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:

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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Prime Tower can handle a max power of 250 watts RMS, whereas Oberon 7 has a max power handling value of 180 watts RMS, 70 watts less than the Prime Tower.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
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.
SVS Prime Tower's 5-Way post terminals
DALI Oberon 7's Post terminals
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
The size of a speaker can sometimes be 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.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | SVS Prime Tower digs deeper - 30Hz against 36Hz. A subwoofer would even that out. |
| Amplifier needs | B | DALI Oberon 7 is more sensitive (89dB vs 87dB), so it goes louder on the same amplifier. |
| Amplifier match | A | SVS Prime Tower is the easier load at 8 ohms. |
| Headroom | A | SVS Prime Tower takes more power (250W vs 180W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Price | A | SVS Prime Tower is cheaper - $1,400 against $1,700, about 18% less. |
A SVS Prime Tower B DALI Oberon 7
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS Prime Tower is the easier recommendation: it leads on most of the measured areas and costs less. Take DALI Oberon 7 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 36Hz anyway, so judge these on the other rows instead. Match it to your room: we rate SVS Prime Tower the better fit for a very large room, and DALI Oberon 7 for a mid-size room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
