Drivers
One of the fundamental differences between these two speakers is that SourcePoint 8 is a 2-way design whereas the SourcePoint 888 is a 3-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.

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 8 is a 8 ohms speaker compared to the SourcePoint 888 which has a nominal impedance of 6 ohms.
On the other hand, they have the same sensitivity of 87dBdB.

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 8 can handle a max power of 200 watts RMS from the amp the whereas SourcePoint 8 has a max power handling value of 150 watts RMS , 50 watts less than the SourcePoint 888.
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
SourcePoint 888 features 5-Way post posts which make bi-amping or bi-wiring possible. SourcePoint 8 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both SourcePoint 8 and SourcePoint 888 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 8's and MoFi SourcePoint 888's external dimensions. MoFi SourcePoint 8 has external dimensions of 456 x 290 x 320mm ( 18 x 11.4 x 12.6 inch) whereas MoFi SourcePoint 888 has external dimensions of 1070 x 320 x 410mm ( 42.1 x 12.6 x 16.1 inch) .
MoFi SourcePoint 888 is clearly the larger of the two speakers. Its body is 30mm wider, 614mm taller and 90mm deeper than MoFi SourcePoint 8.
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 8 is approximately 928.0cm2 / 143.8inch2 and base area of the MoFi SourcePoint 888 is approximately 1312.0cm2 / 203.4inch2. The SourcePoint 8 requires 29% less surface area than the SourcePoint 888 which gives it a small advantage on placement in tight spaces.
