What size room are the KEF Reference 1 Meta and KEF R3 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 1 Meta KEF R3 Meta
Near-field Poor Poor
Small Room Poor Poor
Mid-size Room Good Good
Large Room Good Good
Very Large Room Average Average

(* 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 1 Meta and KEF R3 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 1 Meta and R3 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 1 x 6.5-inch 1 x 6.5-inch

Reference 1 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 1 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz. On the other hand, the R3 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 1 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 420Hz and 2300Hz.

Frequency Response

Reference 1 Meta has a frequency range of 45-35k Hz whereas R3 Meta has a frequency range of 58-28k Hz. With a minimum frequency of 45Hz, the Reference 1 Meta can go significantly deeper on the low side and provide stronger bass compared to the R3 Meta's min frequency of 58Hz.

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

Reference 1 Meta and R3 Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Reference 1 Meta sensitivity is rated at 85 dB and the R3 Meta's is at 87 dB. This 2 dB difference makes the KEF R3 Meta a more sensitive speaker compared to KEF Reference 1 Meta, hence will play louder with the same amount of watts.

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 1 Meta and the Reference 1 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 1 Meta can handle a max power of 200 watts RMS from the amp the whereas R3 Meta has a max power handling value of 180 watts RMS, 20 watts less than the Reference 1 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

Both Reference 1 Meta and R3 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.

KEF R3 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 1 Meta and R3 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 1 Meta's and KEF R3 Meta's external dimensions. KEF Reference 1 Meta has external dimensions of 440 x 205 x 422 mm ( 17.3 x 8.1 x 16.6 ) whereas KEF R3 Meta has external dimensions of 423.0 x 202.0 x 337.0mm ( 16-5/8-inch x 7-15/16-inch x 13-1/4-inch) .

KEF Reference 1 Meta is clearly the larger of the two speakers. Its body is 3mm wider, 17mm taller and 85mm deeper than KEF R3 Meta.

Below you can see the front view size comparison of KEF Reference 1 Meta and KEF R3 Meta 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 Reference 1 Meta is approximately 865.1cm2 / 134.1inch2 and base area of the KEF R3 Meta is approximately 680.7cm2 / 105.5inch2. The Reference 1 Meta requires 27% more surface area than the R3 Meta 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:

Weight Comparison

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 Reference 1 Meta weighs 18.20kg / 40lbs and the KEF R3 Meta weighs 12.41kg / 27.3lbs. This makes the Reference 1 Meta 47% heavier than the R3 Meta.

Here is a comparison of how Reference 1 Meta and R3 Meta's weights compare with the average, max and min weights in Passive Bookshelf class.
