In this review, we will be comparing Ultra Center and HTM72 S2, two Passive Center Channel speakers from SVS and Bowers Wilkins. Let's have a brief look at the main features
of SVS Ultra Center and BW HTM72 S2 first before getting into our more
detailed comparison.
What size room are the SVS Ultra Center and BW HTM72 S2 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 Center and BW HTM72 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Ultra Center is a 3-way design whereas the HTM72 S2 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Ultra Center features a 1" aluminum Dome Tweeter , a 4" Midrange and 2 x 6.5" composite glass-fiber Woofer with a Crossover frequency at 500Hz and 2200Hz. On the other hand, the HTM72 S2 features a 1" Decoupled Carbon Dome Tweeter and 2 x 5" Continuum Woofer .
Frequency Response
Ultra Center has a frequency range of 45-32k Hz whereas HTM72 S2 has a frequency range of 70-28k Hz. With a minimum frequency of 45Hz, the Ultra Center can go significantly deeper on the low side and provide stronger bass compared to the HTM72 S2's min frequency of 70Hz.
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 Center Channel class in our database.

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 Center and HTM72 S2 have the same Impedance of 8 ohms and their sensitivity is also same at 87 dB.

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 Center can handle a max power of 225 watts RMS from the amp the whereas HTM72 S2 has a max power handling value of 120 watts RMS, 105 watts less than the Ultra Center.
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 Center and HTM72 S2 features dual binding post speaker terminals for bi-amping or bi-wiring.
SVS Ultra Center's 5-Way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Ultra Center and HTM72 S2 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Center's and BW HTM72 S2's external dimensions. SVS Ultra Center has external dimensions of 207.0 x 561.0 x 285.0mm ( 8-1/8 x 22-1/16 x 11-3/16inch) whereas BW HTM72 S2 has external dimensions of 169.0 x 482.0 x 278.0mm ( 6-5/8 x 18-15/16 x 10-15/16inch) .
SVS Ultra Center is clearly the larger of the two speakers. Its body is 79mm wider, 38mm taller and 7mm deeper than BW HTM72 S2.
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 Center is approximately 1598.9cm2 / 247.8inch2 and base area of the BW HTM72 S2 is approximately 1340.0cm2 / 207.7inch2. The Ultra Center requires 19% more surface area than the HTM72 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 Center weighs 14.09kg / 31lbs and the BW HTM72 S2 weighs 9.14kg / 20.1lbs. This makes the Ultra Center 54% heavier than the HTM72 S2.
Here is a comparison of how Ultra Center and HTM72 S2's weights compare with the average, max and min weights in Passive Center Channel class.
