In this review, we will be comparing RP-600C and Ultra Center, two Passive Center Channel speakers from Klipsch and SVS. Let's have a brief look at the main features
of Klipsch RP-600C and SVS Ultra Center first before getting into our more
detailed comparison.
What size room are the Klipsch RP-600C 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 Klipsch RP-600C 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 RP-600C 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.

RP-600C features a 1" titanium Tractrix horn dome Tweeter and 2 x 6.5" Cerametallic 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
RP-600C has a frequency range of 58-25k Hz 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 RP-600C's min frequency of 58Hz.
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
RP-600C and Ultra Center have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-600C sensitivity is rated at 97 dB and the Ultra Center's is at 87 dB. This 10 dB difference makes the Klipsch RP-600C a more sensitive speaker compared to SVS Ultra Center, 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.
RP-600C can handle a max power of 225 watts RMS from the amp the whereas RP-600C has a max power handling value of 125 watts RMS , 100 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. RP-600C has a Binding post which doesn't feature bi-amping/bi-wiring.

SVS Ultra Center's 5-Way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both RP-600C and Ultra Center 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 Klipsch RP-600C's and SVS Ultra Center's external dimensions. Klipsch RP-600C has external dimensions of 204.0 x 558.0 x 308.0mm ( 8 x 21-15/16 x 12-1/8inch) 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) .
Klipsch RP-600C is 3mm narrower and 3mm shorter than SVS Ultra Center but it is also 23mm deeper.
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 Klipsch RP-600C is approximately 1718.6cm2 / 266.4inch2 and base area of the SVS Ultra Center is approximately 1598.9cm2 / 247.8inch2. The RP-600C requires 7% more surface area than the Ultra Center 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 Klipsch RP-600C weighs 10.91kg / 24lbs and the SVS Ultra Center weighs 14.09kg / 31lbs. This makes the Ultra Center 29% heavier than the RP-600C.
Here is a comparison of how RP-600C and Ultra Center's weights compare with the average, max and min weights in Passive Center Channel class.
