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
Q4 Meta is a 4 ohms speaker compared to the Debut 2.0 B6.2 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 Q4 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Q4 Meta sensitivity is rated at 86 dB and the Debut 2.0 B6.2's is rated at 87 dB. This 1 dB difference makes the ELAC Debut 2.0 B6.2 a more sensitive speaker compared to KEF Q4 Meta, hence will play louder with the same amount of watts.

Power Range
Power
range 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.
Q4 Meta can handle a max power of 150 watts RMS from the amp the whereas Debut 2.0 B6.2 has a max power handling value of 120 watts RMS, 30 watts less than the Q4 Meta.
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
Q4 Meta 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.
