What size room are the MoFi SourcePoint 888 and KEF R11 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

SourcePoint 888 features a 1.25" wide roll soft dome Tweeter, a 8" Midrange and 2 x 8" Paper-pulp Woofer with a Crossover frequency at 130Hz and 1.6kHz . On the other hand, the R11 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter, a 5" Midrange and 4 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 330Hz and 2500Hz.
Frequency Response
SourcePoint 888 has a frequency range of 32-30k Hz whereas R11 Meta has a frequency range of 46-28k Hz. With a minimum frequency of 32Hz, the SourcePoint 888 can go significantly deeper on the low side and provide stronger bass compared to the R11 Meta's min frequency of 46Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
SourcePoint 888 is a 6 ohms speaker compared to the R11 Meta which has a nominal impedance of 4 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 R11 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. SourcePoint 888 sensitivity is rated at 87dB and the R11 Meta's is rated at 90 dB. This 3 dB difference makes the KEF R11 Meta a more sensitive speaker compared to MoFi SourcePoint 888, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
R11 Meta can handle a max power of 300 watts RMS, whereas SourcePoint 888 has a max power handling value of 200 watts RMS, 100 watts less than the R11 Meta.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both SourcePoint 888 and R11 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R11 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both SourcePoint 888 and R11 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
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare MoFi SourcePoint 888's and KEF R11 Meta's external dimensions. MoFi SourcePoint 888 has external dimensions of 1070 x 320 x 410mm (42.1 x 12.6 x 16.1 inch) whereas KEF R11 Meta has external dimensions of 1296.0 x 312.0 x 385.0mm (51-inch x 12-1/4-inch x 15-1/8-inch).
KEF R11 Meta is 8mm narrower and 25mm less deeper than MoFi SourcePoint 888 but it is also 226mm taller.
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 MoFi SourcePoint 888 is approximately 1312.0cm2 / 203.4inch2 and base area of the KEF R11 Meta is approximately 1201.2cm2 / 186.2inch2. The SourcePoint 888 requires 9% more surface area than the R11 Meta which gives it a small disadvantage on placement in tight spaces.
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 MoFi SourcePoint 888 weighs 43.00kg / 94.6lbs and the KEF R11 Meta weighs 36.59kg / 80.5lbs. This makes the SourcePoint 888 18% heavier than the R11 Meta.
Here is a comparison of how SourcePoint 888 and R11 Meta's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | MoFi SourcePoint 888 digs deeper - 32Hz against 46Hz. |
| Amplifier needs | B | KEF R11 Meta is more sensitive (90dB vs 87dB), so it goes louder on the same amplifier. |
| Amplifier match | A | MoFi SourcePoint 888 is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | KEF R11 Meta takes more power (300W vs 200W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | MoFi SourcePoint 888: bi-amping; KEF R11 Meta: bi-amping. KEF R11 Meta sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | A | MoFi SourcePoint 888 is cheaper - $4,999 against $6,498, about 23% less. |
A MoFi SourcePoint 888 B KEF R11 Meta
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 46Hz anyway, so judge these on the other rows instead. Match it to your room: we rate MoFi SourcePoint 888 the better fit for a mid-size room, and KEF R11 Meta for a very large room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
