In this review, we will be comparing R3 Meta and BRX, two Passive Bookshelf speakers from KEF and GoldenEar. Let's have a brief look at the main features
of KEF R3 Meta and GoldenEar BRX first before getting into our more
detailed comparison.
What size room are the KEF R3 Meta and GoldenEar BRX 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 KEF R3 Meta and GoldenEar BRX compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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

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. On the other hand, the BRX features a " Folded Ribbon Tweeter and 1 x 6" Polypropylene Woofer .
Frequency Response
R3 Meta has a frequency range of 58-28k Hz whereas BRX has a frequency range of 40-35k Hz. With a minimum frequency of 40Hz, the BRX 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.

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
R3 Meta is a 4 ohms speaker compared to the BRX which has a nominal impedance of 8 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. R3 Meta sensitivity is rated at 87 dB and the BRX's is rated at 90 dB. This 3 dB difference makes the GoldenEar BRX 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.
R3 Meta can handle a max power of 250 watts RMS from the amp the whereas R3 Meta has a max power handling value of 180 watts RMS , 70 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
R3 Meta features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. BRX has a 5-way post which doesn't feature bi-amping/bi-wiring.

GoldenEar BRX's 5-way post terminals
Cabinet Type and Port Position
Both R3 Meta and BRX 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 KEF R3 Meta's and GoldenEar BRX's external dimensions. 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) whereas 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) .
GoldenEar BRX is 115mm shorter and 24mm less deeper than KEF R3 Meta but it is also 5mm wider.
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 R3 Meta is approximately 680.7cm2 / 105.5inch2 and base area of the GoldenEar BRX is approximately 647.9cm2 / 100.4inch2. The R3 Meta requires 5% more surface area than the BRX 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 KEF R3 Meta weighs 12.41kg / 27.3lbs and the GoldenEar BRX weighs 5.45kg / 12lbs. This makes the R3 Meta 128% heavier than the BRX.
Here is a comparison of how R3 Meta and BRX's weights compare with the average, max and min weights in Passive Bookshelf class.
