Chora 826 features a 1" TNF Al/Mg inverted dome Tweeter , a 6.5" Midrange and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 270Hz and 2700Hz. On the other hand, the 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.
Frequency Response
Chora 826 has a frequency range of 48-28k Hz whereas Opticon 8 MK2 has a frequency range of 38-30k 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 Chora 826's min frequency of 48Hz.
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
Floor-standing 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
Chora 826 is a 8 ohms speaker compared to the Opticon 8 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 8 MK2 can provide this impedance level.
These two speakers also have different sensitivity levels. Chora 826 sensitivity is rated at 91 dB and the Opticon 8 MK2's is rated at 88 dB. This 3 dB difference makes the Focal Chora 826 a more sensitive speaker compared to DALI Opticon 8 II, 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.
Chora 826 can handle a max power of 300 watts RMS from the amp the whereas Chora 826 has a max power handling value of 250 watts RMS , 50 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
Opticon 8 MK2 features Post posts which make bi-amping or bi-wiring possible. Chora 826 has a Binding post which doesn't feature bi-amping/bi-wiring.

DALI Opticon 8 II's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Chora 826 has a front firing port whereas Opticon 8 MK2 has a rear firing ports. Focal Chora 826's front-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Opticon 8 II with its rear-firing port.

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 Focal Chora 826's and DALI Opticon 8 II's external dimensions. Focal Chora 826 has external dimensions of 1053.0 x 305.0 x 404.0mm ( 41-1/2 x 12 x 15-7/8inch) whereas 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) .
Focal Chora 826 is 97mm shorter and 55mm less deeper than DALI Opticon 8 II but it is also 60mm wider.
Below you can see the front view size comparison of Focal Chora 826 and DALI Opticon 8 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 Focal Chora 826 is approximately 1232.2cm2 / 191.0inch2 and base area of the DALI Opticon 8 II is approximately 1124.6cm2 / 174.3inch2. The Chora 826 requires 10% more surface area than the Opticon 8 MK2 which gives it a small disadvantage on placement in tight spaces.
