Tweeter	1.15-inch	17 x 45 mm ribbon + 1.125-inch
Midrange	1 x 6-inch	1 x 6.5-inch
Woofer	2 x 6.5-inch	2 x 8-inch

Lumina V features a 1.15" high definition DAD Tweeter , a 6" Midrange and 2 x 6.5" paper cone Woofer with a Crossover frequency at 260 and 2600 Hz. 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

Lumina V has a frequency range of 38-24k Hz whereas Opticon 8 MK2 has a frequency range of 38-30k Hz.

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

Lumina V and Opticon 8 MK2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Lumina V sensitivity is rated at 90 dB and the Opticon 8 MK2's is at 88 dB. This 2 dB difference makes the Sonus Lumina V a more sensitive speaker compared to DALI Opticon 8 II, hence will play louder with the same amount of watts.

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 Lumina V and the Lumina V 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.

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 Lumina V and Opticon 8 MK2 features dual binding post speaker terminals for bi-amping or bi-wiring.

DALI Opticon 8 II's Post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Lumina V has a bottom firing port whereas Opticon 8 MK2 has a rear firing ports. Sonus Lumina V's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Opticon 8 II with its rear-firing port.

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 Sonus Lumina V is approximately 1044.4cm² / 161.9inch² and base area of the DALI Opticon 8 II is approximately 1124.6cm² / 174.3inch². The Lumina V requires 7% less surface area than the Opticon 8 MK2 which gives it a small advantage 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 Sonus Lumina V weighs 22.50kg / 49.5lbs and the DALI Opticon 8 II weighs 37.10kg / 81.6lbs. This makes the Opticon 8 MK2 65% heavier than the Lumina V.
