In this review, we will be comparing Opticon 8 MK2 and C 97 II, two Passive Floor-standing speakers from DALI and Jamo. Let's have a brief look at the main features
of DALI Opticon 8 II and Jamo C 97 II first before getting into our more
detailed comparison.
What size room are the DALI Opticon 8 II and Jamo C 97 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:
In the following sections, we will get into more detail in order to better understand how the DALI Opticon 8 II and Jamo C 97 II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer .
Frequency Response
Opticon 8 MK2 has a frequency range of 38-30k Hz whereas C 97 II has a frequency range of 32-24k Hz. With a minimum frequency of 32Hz, the C 97 II can go significantly deeper on the low side and provide stronger bass compared to the Opticon 8 MK2's min frequency of 38Hz.
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
Opticon 8 MK2 is a 4 ohms speaker compared to the C 97 II which has a nominal impedance of 6 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. Opticon 8 MK2 sensitivity is rated at 88 dB and the C 97 II's is rated at 89 dB. This 1 dB difference makes the Jamo C 97 II a more sensitive speaker compared to DALI Opticon 8 II, hence will play louder with the same amount of watts.
Sensitivity

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 C 97 II has a max power handling value of 180 watts RMS, 120 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 C 97 II features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Opticon 8 MK2 and C 97 II 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 Jamo C 97 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 Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm ( 42-1/8 x 9-3/4 x 15-13/16inch) .
Jamo C 97 II is 80mm shorter and 57mm less deeper than DALI Opticon 8 II but it is also 3mm wider.
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 Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The Opticon 8 MK2 requires 13% more surface area than the C 97 II 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 Jamo C 97 II weighs 24.55kg / 54lbs. This makes the Opticon 8 MK2 51% heavier than the C 97 II.
Here is a comparison of how Opticon 8 MK2 and C 97 II's weights compare with the average, max and min weights in Passive Floor-standing class.
