BRX features a " Folded Ribbon Tweeter and 1 x 6" Polypropylene Woofer . On the other hand, the LS50 Meta features a 1" Aluminum Hard-Dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2100Hz.
Frequency Response
BRX has a frequency range of 40-35k Hz whereas LS50 Meta has a frequency range of 79-28k Hz. With a minimum frequency of 40Hz, the BRX can go significantly deeper on the low side and provide stronger bass compared to the LS50 Meta's min frequency of 79Hz.
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
BRX and LS50 Meta have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BRX sensitivity is rated at 90 dB and the LS50 Meta's is at 85 dB. This 5 dB difference makes the GoldenEar BRX a more sensitive speaker compared to KEF LS50 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.
BRX can handle a max power of 250 watts RMS from the amp the whereas LS50 Meta has a max power handling value of 100 watts RMS, 150 watts less than the BRX.
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
BRX features Post type posts and LS50 Meta has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both BRX and LS50 Meta 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 GoldenEar BRX's and KEF LS50 Meta's external dimensions. GoldenEar BRX has external dimensions of 308.0 x 207.0 x 313.0mm ( 12-1/8 x 8-1/8 x 12-5/16inch) whereas KEF LS50 Meta has external dimensions of 303.0 x 201.0 x 281.0mm ( 11-15/16 x 7.875 x 11-1/16inch) .
GoldenEar BRX is clearly the larger of the two speakers. Its body is 6mm wider, 5mm taller and 32mm deeper than KEF LS50 Meta.
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 GoldenEar BRX is approximately 647.9cm2 / 100.4inch2 and base area of the KEF LS50 Meta is approximately 564.8cm2 / 87.5inch2. The BRX requires 15% more surface area than the LS50 Meta which gives it a small disadvantage on placement in tight spaces.
