Elac Debut 2.0 B6.2 vs. KEF Q150 – Detailed Comparison
We have compared every factor in detail, whether built-in quality, frequency response, or power range.
Design & Build Quality
The Elac Debut 2.0 B6.2 and the KEF Q150 feature a sleek and modern design that complements any home audio setup.
The Elac Debut 2.0 B6.2 sports a simple yet elegant look with a black ash vinyl finish, while the KEF Q150 comes in three finishes: black, white, or walnut.
Both speakers are made from high-quality materials and feel well-built, ensuring durability and longevity.
The Elac Debut 2.0 B6.2 weighs 16.31 pounds, while the KEF Q150 weighs 25 pounds. The Elac Debut 2.0 B6.2 is 34.8% lighter than the KEF Q150.
Regarding dimensions, the Elac Debut 2.0 B6.2 measures 10.6 x 7.7 x 14.8 inches, and KEF Q150, on the other hand, has 21 x 16 x 17 inches (533.4 x 406.4 x 431.8 mm) dimension.
Speaking of the Elac Debut 2.0 B6.2, it features a tweeter and woofer on the front side. The front baffle is covered with a removable black cloth grille that protects the drivers while maintaining a clean appearance. The Elac B6.2 also has a port on the front that gives more flexibility in speaker placement regarding closeness with walls.
The Kef Q150 is a more elegant speaker with a new cabinet and sleek new finishes and features an improved 5.25″ Uni-Q driver Array. The port is also available on the rear side of the speaker.
Regarding design, Elac speakers have a traditional look with a front tweeter, woofer, and port. The Kef Q150 has a more modern, eye-catching design with a curved front baffle. It is your personal preference what you like, but we love the design of the Kef Q150. Moving to the build quality of both speakers, both speakers are very well built with MDF wood cabinets. Elac Debut 2.0 B6.2 is slightly larger and heavier than KEF Q150.
In design and build quality, we will go with Kef Q150.
Woofer & Tweeter Type:
The Elac Debut 2.0 B6.2 and the KEF Q150 speakers utilize different tweeter and woofer technologies, contributing to their distinctive sound signatures.
The Elac Debut 2.0 B6.2 features a 1-inch newly developed soft dome tweeter with a wide roll surround, which allows for improved high-frequency dispersion and reduced distortion.
The aramid fiber newly developed woofer features a new tighter weave pattern for a smooth frequency response and a deep bass output. The woofer size measures 6 ½ inches. The addition of the bass port further improves the bass response. And this combination allows for a tight and controlled bass response with excellent midrange clarity.
On the other hand, we have Kef Q150, which features very distinctive technology. 1-inch vented aluminum dome tweeter with KEF’s patented “tangerine” waveguide technology. This waveguide helps to disperse high frequencies more evenly and widens the sweet spot for a more immersive listening experience.
The woofer in the Q150 is a 5.25-inch Uni-Q driver, which combines a midrange cone and a tweeter at the center for coherent and accurate sound reproduction. The Uni-Q driver design also helps to create a precise soundstage with excellent imaging and detail retrieval.
In conclusion, both speakers feature high-quality material for their tweeter and woofers to deliver top-notch sound quality. But the addition of the Uni Q array makes a huge difference. That delivers perfect time frequencies and three-dimensional soundstages. In two way design, the Kef Q150 delivers a three-way speaker experience.
Audio Performance
When it comes to audio performance, the Elac Debut 2.0 B6.2 and the KEF Q150 each have their unique strengths.
One that we cannot deny is that both sound amazing, which is one reason they are best-selling speakers.
As we already talk about their tweeter and woofer types, how each works, and their strengths, we are not going into that detail further.
The Elac Debut 2.0 B6.2 with a 1-inch tweeter and 6.5-inch delivers a warm and detailed sound signature with a frequency response of 44Hz to 35kHz.
