What size room are the KEF Reference 4 Meta and KEF Reference 5 Meta 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:

Listening Environment* KEF Reference 4 Meta KEF Reference 5 Meta
Near-field Are you nuts? Are you nuts?
Small Room Bad Poor
Mid-size Room Poor Average
Large Room Good Good
Very Large Room Good Good

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the KEF Reference 4 Meta and KEF Reference 5 Meta compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers

Both Reference 4 Meta and Reference 5 Meta are 3-way speakers.

Driver Setup 3-way 3-way
Tweeter 1-inch 1-inch
Midrange 1 x 5-inch 1 x 5-inch
Woofer 4 x 6.5-inch 4 x 6.5-inch

Reference 4 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 4 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz. On the other hand, the Reference 5 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 4 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz.

Frequency Response

Reference 4 Meta has a frequency range of 48-35k Hz whereas Reference 5 Meta has a frequency range of 40-35k Hz. With a minimum frequency of 40Hz, the Reference 5 Meta can go significantly deeper on the low side and provide stronger bass compared to the Reference 4 Meta's min frequency of 48Hz.

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 Center Channel 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

Reference 4 Meta and Reference 5 Meta have the same Impedance of 4 ohms and their sensitivity is also same at 88 dB.

One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Reference 4 Meta and the Reference 4 Meta can provide this impedance level.

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.

Reference 4 Meta and Reference 5 Meta has the same power range of 50-400 watts.

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

Both Reference 4 Meta and Reference 5 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.

KEF Reference 4 Meta Terminals
KEF Reference 4 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring

KEF Reference 5 Meta Terminals
KEF Reference 5 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Both Reference 4 Meta and Reference 5 Meta have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 Reference 4 Meta's and KEF Reference 5 Meta's external dimensions. KEF Reference 4 Meta has external dimensions of 205 x 1090 x 463 mm ( 8.1 x 42.9 x 18.2 in.) whereas KEF Reference 5 Meta has external dimensions of 1402 x 323 x 467 mm ( 55.2 x 12.7 x 18.4 in.) .

KEF Reference 4 Meta is 1197mm shorter and 4mm less deeper than KEF Reference 5 Meta but it is also 767mm wider.

Below you can see the front view size comparison of KEF Reference 4 Meta and KEF Reference 5 Meta in scale.
