In this review, we will be comparing Ultra Tower and Motion 40i, two Passive Floor-standing speakers from SVS and MartinLogan. Let's have a brief look at the main features
of SVS Ultra Tower and MartinLogan 40i first before getting into our more
detailed comparison.
What size room are the SVS Ultra Tower and MartinLogan 40i 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 SVS Ultra Tower and MartinLogan 40i compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 Motion 40i features a 1.0 x 1.4" Folded Motion Tweeter , a 5.5" Midrange and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 500Hz and 2600Hz.
Frequency Response
Ultra Tower has a frequency range of 28-32k Hz whereas Motion 40i has a frequency range of 40-25k 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 Motion 40i's min frequency of 40Hz.
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
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
Ultra Tower is a 8 ohms speaker compared to the Motion 40i 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 Motion 40i can provide this impedance level.
These two speakers also have different sensitivity levels. Ultra Tower sensitivity is rated at 88 dB and the Motion 40i's is rated at 92 dB. This 4 dB difference makes the MartinLogan 40i 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.
Ultra Tower and Motion 40i has the same power range of 20-300 watts.
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 Ultra Tower and Motion 40i features dual binding post speaker terminals for 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 SVS Ultra Tower's and MartinLogan 40i'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 MartinLogan 40i has external dimensions of 1055.0 x 193.0 x 332.0mm ( 41-1/2 x 7-9/16 x 13-1/16inch) .
SVS Ultra Tower is clearly the larger of the two speakers. Its body is 162mm wider, 104mm taller and 113mm deeper than MartinLogan 40i.
Below you can see the front view size comparison of SVS Ultra Tower and MartinLogan 40i 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 MartinLogan 40i is approximately 640.8cm2 / 99.3inch2. The Ultra Tower requires 147% more surface area than the Motion 40i 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 MartinLogan 40i weighs 20.40kg / 44.9lbs. This makes the Ultra Tower 68% heavier than the Motion 40i.
Here is a comparison of how Ultra Tower and Motion 40i's weights compare with the average, max and min weights in Passive Floor-standing class.
