Drivers
One of the fundamental differences between these two speakers is that R3 Meta is a 3-way design whereas the SourcePoint 10 is a 2-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.

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. On the other hand, the SourcePoint 10 features a 1.25" wide roll soft dome Tweeter and 1 x 10" Paper-pulp Woofer with a Crossover frequency at 1600 Hz.
Frequency Response
R3 Meta has a frequency range of 58-28k Hz whereas SourcePoint 10 has a frequency range of 42-30k Hz. With a minimum frequency of 42Hz, the SourcePoint 10 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.

High Frequency
Bookshelf Speakers
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
R3 Meta is a 4 ohms speaker compared to the SourcePoint 10 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 R3 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R3 Meta sensitivity is rated at 87 dB and the SourcePoint 10's is rated at 91dB. This 4 dB difference makes the MoFi SourcePoint 10 a more sensitive speaker compared to KEF R3 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.
R3 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 SourcePoint 10.
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
R3 Meta features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. SourcePoint 10 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both R3 Meta and SourcePoint 10 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 R3 Meta's and MoFi SourcePoint 10's external dimensions. 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) whereas MoFi SourcePoint 10 has external dimensions of 572 x 368 x 406mm ( 22.5 x 14.5 x 16 inch) .
MoFi SourcePoint 10 is clearly the larger of the two speakers. Its body is 166mm wider, 149mm taller and 85mm deeper than KEF R3 Meta.
Below you can see the front view size comparison of KEF R3 Meta and MoFi SourcePoint 10 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 R3 Meta is approximately 680.7cm2 / 105.5inch2 and base area of the MoFi SourcePoint 10 is approximately 1552.0cm2 / 240.6inch2. The R3 Meta requires 56% less surface area than the SourcePoint 10 which gives it a small advantage 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 KEF R3 Meta weighs 12.41kg / 27.3lbs and the MoFi SourcePoint 10 weighs 21.00kg / 46.2lbs. This makes the SourcePoint 10 69% heavier than the R3 Meta.
Here is a comparison of how R3 Meta and SourcePoint 10's weights compare with the average, max and min weights in Passive Bookshelf class.
