Drivers

One of the fundamental differences between these two speakers is that RC-64 III 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.

Driver Klipsch RC-64 III SVS Ultra Center
Driver Setup 2-way 3-way
Tweeter 1-3/4-inch 1-inch
Midrange - 1 x 4-inch
Woofer 4 x 6.5-inch 2 x 6.5-inch

RC-64 III features a 1-3/4" titanium Tractrix horn Tweeter and 4 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

RC-64 III has a frequency range of 57-24k 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 RC-64 III's min frequency of 57Hz.

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.

RC-64 III can handle a max power of 225 watts RMS from the amp the whereas RC-64 III has a max power handling value of 200 watts RMS , 25 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 RC-64 III and Ultra Center features dual binding post speaker terminals for bi-amping or bi-wiring.

Klipsch RC-64 III has external dimensions of 204.0 x 909.0 x 388.0mm ( 8 x 35-3/4 x 15-1/4inch) 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 348mm narrower and 103mm less deeper than Klipsch RC-64 III but it is also 3mm taller.

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 RC-64 III is approximately 3526.9cm2 / 546.7inch2 and base area of the SVS Ultra Center is approximately 1598.9cm2 / 247.8inch2. The RC-64 III requires 121% 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 RC-64 III weighs 25.00kg / 55lbs and the SVS Ultra Center weighs 14.09kg / 31lbs. This makes the RC-64 III 77% heavier than the Ultra Center.
