What size room are the MoFi SourcePoint 888 and DALI Opticon 6 II 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:

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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Both handle the same maximum of 200 watts RMS, though SourcePoint 888 is rated Up to 200 watts and Opticon 6 MK2 25-200 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
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
The size of a speaker can sometimes be 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.
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 MoFi SourcePoint 888 weighs 43.00kg / 94.6lbs and the DALI Opticon 6 II weighs 19.30kg / 42.5lbs. This makes the SourcePoint 888 123% heavier than the Opticon 6 MK2.
Here is a comparison of how SourcePoint 888 and Opticon 6 MK2's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - MoFi SourcePoint 888 costs roughly 2x what DALI Opticon 6 II does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | A | MoFi SourcePoint 888 digs deeper - 32Hz against 49Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 88dB) - both want much the same power. |
| Amplifier match | A | MoFi SourcePoint 888 is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (200W vs 200W). |
| Size | depends | DALI Opticon 6 II is easier to place; MoFi SourcePoint 888 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | MoFi SourcePoint 888: bi-amping; DALI Opticon 6 II: bi-amping. |
| Price | B | DALI Opticon 6 II is cheaper - $2,500 against $4,999, about 50% less; arguably a different class. |
A MoFi SourcePoint 888 B DALI Opticon 6 II
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: MoFi SourcePoint 888 measures better, DALI Opticon 6 II costs about about 100% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 49Hz anyway, which makes the cheaper DALI Opticon 6 II much easier to justify. Match it to your room: we rate MoFi SourcePoint 888 the better fit for a very large room; elsewhere the two are rated the same.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
