What size room are the DALI Spektor 6 and DALI Oberon 5 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:

Spektor 6 features a 1" Soft-Dome Tweeter and 2 x 6.5" Wood Fiber Woofer with a Crossover frequency at 2500Hz. On the other hand, the Oberon 5 features a 1.125" Soft-Dome Tweeter and 2 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2400Hz.
Frequency Response
Spektor 6 has a frequency range of 43-26k Hz whereas Oberon 5 has a frequency range of 39-26k Hz. With a minimum frequency of 39Hz, the Oberon 5 can go slightly deeper then the Spektor 6's min frequency of 43Hz.
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
Spektor 6 and Oberon 5 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Spektor 6 sensitivity is rated at 88.5 dB and the Oberon 5's is at 88 dB. This 1 dB difference makes the DALI Spektor 6 a more sensitive speaker compared to DALI Oberon 5, 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.
Spektor 6 and Oberon 5 have the same power range of 30-150 watts.
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
Spektor 6 features Post type posts and Oberon 5 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
DALI Oberon 5's Post terminals
Cabinet Type and Port Position
Both Spektor 6 and Oberon 5 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 DALI Spektor 6's and DALI Oberon 5's external dimensions. DALI Spektor 6 has external dimensions of 972.0 x 195.0 x 313.0mm (38.3 x 7.7 x 12.3inch) whereas DALI Oberon 5 has external dimensions of 832.0 x 202.0 x 277.0mm (32-3/4 x 7-15/16 x 10-7/8inch).
DALI Oberon 5 is 140mm shorter and 36mm less deeper than DALI Spektor 6 but it is also 7mm 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 DALI Spektor 6 is approximately 610.4cm2 / 94.6inch2 and base area of the DALI Oberon 5 is approximately 559.5cm2 / 86.7inch2. The Spektor 6 requires 9% more surface area than the Oberon 5 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 DALI Spektor 6 weighs 13.80kg / 30.4lbs and the DALI Oberon 5 weighs 10.80kg / 23.8lbs. This makes the Spektor 6 28% heavier than the Oberon 5.
Here is a comparison of how Spektor 6 and Oberon 5's weights compare with the average, max and min weights in Passive Floor-standing class.

Both are DALI, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | B | DALI Oberon 5 digs deeper - 39Hz against 43Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 88dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (150W vs 150W). |
| Size | depends | DALI Oberon 5 is easier to place; DALI Spektor 6 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. DALI Oberon 5 sits in a wider range (9 models), so a matched surround system is easier later. |
A DALI Spektor 6 B DALI Oberon 5
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?
DALI Oberon 5 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does.
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.
