History
What size room are the GoldenEar SuperCenter X and GoldenEar SC Ref 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:

Drivers
One of the fundamental differences between these two speakers is that SuperCenter X is a 2-way design whereas the SuperCenter Reference 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.

SuperCenter X features a " HVFR (High-Velocity Folded Ribbon) Tweeter and 2 x 5.25" Woofer. On the other hand, the SuperCenter Reference features a " Tweeter and 4 x 5.25" Woofer.
Frequency Response
SuperCenter X has a frequency range of 45-35k Hz whereas SuperCenter Reference has a frequency range of 33-35k Hz. With a minimum frequency of 33Hz, the SuperCenter Reference can go significantly deeper on the low side and provide stronger bass compared to the SuperCenter X's min frequency of 45Hz.
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
SuperCenter X and SuperCenter Reference have the same Impedance of 8 ohms but where they differ is the sensitivity levels. SuperCenter X sensitivity is rated at 90 dB and the SuperCenter Reference's is at 91 dB. This 1 dB difference makes the GoldenEar SC Ref a more sensitive speaker compared to GoldenEar SuperCenter X, 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.
SuperCenter Reference can handle a max power of 350 watts RMS, whereas SuperCenter X has a max power handling value of 200 watts RMS, 150 watts less than the SuperCenter Reference.
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.

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
SuperCenter X features 5-Way post type posts and SuperCenter Reference has a 5-Way post type posts. None of these speakers 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 GoldenEar SuperCenter X's and GoldenEar SC Ref's external dimensions. GoldenEar SuperCenter X has external dimensions of 150.0 x 510.0 x 283.0mm (5-7/8 x 20-1/16 x 11-1/8inch) whereas GoldenEar SC Ref has external dimensions of 150.0 x 889.0 x 281.0mm (5-7/8 x 35 x 11-1/16inch).
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 GoldenEar SuperCenter X is approximately 1443.3cm2 / 223.7inch2 and base area of the GoldenEar SC Ref is approximately 2498.1cm2 / 387.2inch2. The SuperCenter X requires 42% less surface area than the SuperCenter Reference 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 GoldenEar SuperCenter X weighs 6.82kg / 15lbs and the GoldenEar SC Ref weighs 14.09kg / 31lbs. This makes the SuperCenter Reference 107% heavier than the SuperCenter X.
Here is a comparison of how SuperCenter X and SuperCenter Reference's weights compare with the average, max and min weights in Passive Center Channel class.

Siblings in GoldenEar's SuperCenter series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass |
B |
GoldenEar SC Ref digs deeper - 33Hz against 45Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (90dB vs 91dB) - both want much the same power. |
| Headroom |
B |
GoldenEar SC Ref takes more power (350W vs 200W) - more in hand in a big room. |
| Size |
depends |
GoldenEar SuperCenter X is easier to place; GoldenEar SC Ref is bigger, which usually goes with fuller bass. Your room decides. |
| Price |
A |
GoldenEar SuperCenter X is cheaper - $749 against $1,899, about 61% less; arguably a different class. |
A GoldenEar SuperCenter X
B GoldenEar SC Ref
depends neither is better in the abstract - it turns on your room, placement 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?
The usual trade-off: GoldenEar SC Ref measures better, GoldenEar SuperCenter X costs about 61% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 45Hz anyway, which makes the cheaper GoldenEar SuperCenter X much easier to justify. Match it to your room: we rate GoldenEar SuperCenter X the better fit for a small room and a mid-size room, and GoldenEar SC Ref 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.
