R5 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2700Hz. On the other hand, the Ultra Tower features a 1.0" aluminum Dome Tweeter , a 6.5" Midrange and 2 x 8.0" Polypropylene Woofer with a Crossover frequency at 160HZ and 2000Hz.
Frequency Response
R5 Meta has a frequency range of 52-28k Hz whereas Ultra Tower has a frequency range of 28-32k Hz. With a minimum frequency of 28Hz, the Ultra Tower can go significantly deeper on the low side and provide stronger bass compared to the R5 Meta's min frequency of 52Hz.
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 Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
High Frequency
Floor-standing 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
R5 Meta is a 4 ohms speaker compared to the Ultra Tower 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 R5 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R5 Meta sensitivity is rated at 87 dB and the Ultra Tower's is rated at 88 dB. This 1 dB difference makes the SVS Ultra Tower a more sensitive speaker compared to KEF R5 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.
R5 Meta can handle a max power of 300 watts RMS from the amp the whereas R5 Meta has a max power handling value of 200 watts RMS , 100 watts less than the Ultra Tower.
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 R5 Meta and Ultra Tower features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R5 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
SVS Ultra Tower's Binding 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 R5 Meta's and SVS Ultra Tower's external dimensions. KEF R5 Meta has external dimensions of 1074.0 x 274.0 x 343.0mm ( 42-1/4-inch x 10-3/4-inch x 13-1/2-inch) whereas SVS Ultra Tower has external dimensions of 1159.0 x 355.0 x 445.0mm ( 45-5/8 x 13-15/16 x 17-1/2inch) .
SVS Ultra Tower is clearly the larger of the two speakers. Its body is 81mm wider, 85mm taller and 102mm deeper than KEF R5 Meta.
Below you can see the front view size comparison of KEF R5 Meta and SVS Ultra Tower in scale.

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 R5 Meta is approximately 939.8cm2 / 145.7inch2 and base area of the SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2. The R5 Meta requires 41% less surface area than the Ultra Tower which gives it a small advantage on placement in tight spaces.
