small disadvantage on placement in tight spaces.
