What size room are the KEF Q1 Meta and DALI Opticon 1 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:

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 KEF Q1 Meta and DALI Opticon 1 II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Q1 Meta features a 1" vented aluminum dome with MAT absorber Hard dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2.1 kHz. On the other hand, the Opticon 1 MK2 features a 1.125" Soft-Dome Tweeter and 1 x 4.75" Wood Fiber Woofer with a Crossover frequency at 3000Hz.
Frequency Response
Q1 Meta has a frequency range of 51-20k Hz whereas Opticon 1 MK2 has a frequency range of 62-26k Hz. With a minimum frequency of 51Hz, the Q1 Meta can go significantly deeper on the low side and provide stronger bass compared to the Opticon 1 MK2's min frequency of 62Hz.
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
Bookshelf Speakers
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
Q1 Meta and Opticon 1 MK2 have the same Impedance of 4 ohms and their sensitivity is also same at 86 dB.
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 Q1 Meta and the Q1 Meta 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.
Q1 Meta can handle a max power of 150 watts RMS from the amp the whereas Opticon 1 MK2 has a max power handling value of 100 watts RMS, 50 watts less than the Q1 Meta.
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
Q1 Meta features Post type posts and Opticon 1 MK2 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
KEF Q1 Meta's Binding Post terminals
DALI Opticon 1 II's Post terminals
Cabinet Type and Port Position
Both Q1 Meta and Opticon 1 MK2 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 KEF Q1 Meta's and DALI Opticon 1 II's external dimensions. KEF Q1 Meta has external dimensions of 302 x 180 x 277 mm ( 11.9 x 7.1 x 10.9 in.) whereas DALI Opticon 1 II has external dimensions of 254.0 x 153.0 x 235.0mm ( 10 x 6 x 9-1/4inch) .
KEF Q1 Meta is clearly the larger of the two speakers. Its body is 27mm wider, 48mm taller and 42mm deeper than DALI Opticon 1 II.
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 KEF Q1 Meta is approximately 498.6cm2 / 77.3inch2 and base area of the DALI Opticon 1 II is approximately 359.6cm2 / 55.7inch2. The Q1 Meta requires 39% more surface area than the Opticon 1 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 KEF Q1 Meta weighs 6.09kg / 13.4lbs and the DALI Opticon 1 II weighs 4.50kg / 9.9lbs. This makes the Q1 Meta 35% heavier than the Opticon 1 MK2.
Here is a comparison of how Q1 Meta and Opticon 1 MK2's weights compare with the average, max and min weights in Passive Bookshelf class.
