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.
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.
Low Frequency
Bookshelf Speakers
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
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.

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.
SourcePoint 888 can handle a max power of 250 watts RMS from the amp the whereas SourcePoint 888 has a max power handling value of 200 watts RMS , 50 watts less than the R7 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 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
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 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.
