In this review, we will be comparing Q350 and Debut 2.0 B6.2, two Passive Bookshelf speakers from KEF and ELAC. Let's have a brief look at the main features
of KEF Q350 and ELAC Debut 2.0 B6.2 first before getting into our more
What size room are the KEF Q350 and ELAC Debut 2.0 B6.2 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:
In the following sections, we will get into more detail in order to better understand how the KEF Q350 and ELAC Debut 2.0 B6.2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

1 x 6.5-inch
1 x 6.5-inch
Q350 features a 1" vented aluminum Dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz. On the other hand, the Debut 2.0 B6.2 features a 1" Cloth Soft-Dome Tweeter and 1 x 6.5" Woven Aramid-Fiber Woofer with a Crossover frequency at 2200Hz.
Q350 has a frequency range of 63-28k Hz whereas Debut 2.0 B6.2 has a frequency range of 44-35k Hz. With a minimum frequency of 44Hz, the Debut 2.0 B6.2 can go significantly deeper on the low side and provide stronger bass compared to the Q350's min frequency of 63Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Q350 is a 8 ohms speaker compared to the Debut 2.0 B6.2 which has a nominal impedance of 6 ohms.
On the other hand, they have the same sensitivity of 87 dBdB.
is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Q350 features 5-Way post type posts and Debut 2.0 B6.2 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Q350 has a rear firing port whereas Debut 2.0 B6.2 has a front firing ports. ELAC Debut 2.0 B6.2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF Q350 with its rear-firing port.
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare KEF Q350's and ELAC Debut 2.0 B6.2's external dimensions. KEF Q350 has external dimensions of 358.0 x 210.0 x 306.0mm ( 14.0 x 8.2 x 12.0inch) whereas ELAC Debut 2.0 B6.2 has external dimensions of 375.0 x 195.0 x 268.0mm ( 14.7 x 7.6 x 10.5inch) .
ELAC Debut 2.0 B6.2 is 15mm narrower and 38mm less deeper than KEF Q350 but it is also 17mm taller.
Below you can see the front view size comparison of KEF Q350 and ELAC Debut 2.0 B6.2 in scale.
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 KEF Q350 is approximately 642.6cm2 / 99.6inch2 and base area of the ELAC Debut 2.0 B6.2 is approximately 522.6cm2 / 81.0inch2. The Q350 requires 23% more surface area than the Debut 2.0 B6.2 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 KEF Q350 weighs 7.60kg / 16.7lbs and the ELAC Debut 2.0 B6.2 weighs 7.40kg / 16.3lbs. This makes the Q350 3% heavier than the Debut 2.0 B6.2.
Here is a comparison of how Q350 and Debut 2.0 B6.2's weights compare with the average, max and min weights in Passive Bookshelf class.
