What size room are the Paradigm 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:

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Premier 600C and Ultra Center are 3-way speakers.

Premier 600C features a 1" aluminum X-PAL dome with PPA (Perforated Phase-Aligning) lens Tweeter, a 4" Midrange and 4 x 6.5" carbon-infused polypropylene 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
Premier 600C has a frequency range of 60-25k 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 Premier 600C's min frequency of 60Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Premier 600C and Ultra Center have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Premier 600C sensitivity is rated at 94 dB and the Ultra Center's is at 87 dB. This 7 dB difference makes the Paradigm 600C a more sensitive speaker compared to SVS Ultra Center, hence will play louder with the same amount of watts.
Sensitivity
Center Channel Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Ultra Center can handle a max power of 225 watts RMS, whereas Premier 600C has a max power handling value of 180 watts RMS, 45 watts less than the Ultra Center.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Ultra Center features 5-Way post posts which make bi-amping or bi-wiring possible. Premier 600C has a Binding post which doesn't feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Paradigm 600C's and SVS Ultra Center's external dimensions. Paradigm 600C has external dimensions of 208.0 x 907.0 x 348.0mm (8-3/16 x 35-11/16 x 13-11/16inch) 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).
Paradigm 600C is clearly the larger of the two speakers. Its body is 346mm wider, 1mm taller and 63mm deeper than SVS Ultra Center.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Paradigm 600C needs about 97% more floor or shelf area. Paradigm 600C is 63mm deeper, so it stands that much further out from the wall.
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 Paradigm 600C is approximately 3156.4cm2 / 489.2inch2 and base area of the SVS Ultra Center is approximately 1598.9cm2 / 247.8inch2. The Premier 600C requires 97% 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 Paradigm 600C weighs 19.55kg / 43lbs and the SVS Ultra Center weighs 14.09kg / 31lbs. This makes the Premier 600C 39% heavier than the Ultra Center.
Here is a comparison of how Premier 600C and Ultra Center's weights compare with the average, max and min weights in Passive Center Channel class.

A generation apart: Paradigm 600C is the newer design, against a 2013 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | SVS Ultra Center digs deeper - 45Hz against 60Hz. |
| Amplifier needs | A | Paradigm 600C is more sensitive (94dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | B | SVS Ultra Center takes more power (225W vs 180W) - more in hand in a big room. |
| Size | depends | SVS Ultra Center is easier to place; Paradigm 600C is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Passive Radiator vs Ported. |
| Expandability | depends | SVS Ultra Center: bi-amping. Paradigm 600C sits in a wider range (12 models), so a matched surround system is easier later. |
| Price | B | SVS Ultra Center is cheaper - $799 against $1,099, about 27% less. |
A Paradigm 600C B SVS Ultra Center
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS Ultra Center has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Paradigm 600C the better fit for a small room, and SVS Ultra Center for a large room and a very large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
