In this review, we will be comparing Prime Tower and Oberon 7, two Passive Floor-standing speakers from SVS and DALI. Let's have a brief look at the main features
of SVS Prime Tower and DALI Oberon 7 first before getting into our more
detailed comparison.
What size room are the SVS Prime Tower 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 SVS Prime Tower 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.

Drivers
One of the fundamental differences between these two speakers is that Prime Tower is a 3-way design whereas the Oberon 7 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Prime Tower features a 1" aluminum dome Tweeter , a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 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
Prime Tower has a frequency range of 30-25k Hz whereas Oberon 7 has a frequency range of 36-26k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the Oberon 7's min frequency of 36Hz.
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.

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
Prime Tower 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. Prime Tower sensitivity is rated at 87 dB and the Oberon 7's is rated at 88.5 dB. This 2 dB difference makes the DALI Oberon 7 a more sensitive speaker compared to SVS Prime Tower, 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.
Prime Tower can handle a max power of 250 watts RMS from the amp the whereas Oberon 7 has a max power handling value of 180 watts RMS, 70 watts less than the Prime Tower.
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
Prime Tower features Post type posts and Oberon 7 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Prime Tower 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 SVS Prime Tower's and DALI Oberon 7's external dimensions. SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm ( 36-5/8 x 8 x 11-11/16inch) 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) .
SVS Prime Tower is 85mm shorter and 32mm less deeper than DALI Oberon 7 but it is also 4mm wider.

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 SVS Prime Tower is approximately 605.9cm2 / 93.9inch2 and base area of the DALI Oberon 7 is approximately 658.0cm2 / 102.0inch2. The Prime Tower requires 8% less surface area than the Oberon 7 which gives it a small advantage 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 SVS Prime Tower weighs 18.23kg / 40.1lbs and the DALI Oberon 7 weighs 14.80kg / 32.6lbs. This makes the Prime Tower 23% heavier than the Oberon 7.
Here is a comparison of how Prime Tower and Oberon 7's weights compare with the average, max and min weights in Passive Floor-standing class.
