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 703 S2 features a 1" Tweeter, a 6" Midrange and 2 x 6.5" Aerofoil Woofer.
Frequency Response
Ultra Tower has a frequency range of 28-32k Hz whereas 703 S2 has a frequency range of 46-28k 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 703 S2's min frequency of 46Hz.
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 and 703 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Ultra Tower sensitivity is rated at 88 dB and the 703 S2's is at 89 dB. This 1 dB difference makes the B&W 703 S2 a more sensitive speaker compared to SVS Ultra Tower, 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 703 S2 has a max power handling value of 200 watts RMS, 100 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.

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
Both Ultra Tower and 703 S2 features dual binding post speaker terminals for bi-amping or 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 B&W 703 S2'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 B&W 703 S2 has external dimensions of 1025 x 200 x 321 mm (40.4 x 7-7/8 x 12.6 inch).
SVS Ultra Tower is clearly the larger of the two speakers. Its body is 155mm wider, 134mm taller and 124mm deeper than B&W 703 S2.
Below you can see the front view size comparison of SVS Ultra Tower and B&W 703 S2 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 SVS Ultra Tower is approximately 1579.8cm2 / 244.9inch2 and base area of the B&W 703 S2 is approximately 642.0cm2 / 99.5inch2. The Ultra Tower requires 146% more surface area than the 703 S2 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 B&W 703 S2 weighs 25.00kg / 55lbs. This makes the Ultra Tower 37% heavier than the 703 S2.
Here is a comparison of how Ultra Tower and 703 S2's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - B&W 703 S2 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 46Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 89dB) - both want much the same power. |
| Headroom | A | SVS Ultra Tower takes more power (300W vs 200W) - more in hand in a big room. |
| Size | depends | B&W 703 S2 is easier to place; SVS Ultra Tower is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | SVS Ultra Tower: bi-amping; B&W 703 S2: bi-amping. B&W 703 S2 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | SVS Ultra Tower is cheaper - $2,600 against $5,000, about 48% less; arguably a different class. |
A SVS Ultra Tower B B&W 703 S2
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 B&W 703 S2 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 46Hz anyway, so judge these on the other rows instead. Match it to your room: we rate SVS Ultra Tower the better fit for a very large room, and B&W 703 S2 for a mid-size room.
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.
