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 Opticon 6 MK2 features a 17 x 45 mm ribbon + 1.125" Soft-dome + ribbon Hybrid Tweeter and 2 x 6.5" Wood Fiber Woofer with a Crossover frequency at 800Hz, 2200Hz and 14,000Hz.
Frequency Response
SourcePoint 888 has a frequency range of 32-30k Hz whereas Opticon 6 MK2 has a frequency range of 49-30k 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 Opticon 6 MK2's min frequency of 49Hz.
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.

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 Opticon 6 MK2 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 Opticon 6 MK2 can provide this impedance level.
These two speakers also have different sensitivity levels. SourcePoint 888 sensitivity is rated at 87dB and the Opticon 6 MK2's is rated at 88 dB. This 1 dB difference makes the DALI Opticon 6 II 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.
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 Opticon 6 MK2 features dual binding post speaker terminals for bi-amping or bi-wiring.
DALI Opticon 6 II's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both SourcePoint 888 and Opticon 6 MK2 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 DALI Opticon 6 II'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 DALI Opticon 6 II has external dimensions of 1010.0 x 195.0 x 340.0mm ( 39-3/4 x 7-5/8 x 13-3/8inch) .
MoFi SourcePoint 888 is clearly the larger of the two speakers. Its body is 125mm wider, 60mm taller and 70mm deeper than DALI Opticon 6 II.
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 DALI Opticon 6 II is approximately 663.0cm2 / 102.8inch2. The SourcePoint 888 requires 98% more surface area than the Opticon 6 MK2 which gives it a small disadvantage on placement in tight spaces.
