What size room are the MoFi SourcePoint 888 and KEF R7 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:

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 R7 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter, a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2400Hz.
Frequency Response
SourcePoint 888 has a frequency range of 32-30k Hz whereas R7 Meta has a frequency range of 48-28k 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 R7 Meta's min frequency of 48Hz.
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 R7 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 R7 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. SourcePoint 888 sensitivity is rated at 87dB and the R7 Meta's is rated at 88 dB. This 1 dB difference makes the KEF R7 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.
R7 Meta can handle a max power of 250 watts RMS, whereas SourcePoint 888 has a max power handling value of 200 watts RMS, 50 watts less than the R7 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 R7 Meta features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R7 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 R7 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 R7 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 R7 Meta has external dimensions of 1112.0 x 312.0 x 385.0mm (43-3/4-inch x 12-1/4-inch x 15-1/8-inch).
KEF R7 Meta is 8mm narrower and 25mm less deeper than MoFi SourcePoint 888 but it is also 42mm 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 R7 Meta is approximately 1201.2cm2 / 186.2inch2. The SourcePoint 888 requires 9% more surface area than the R7 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 R7 Meta weighs 29.36kg / 64.6lbs. This makes the SourcePoint 888 46% heavier than the R7 Meta.
Here is a comparison of how SourcePoint 888 and R7 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 48Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| 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 R7 Meta takes more power (250W 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 R7 Meta: bi-amping. KEF R7 Meta sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($4,999 vs $4,998 a pair). |
A MoFi SourcePoint 888 B KEF R7 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?
MoFi SourcePoint 888 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 48Hz 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; elsewhere the two are rated the same.
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.
