In this review, we will be comparing R700 and Opticon 8 MK2, two Passive Floor-standing speakers from Polk Audio and DALI. Let's have a brief look at the main features
of Polk R700 and DALI Opticon 8 II first before getting into our more
detailed comparison.
What size room are the Polk R700 and DALI Opticon 8 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 Polk R700 and DALI Opticon 8 II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R700 features a 1" Pinnacle Ring Radiator Tweeter , a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz 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
R700 has a frequency range of 38-38k Hz whereas Opticon 8 MK2 has a frequency range of 38-30k Hz.
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
R700 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.
On the other hand, they have the same sensitivity of 88 dBdB.

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 R700 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
R700 has a bottom firing port whereas Opticon 8 MK2 has a rear firing ports. Polk R700'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.

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 Polk R700's and DALI Opticon 8 II's external dimensions. Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm ( 45 x 12.6 x 16.9inch) 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) .
Polk R700 is 6.2mm shorter and 30.7mm less deeper than DALI Opticon 8 II but it is also 75.7mm wider.
Below you can see the front view size comparison of Polk R700 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 Polk R700 is approximately 1373.6cm2 / 212.9inch2 and base area of the DALI Opticon 8 II is approximately 1124.6cm2 / 174.3inch2. The R700 requires 22% more surface area than the Opticon 8 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 Polk R700 weighs 35.90kg / 79lbs and the DALI Opticon 8 II weighs 37.10kg / 81.6lbs. This makes the Opticon 8 MK2 3% heavier than the R700.
