What size room are the DALI Opticon 2 II and Polk L200 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the DALI Opticon 2 II and Polk L200 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Opticon 2 MK2 features a 1.125" Soft-Dome Tweeter and 1 x 6.5" Wood Fiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the L200 features a 1" Ring Radiator Tweeter and 1 x 6.5" Polypropylene Woofer with a Crossover frequency at 2600Hz.
Frequency Response
Opticon 2 MK2 has a frequency range of 59-25k Hz whereas L200 has a frequency range of 46-38k Hz. With a minimum frequency of 46Hz, the L200 can go significantly deeper on the low side and provide stronger bass compared to the Opticon 2 MK2's min frequency of 59Hz.
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 Bookshelf class in our database.
Low Frequency

High Frequency
Bookshelf 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 2 MK2 and L200 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Opticon 2 MK2 sensitivity is rated at 86.5 dB and the L200's is at 85.5 dB. This 1 dB difference makes the DALI Opticon 2 II a more sensitive speaker compared to Polk L200, 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 Opticon 2 MK2 and the Opticon 2 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 2 MK2 can handle a max power of 200 watts RMS from the amp the whereas Opticon 2 MK2 has a max power handling value of 150 watts RMS , 50 watts less than the L200.
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
L200 features Post posts which make bi-amping or bi-wiring possible. Opticon 2 MK2 has a Post which doesn't feature bi-amping/bi-wiring.

Polk L200's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Opticon 2 MK2 and L200 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 2 II's and Polk L200's external dimensions. DALI Opticon 2 II has external dimensions of 351.0 x 196.0 x 297.0mm ( 13-13/16 x 7-11/16 x 11-11/16inch) whereas Polk L200 has external dimensions of 399.0 x 213.0 x 339.0mm ( 15-11/16 x 8-3/8 x 13-5/16inch) .
Polk L200 is clearly the larger of the two speakers. Its body is 17mm wider, 48mm taller and 42mm deeper than DALI Opticon 2 II.
Below you can see the front view size comparison of DALI Opticon 2 II and Polk L200 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 2 II is approximately 582.1cm2 / 90.2inch2 and base area of the Polk L200 is approximately 722.1cm2 / 111.9inch2. The Opticon 2 MK2 requires 19% less surface area than the L200 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 2 II weighs 7.73kg / 17lbs and the Polk L200 weighs 10.00kg / 22lbs. This makes the L200 29% heavier than the Opticon 2 MK2.
Here is a comparison of how Opticon 2 MK2 and L200's weights compare with the average, max and min weights in Passive Bookshelf class.