The KEF Q150, on the other hand, boasts a 1-inch aluminum dome tweeter and a 5.25-inch Uni-Q driver array, which places the tweeter in the center of the woofer for improved sound dispersion and imaging. The KEF Q150 offers a more neutral and balanced sound with a frequency response of 51Hz to 28kHz.
Both speakers provide clear and accurate audio performance, but the KEF Q150 may have a slight advantage in terms of imaging and soundstage due to its Uni-Q driver design.
I tried to find some sources that help you to hear how both speakers sound, and luckily, I found few. But you need to be aware while making any judgment that the room environment, overall setup, the type of connection, and what you’re listening to all make differences.

Power Range
If you are unsure about this factor, here is the brief. We inspect power range in two forms; peak and RMS. Peak power range indicates the maximum power a speaker can handle and how loud it can be at the range. RMS (Root Mean Square), on the other hand, represents the continuous power handling of a speaker.
Power range is crucial since it tells what amplifier range you can connect with the speaker—setting up an amp having a higher power range than the speaker can damage the internal components.
The Elac Debut 2.0 B6.2’s max power from an amplifier is 120 watts RMS, whereas the KEF Q150 can handle a max capacity of 100 watts RMS.
While you might consider the higher the power range, the louder the speaker, this is not always true. System efficiencies, impedance, and sensitivity decide the loudness of the sound.
Impedance and Sensitivity
As you know, impedance is the resistance to the current flow, while sensitivity refers to the speaker’s efficiency in converting electrical signals into acoustic ones. Impedance plays a crucial role in regulating the quality and power of the speaker.
The higher the impedance, the reduced the power output will be, resulting in muffling and low sound output. The low impedance, on the other hand, will result in overheating or impairing the system.
The KEF Q150 supports an impedance of 8 ohms, while the Elac Debut 2.0 B6.2 supports a nominal impedance of 6 ohms. The sensitivity of these speakers is 86 and 87 dB, respectively.
The higher sensitivity means the speaker can produce more sound with less power input than a low-sensitivity speaker. Although speakers have a 1 dB difference, this still makes the Elac Debut 2.0 B6.2 louder than the KEF Q150. While connecting an amplifier with speakers, ensure to match the impedance rating.
Connectivity Technology & Mounting Type:
How versatile the 2-way bookshelf speaker is in connecting devices should also be your concern. The standard connectivity mode both speakers share is wired.
Elac Debut 2.0 B6.2 vs. KEF Q150, let’s first talk about the KEF Q150. The KEF Q150 bookshelf is compatible with smartphones, laptops, tablets, and PCs. The Elac Debut 2.0 B6.2, on the other hand, is also compatible with devices, including laptops, PCs, smartphones, and laptops.
Both speakers support an AUX 3.5mm port, letting you link source streaming devices of your choice. Since both speakers are bookshelf, the standard mounting type they support is shelf mount. However, the Elac Debut 2.0 B6.2 has more to offer.
Besides shelf mounting, you can adjust the Elac Debut 2.0 B6.2 on the floor or tabletop. Despite the placement, the speaker uses its wide-dispersion waveguide technology to surround the sound in the room efficiently. Another plus point about the floor mounting is the less vibration than other speakers shaking the room.
Our Favorite
While the Elac Debut 2.0 B6.2 is a decent option with a more affordable price tag, we found KEF Q150 the best choice.
The KEF Q150 boasts impressive audio performance and build quality, making it a top contender in the bookshelf speaker market. Its Uni-Q driver, which features a concentric tweeter and midrange driver, delivers exceptionally detailed and accurate sound reproduction with a wide soundstage. The Q150’s frequency response is well-balanced, providing a natural and immersive listening experience across various music genres and multimedia content. The KEF Q150 features a solid build with high-quality materials, ensuring durability and longevity.
That does not mean Elac Debut 2.0 B6.2 is a bad choice. Not Elac is one of the top contenders for best bookshelf speakers, and the proof is their positive user feedback. But we believe Kef Q150 is a better option and worth investing a few extra dollars between the two.
