In this review, we will be comparing Diamond 12.4 and Oberon 7, two Passive Floor-standing speakers from Wharfedale and DALI. Let's have a brief look at the main features
of Wharfedale Diamond 12.4 and DALI Oberon 7 first before getting into our more
detailed comparison.
What size room are the Wharfedale Diamond 12.4 and DALI Oberon 7 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 Wharfedale Diamond 12.4 and DALI Oberon 7 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Diamond 12.4 features a 1" Textile Soft-Dome Tweeter and 2 x 6.5" Mica-infused polypropylene Woofer with a Crossover frequency at 2100Hz. On the other hand, the Oberon 7 features a 1.125" Soft-Dome Tweeter and 2 x 7" Wood Fiber Woofer with a Crossover frequency at 2300Hz.
Frequency Response
Diamond 12.4 has a frequency range of 40-20k Hz whereas Oberon 7 has a frequency range of 36-26k Hz. With a minimum frequency of 36Hz, the Oberon 7 can go slightly deeper then the Diamond 12.4's min frequency of 40Hz.
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
Diamond 12.4 is a 8 ohms speaker compared to the Oberon 7 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Diamond 12.4 sensitivity is rated at 89 dB and the Oberon 7's is rated at 88.5 dB.

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.
Diamond 12.4 can handle a max power of 200 watts RMS from the amp the whereas Oberon 7 has a max power handling value of 180 watts RMS, 20 watts less than the Diamond 12.4.
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
Diamond 12.4 features Binding post posts which make bi-amping or bi-wiring possible. Oberon 7 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Diamond 12.4 and Oberon 7 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 Wharfedale Diamond 12.4's and DALI Oberon 7's external dimensions. Wharfedale Diamond 12.4 has external dimensions of 1156.0 x 200.0 x 388.0mm ( 45-1/2 x 8 x 15-1/4inch) whereas DALI Oberon 7 has external dimensions of 1016.0 x 200.0 x 329.0mm ( 40 x 7-7/8 x 12-15/16inch) .
Below you can see the front view size comparison of Wharfedale Diamond 12.4 and DALI Oberon 7 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 Wharfedale Diamond 12.4 is approximately 776.0cm2 / 120.3inch2 and base area of the DALI Oberon 7 is approximately 658.0cm2 / 102.0inch2. The Diamond 12.4 requires 18% more surface area than the Oberon 7 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 Wharfedale Diamond 12.4 weighs 22.40kg / 49.3lbs and the DALI Oberon 7 weighs 14.80kg / 32.6lbs. This makes the Diamond 12.4 51% heavier than the Oberon 7.
