Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the AE520 and SVS Ultra Tower compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

AE520 features a 1" carbon fibre dome with waveguide Tweeter , a 5.2" Midrange and 4 x 5" carbon fibre cone Woofer with a Crossover frequency at 373Hz and 2.8kHz. 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
AE520 has a frequency range of 30Hz - 28kHz whereas Ultra Tower has a frequency range of 28-32k Hz. With a minimum frequency of 28Hz, the Ultra Tower can go slightly deeper then the AE520's min frequency of 30Hz.
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.

High Frequency

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
AE520 is a 6 ohms speaker compared to the Ultra Tower which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AE520 sensitivity is rated at 90 dB and the Ultra Tower's is rated at 88 dB. This 2 dB difference makes the AE520 a more sensitive speaker compared to SVS Ultra Tower, 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.
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.
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 AE520's and SVS Ultra Tower's external dimensions. AE520 has external dimensions of 1130.0 x 185.0 x 320.0mm ( 44.5 x 7.3 x 12.6inch) 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 170mm wider, 29mm taller and 125mm deeper than AE520.
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 AE520 is approximately 592.0cm2 / 91.8inch2 and base area of the SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2. The AE520 requires 63% less surface area than the Ultra Tower which gives it a small advantage on placement in tight spaces.
