In this review, we will be comparing R2 Meta and Ultra Center, two Passive Center Channel speakers from KEF and SVS. Let's have a brief look at the main features
of KEF R2 Meta and SVS Ultra Center first before getting into our more
detailed comparison.
What size room are the KEF R2 Meta and SVS Ultra Center 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 R2 Meta and SVS Ultra Center compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R2 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 560Hz and 2500Hz. On the other hand, the Ultra Center features a 1" aluminum Dome Tweeter , a 4" Midrange and 2 x 6.5" composite glass-fiber Woofer with a Crossover frequency at 500Hz and 2200Hz.
Frequency Response
R2 Meta has a frequency range of 67-28k Hz whereas Ultra Center has a frequency range of 45-32k Hz. With a minimum frequency of 45Hz, the Ultra Center can go significantly deeper on the low side and provide stronger bass compared to the R2 Meta's min frequency of 67Hz.
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.
Low Frequency

High Frequency
Center Channel 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
R2 Meta is a 4 ohms speaker compared to the Ultra Center 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 R2 Meta can provide this impedance level.
On the other hand, they have the same sensitivity of 87 dBdB.

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.
R2 Meta can handle a max power of 225 watts RMS from the amp the whereas R2 Meta has a max power handling value of 200 watts RMS , 25 watts less than the Ultra Center.
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 R2 Meta and Ultra Center features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R2 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
SVS Ultra Center's 5-Way post terminals allows Bi-amping or 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 KEF R2 Meta's and SVS Ultra Center's external dimensions. KEF R2 Meta has external dimensions of 177.0 x 553.0 x 312.0mm ( 6-15/16-inch x 21-3/4-inch x 12-1/4-inch) whereas SVS Ultra Center has external dimensions of 207.0 x 561.0 x 285.0mm ( 8-1/8 x 22-1/16 x 11-3/16inch) .
KEF R2 Meta is 8mm narrower and 30mm shorter than SVS Ultra Center but it is also 27mm 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 R2 Meta is approximately 1725.4cm2 / 267.4inch2 and base area of the SVS Ultra Center is approximately 1598.9cm2 / 247.8inch2. The R2 Meta requires 8% more surface area than the Ultra Center 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 R2 Meta weighs 15.45kg / 34lbs and the SVS Ultra Center weighs 14.09kg / 31lbs. This makes the R2 Meta 10% heavier than the Ultra Center.
Here is a comparison of how R2 Meta and Ultra Center's weights compare with the average, max and min weights in Passive Center Channel class.
