What size room are the DALI Oberon 1 and KEF Q350 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 Oberon 1 and KEF Q350 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Oberon 1 features a 1.125" Soft-Dome Tweeter and 1 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2800Hz. On the other hand, the Q350 features a 1" vented aluminum Dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Oberon 1 has a frequency range of 51-26k Hz whereas Q350 has a frequency range of 63-28k Hz. With a minimum frequency of 51Hz, the Oberon 1 can go significantly deeper on the low side and provide stronger bass compared to the Q350's min frequency of 63Hz.
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.

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
Oberon 1 is a 6 ohms speaker compared to the Q350 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Oberon 1 sensitivity is rated at 86 dB and the Q350's is rated at 87 dB. This 1 dB difference makes the KEF Q350 a more sensitive speaker compared to DALI Oberon 1, hence will play louder with the same amount of watts.

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.
Oberon 1 can handle a max power of 120 watts RMS from the amp the whereas Oberon 1 has a max power handling value of 100 watts RMS , 20 watts less than the Q350.
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
Oberon 1 features Post type posts and Q350 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Oberon 1 and Q350 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 Oberon 1's and KEF Q350's external dimensions. DALI Oberon 1 has external dimensions of 275.0 x 164.0 x 228.0mm ( 10-13/16 x 6-7/16 x 8-15/16inch) whereas KEF Q350 has external dimensions of 358.0 x 210.0 x 306.0mm ( 14.0 x 8.2 x 12.0inch) .
KEF Q350 is clearly the larger of the two speakers. Its body is 46mm wider, 83mm taller and 78mm deeper than DALI Oberon 1.
Below you can see the front view size comparison of DALI Oberon 1 and KEF Q350 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 Oberon 1 is approximately 373.9cm2 / 58.0inch2 and base area of the KEF Q350 is approximately 642.6cm2 / 99.6inch2. The Oberon 1 requires 42% less surface area than the Q350 which gives it a small advantage on placement in tight spaces.
