In this review, we will be comparing two different type of speakers . KEF Q4 Meta is a Surround speaker whereas the 300 IW6 LCR is a In-wall speaker.
Let's have a brief look at the main features
of KEF Q4 Meta and Focal 300 IW6 LCR first before getting into our more
detailed comparison.
What size room are the KEF Q4 Meta and Focal 300 IW6 LCR 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 Q4 Meta and Focal 300 IW6 LCR compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Q4 Meta is a 2-way design whereas the 300 IW6 LCR is a 3-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.

Q4 Meta features a 1" vented aluminum dome with MAT absorber Hard-dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 1.8 kHz. On the other hand, the 300 IW6 LCR features a 1" Inverted Hard-Dome Tweeter and 2 x 6.5" Flax Woofer .
Frequency Response
Q4 Meta has a frequency range of 65-20k Hz whereas 300 IW6 LCR has a frequency range of 40-28kHz. With a minimum frequency of 40Hz, the 300 IW6 LCR can go significantly deeper on the low side and provide stronger bass compared to the Q4 Meta's min frequency of 65Hz.
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 Surround 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
Q4 Meta is a 4 ohms speaker compared to the 300 IW6 LCR which has a nominal impedance of 8 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 300 IW6 LCR's is rated at 92 dB. This 6 dB difference makes the Focal 300 IW6 LCR 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.
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 Spring post type posts and 300 IW6 LCR has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
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 Q4 Meta's and Focal 300 IW6 LCR's external dimensions. KEF Q4 Meta has external dimensions of 400 x 250 x 142 mm ( 15.7 x 9.8 x 5.6 in.) whereas Focal 300 IW6 LCR has external dimensions of 572.0 x 191.0 x 102.0mm ( 22.5000-inch x 7.5000-inch x 4.0000-inch) .
Focal 300 IW6 LCR is 59mm narrower and 40mm less deeper than KEF Q4 Meta but it is also 172mm taller.
