Reference 1 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 1 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz. On the other hand, the L100 Classic features a 1" Titanium Dome Tweeter , a 5.25" Midrange and 1 x 12" Pulp Woofer with a Crossover frequency at 450Hz and 3500Hz.
Frequency Response
Reference 1 Meta has a frequency range of 45-35k Hz whereas L100 Classic has a frequency range of 40-40k Hz. With a minimum frequency of 40Hz, the L100 Classic can go significantly deeper on the low side and provide stronger bass compared to the Reference 1 Meta's min frequency of 45Hz.
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.

High Frequency
Bookshelf Speakers
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
Reference 1 Meta and L100 Classic have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Reference 1 Meta sensitivity is rated at 85 dB and the L100 Classic's is at 90 dB. This 5 dB difference makes the JBL L100 Classic a more sensitive speaker compared to KEF Reference 1 Meta, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Reference 1 Meta and the Reference 1 Meta can provide this impedance level.

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.
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
Reference 1 Meta features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. L100 Classic has a Five-way gold-plated binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Reference 1 Meta has a rear firing port whereas L100 Classic has a front firing ports. JBL L100 Classic's front-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF Reference 1 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 KEF Reference 1 Meta's and JBL L100 Classic's external dimensions. KEF Reference 1 Meta has external dimensions of 440 x 205 x 422 mm ( 17.3 x 8.1 x 16.6 ) whereas JBL L100 Classic has external dimensions of 636.5 x 389.6 x 371.5mm ( 25.0 x 15.3 x 14.6inch) .
KEF Reference 1 Meta is 184.6mm narrower and 196.5mm shorter than JBL L100 Classic but it is also 50.5mm 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 KEF Reference 1 Meta is approximately 865.1cm2 / 134.1inch2 and base area of the JBL L100 Classic is approximately 1447.4cm2 / 224.3inch2. The Reference 1 Meta requires 40% less surface area than the L100 Classic which gives it a small advantage on placement in tight spaces.
