In this review, we will be comparing GoldenEar SuperCenter XL and R2c, two Center Channel speakers from GoldenEar and KEF. Let's have a brief look at the main features
of GoldenEar SuperCenter XL and KEF R2c first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the GoldenEar SuperCenter XL and KEF R2c 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 GoldenEar SuperCenter XL is a -way design whereas the R2c 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.

GoldenEar SuperCenter XL features a " Tweeter and x " Woofer . On the other hand, the R2c features a 1" aluminum Dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
GoldenEar SuperCenter XL has a frequency range of 36-35k Hz whereas R2c has a frequency range of 74-28k Hz. With a minimum frequency of 36Hz, the GoldenEar SuperCenter XL can go significantly deeper on the low side and provide stronger bass compared to the R2c's min frequency of 74Hz.
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 Center Channel 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
GoldenEar SuperCenter XL and R2c have the same Impedance of 8 ohms but where they differ is the sensitivity levels. GoldenEar SuperCenter XL sensitivity is rated at 91 dB and the R2c's is at 87 dB. This 4 dB difference makes the GoldenEar SuperCenter XL a more sensitive speaker compared to KEF R2c, 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.
GoldenEar SuperCenter XL can handle a max power of 250 watts RMS from the amp the whereas R2c has a max power handling value of 200 watts RMS, 50 watts less than the GoldenEar SuperCenter XL.
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
R2c features Binding post posts which make bi-amping or bi-wiring possible. GoldenEar SuperCenter XL has a 5-Way post which doesn't feature bi-amping/bi-wiring.
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 SuperCenter XL's and KEF R2c's external dimensions. GoldenEar SuperCenter XL has external dimensions of 147.0 x 737.0 x 283.0mm ( 5-3/4 x 29 x 11-1/8inch) whereas KEF R2c has external dimensions of 177.0 x 551.0 x 316.0mm ( 6-15/16 x 21-11/16 x 12-7/16inch) .
GoldenEar SuperCenter XL is 30mm shorter and 33mm less deeper than KEF R2c but it is also 186mm 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 GoldenEar SuperCenter XL is approximately 2085.7cm2 / 323.3inch2 and base area of the KEF R2c is approximately 1741.2cm2 / 269.9inch2. The GoldenEar SuperCenter XL requires 20% more surface area than the R2c 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 GoldenEar SuperCenter XL weighs 9.55kg / 21lbs and the KEF R2c weighs 16.90kg / 37.2lbs. This makes the R2c 77% heavier than the GoldenEar SuperCenter XL.
Here is a comparison of how GoldenEar SuperCenter XL and R2c's weights compare with the average, max and min weights in Passive Center Channel class.
