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. On the other hand, the Evoke 50 features a 1.1" Tweeter, a 5.5" Midrange and 2 x 7" Magnesium Silicate Polymer Woofer with a Crossover frequency at 430Hz and 3500Hz.
Frequency Response
Ultra Tower has a frequency range of 28-32k Hz whereas Evoke 50 has a frequency range of 35-23k 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 Evoke 50's min frequency of 35Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Ultra Tower is a 8 ohms speaker compared to the Evoke 50 which has a nominal impedance of 4 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 Evoke 50 can provide this impedance level.
These two speakers also have different sensitivity levels. Ultra Tower sensitivity is rated at 88 dB and the Evoke 50's is rated at 87 dB. This 1 dB difference makes the SVS Ultra Tower a more sensitive speaker compared to Dynaudio Evoke 50, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Ultra Tower can handle a max power of 300 watts RMS, whereas Evoke 50 has a max power handling value of 260 watts RMS, 40 watts less than the Ultra Tower.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Ultra Tower features Binding post posts which make bi-amping or bi-wiring possible. Evoke 50 has a Binding post which doesn't feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare SVS Ultra Tower's and Dynaudio Evoke 50's external dimensions. 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) whereas Dynaudio Evoke 50 has external dimensions of 1162.0 x 305.0 x 373.0mm (45-7/8 x 12-1/16 x 14-3/4inch).
Dynaudio Evoke 50 is 50mm narrower and 72mm less deeper than SVS Ultra Tower but it is also 3mm taller.

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 SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2 and base area of the Dynaudio Evoke 50 is approximately 1137.7cm2 / 176.3inch2. The Ultra Tower requires 39% more surface area than the Evoke 50 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 SVS Ultra Tower weighs 34.27kg / 75.4lbs and the Dynaudio Evoke 50 weighs 26.90kg / 59.2lbs. This makes the Ultra Tower 27% heavier than the Evoke 50.

These sit in different price classes - Dynaudio Evoke 50 costs roughly 1.9x what SVS Ultra Tower does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | A | SVS Ultra Tower digs deeper - 28Hz against 35Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 87dB) - both want much the same power. |
| Amplifier match | A | SVS Ultra Tower is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 260W). |
| Size | depends | Dynaudio Evoke 50 is easier to place; SVS Ultra Tower is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | SVS Ultra Tower: bi-amping. |
| Price | A | SVS Ultra Tower is cheaper - $2,600 against $5,000, about 48% less; arguably a different class. |
A SVS Ultra Tower B Dynaudio Evoke 50
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS Ultra Tower is the easier recommendation: it leads on most of the measured areas and costs less. Take Dynaudio Evoke 50 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 35Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, SVS Ultra Tower is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
