Opticon 8 MK2 features a 17 x 45 mm ribbon + 1.125" Soft-dome + ribbon Hybrid Tweeter , a 6.5" Midrange and 2 x 8" Wood Fiber Woofer with a Crossover frequency at 380Hz, 2200Hz and 14,000Hz. 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
Opticon 8 MK2 has a frequency range of 38-30k Hz whereas Opticon 6 MK2 has a frequency range of 49-30k Hz. With a minimum frequency of 38Hz, the Opticon 8 MK2 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 Floor-standing class in our database.

High Frequency

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
Opticon 8 MK2 and Opticon 6 MK2 have the same Impedance of 4 ohms and their sensitivity is also same at 88 dB.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Opticon 8 MK2 and the Opticon 8 MK2 can provide this impedance level.

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.
Opticon 8 MK2 can handle a max power of 300 watts RMS from the amp the whereas Opticon 6 MK2 has a max power handling value of 200 watts RMS, 100 watts less than the Opticon 8 MK2.
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 Opticon 8 MK2 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 Opticon 8 MK2 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 DALI Opticon 8 II's and DALI Opticon 6 II's external dimensions. DALI Opticon 8 II has external dimensions of 1150.0 x 245.0 x 459.0mm ( 45-1/4 x 9-1/2 x 18-1/16inch) 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) .
DALI Opticon 8 II is clearly the larger of the two speakers. Its body is 50mm wider, 140mm taller and 119mm deeper than DALI Opticon 6 II.
Below you can see the front view size comparison of DALI Opticon 8 II and DALI Opticon 6 II in scale.

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 DALI Opticon 8 II is approximately 1124.6cm2 / 174.3inch2 and base area of the DALI Opticon 6 II is approximately 663.0cm2 / 102.8inch2. The Opticon 8 MK2 requires 70% 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 DALI Opticon 8 II weighs 37.10kg / 81.6lbs and the DALI Opticon 6 II weighs 19.30kg / 42.5lbs. This makes the Opticon 8 MK2 92% heavier than the Opticon 6 MK2.
Here is a comparison of how Opticon 8 MK2 and Opticon 6 MK2's weights compare with the average, max and min weights in Passive Floor-standing class.
