Debut 3.0 DC53 features a 1" Hard-Dome Tweeter and 2 x 5.25" Aramid fiber Woofer with a Crossover frequency at 1900Hz. On the other hand, the A135C features a 1" aluminum dome with HDI (High Definition Imaging) waveguide technology Tweeter and 6 x 3" polycellulose Woofer.
Frequency Response
Debut 3.0 DC53 has a frequency range of 57 to 38K Hz whereas A135C has a frequency range of 75-40k Hz. With a minimum frequency of 57Hz, the Debut 3.0 DC53 can go significantly deeper on the low side and provide stronger bass compared to the A135C's min frequency of 75Hz.
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
Debut 3.0 DC53 is a 4 ohms speaker compared to the A135C which has a nominal impedance of 6 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 Debut 3.0 DC53 can provide this impedance level.
These two speakers also have different sensitivity levels. Debut 3.0 DC53 sensitivity is rated at 87.5 dB and the A135C's is rated at 90 dB. This 2 dB difference makes the JBL Stage A135C a more sensitive speaker compared to ELAC Debut 3.0 DC53, 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.
A135C can handle a max power of 150 watts RMS, whereas Debut 3.0 DC53 has a max power handling value of 120 watts RMS, 30 watts less than the A135C.
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
Debut 3.0 DC53 features 5-way post type posts and A135C 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 ELAC Debut 3.0 DC53's and JBL Stage A135C's external dimensions. ELAC Debut 3.0 DC53 has external dimensions of 174.0 x 485.0 x 248.0mm (6-13/16-inch x 19-1/16-inch x 9-3/4-inch) whereas JBL Stage A135C has external dimensions of 105.0 x 747.0 x 186.0mm (4-1/8 x 29-3/8 x 7-5/16inch).
JBL Stage A135C is 69mm shorter and 62mm less deeper than ELAC Debut 3.0 DC53 but it is also 262mm wider.

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 ELAC Debut 3.0 DC53 is approximately 1202.8cm2 / 186.4inch2 and base area of the JBL Stage A135C is approximately 1389.4cm2 / 215.4inch2. The Debut 3.0 DC53 requires 13% less surface area than the A135C 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 ELAC Debut 3.0 DC53 weighs 8.73kg / 19.2lbs and the JBL Stage A135C weighs 7.46kg / 16.4lbs. This makes the Debut 3.0 DC53 17% heavier than the A135C.
Here is a comparison of how Debut 3.0 DC53 and A135C's weights compare with the average, max and min weights in Passive Center Channel class.

A generation apart: ELAC Debut 3.0 DC53 is the newer design, against a 2018 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 | ELAC Debut 3.0 DC53 digs deeper - 57Hz against 75Hz. |
| Amplifier needs | B | JBL Stage A135C is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| Amplifier match | B | JBL Stage A135C is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | JBL Stage A135C takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | JBL Stage A135C is easier to place; ELAC Debut 3.0 DC53 is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. JBL Stage A135C sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($299 vs $300 a pair). |
A ELAC Debut 3.0 DC53 B JBL Stage A135C
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?
JBL Stage A135C 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 75Hz anyway, so judge these on the other rows instead. In a large or open-plan room, ELAC Debut 3.0 DC53 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, JBL Stage A135C is the easier speaker to get right.
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.
