What size room are the KEF Reference 1 Meta and MoFi SourcePoint 10 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:

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 MoFi SourcePoint 10 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Reference 1 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.

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 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
Reference 1 Meta has a frequency range of 45-35k Hz whereas SourcePoint 10 has a frequency range of 42-30k Hz. With a minimum frequency of 42Hz, the SourcePoint 10 can go slightly deeper then the Reference 1 Meta's min frequency of 45Hz.
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
Reference 1 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 Reference 1 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Reference 1 Meta sensitivity is rated at 85 dB and the SourcePoint 10's is rated at 91dB. This 6 dB difference makes the MoFi SourcePoint 10 a more sensitive speaker compared to KEF Reference 1 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.
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
Reference 1 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 Reference 1 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 Reference 1 Meta's and MoFi SourcePoint 10'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 MoFi SourcePoint 10 has external dimensions of 572 x 368 x 406mm ( 22.5 x 14.5 x 16 inch) .

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 MoFi SourcePoint 10 is approximately 1552.0cm2 / 240.6inch2. The Reference 1 Meta requires 44% less surface area than the SourcePoint 10 which gives it a small advantage on placement in tight spaces.
