What size room are the GoldenEar SC Ref and JBL HDI-4500 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:

listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that SuperCenter Reference is a 3-way design whereas the HDI-4500 is a 2-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 Reference features a " Tweeter and 4 x 5.25" Woofer. On the other hand, the HDI-4500 features a 1" horn-loaded high-frequency compression Tweeter and 4 x 5.25" Advanced Aluminum Matrix cone Woofer.
Frequency Response
SuperCenter Reference has a frequency range of 33-35k Hz whereas HDI-4500 has a frequency range of 50-30k 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 HDI-4500's min frequency of 50Hz.
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 Reference is a 8 ohms speaker compared to the HDI-4500 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the HDI-4500 can provide this impedance level.
These two speakers also have different sensitivity levels. SuperCenter Reference sensitivity is rated at 91 dB and the HDI-4500's is rated at 90 dB. This 1 dB difference makes the GoldenEar SC Ref a more sensitive speaker compared to JBL HDI-4500, 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 HDI-4500 has a max power handling value of 250 watts RMS, 100 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.
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
SuperCenter Reference features 5-Way post type posts and HDI-4500 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 SC Ref's and JBL HDI-4500's external dimensions. GoldenEar SC Ref has external dimensions of 150.0 x 889.0 x 281.0mm (5-7/8 x 35 x 11-1/16inch) whereas JBL HDI-4500 has external dimensions of 197.0 x 842.0 x 310.0mm (7-3/4 x 33-1/8 x 12-3/16inch).
GoldenEar SC Ref is 47mm shorter and 29mm less deeper than JBL HDI-4500 but it is also 47mm wider.
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.
Near-identical footprints. JBL HDI-4500 is 29mm deeper, so it stands that much further out from the wall. JBL HDI-4500 is 47mm 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 GoldenEar SC Ref is approximately 2498.1cm2 / 387.2inch2 and base area of the JBL HDI-4500 is approximately 2610.2cm2 / 404.6inch2. The SuperCenter Reference requires 4% less surface area than the HDI-4500 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 SC Ref weighs 14.09kg / 31lbs and the JBL HDI-4500 weighs 20.15kg / 44.3lbs. This makes the HDI-4500 43% heavier than the SuperCenter Reference.

A generation apart: JBL HDI-4500 is the newer design, against a 2015 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | GoldenEar SC Ref digs deeper - 33Hz against 50Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (91dB vs 90dB) - both want much the same power. |
| Amplifier match | A | GoldenEar SC Ref is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | GoldenEar SC Ref takes more power (350W vs 250W) - more in hand in a big room. |
| Size | depends | GoldenEar SC Ref is easier to place; JBL HDI-4500 is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Passive Radiator vs Ported. |
| Price | evenly matched | Much the same money ($1,899 vs $1,925 a pair). |
A GoldenEar SC Ref B JBL HDI-4500
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?
GoldenEar SC Ref 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 50Hz anyway, so judge these on the other rows instead. Match it to your room: we rate GoldenEar SC Ref the better fit for a very large room, and JBL HDI-4500 for a mid-size 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.
