In this review, we will be comparing Revel Concerta2 C25 and Ultra Center, two Passive Center Channel speakers from Revel and SVS. Let's have a brief look at the main features
of Revel Concerta2 C25 and SVS Ultra Center first before getting into our more
detailed comparison.
What size room are the Revel Concerta2 C25 and SVS Ultra Center 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 Revel Concerta2 C25 and SVS Ultra Center 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 Revel Concerta2 C25 is a 2-way design whereas the Ultra Center is a 3-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.

Revel Concerta2 C25 features a 1" aluminum dome with proprietary acoustic lens and waveguide Tweeter and 2 x 5.25" anodized aluminum cone Woofer . On the other hand, the 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.
Frequency Response
Revel Concerta2 C25 has a frequency range of 80Hz- 20kHz whereas Ultra Center has a frequency range of 45-32k 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 Revel Concerta2 C25's min frequency of 80Hz.
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.

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.
Revel Concerta2 C25 can handle a max power of 225 watts RMS from the amp the whereas Revel Concerta2 C25 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
Ultra Center features 5-Way post posts which make bi-amping or bi-wiring possible. Revel Concerta2 C25 has a 5-Way post which doesn't feature bi-amping/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 Revel Concerta2 C25's and SVS Ultra Center's external dimensions. Revel Concerta2 C25 has external dimensions of 188.0 x 496.0 x 259.0mm ( 7-3/8 x 19-1/2 x 10-3/16inch) whereas 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) .
SVS Ultra Center is clearly the larger of the two speakers. Its body is 65mm wider, 19mm taller and 26mm deeper than Revel Concerta2 C25.
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 Revel Concerta2 C25 is approximately 1284.6cm2 / 199.1inch2 and base area of the SVS Ultra Center is approximately 1598.9cm2 / 247.8inch2. The Revel Concerta2 C25 requires 20% less surface area than the Ultra Center which gives it a small advantage 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 Revel Concerta2 C25 weighs 9.09kg / 20lbs and the SVS Ultra Center weighs 14.09kg / 31lbs. This makes the Ultra Center 55% heavier than the Revel Concerta2 C25.
Here is a comparison of how Revel Concerta2 C25 and Ultra Center's weights compare with the average, max and min weights in Passive Center Channel class.
