What size room are the DALI Spektor 6 and DALI Oberon 3 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:

Listening Environment*	DALI Spektor 6	DALI Oberon 3
Near-field	Bad	Poor
Small Room	Poor	Average
Mid-size Room	Good	Good
Large Room	Good	Average
Very Large Room	Poor	Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m², Mid-size: 100-220 sq. ft / 9-20 m², Large 220-400 sq. ft / 20-36 m², Very Large: > 400 sq. ft / 36 m². 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

Both Spektor 6 and Oberon 3 are 2-way speakers.

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 3 features a 1.125" Soft-Dome Tweeter and 1 x 7" Wood Fiber Woofer with a Crossover frequency at 2400Hz.

Frequency Response

Spektor 6 has a frequency range of 43-26k Hz whereas Oberon 3 has a frequency range of 47-26k Hz. With a minimum frequency of 43Hz, the Spektor 6 can go slightly deeper then the Oberon 3's min frequency of 47Hz.

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.

Average

Median

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 3 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 3's is at 87 dB. This 2 dB difference makes the DALI Spektor 6 a more sensitive speaker compared to DALI Oberon 3, 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. Staying within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.

Both handle the same maximum of 150 watts RMS, though Spektor 6 is rated 30-150 watts and Oberon 3 25-150 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.

Cabinet Type and Port Position

Both Spektor 6 and Oberon 3 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 3'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 3 has external dimensions of 350.0 x 201.0 x 310.0mm (13-3/4 x 7-7/8 x 12-3/16inch).

Verdict

A floor-standing against a bookshelf. They are built for different places in a room, so start with where these have to go rather than which looks better on paper.

Area	Better	Why
Bass	A	DALI Spektor 6 digs deeper - 43Hz against 47Hz. A subwoofer would even that out.
Amplifier needs	A	DALI Spektor 6 is more sensitive (89dB vs 87dB), so it goes louder on the same amplifier.
Headroom	evenly matched	Similar power handling (150W vs 150W).
Size	depends	DALI Oberon 3 is easier to place; DALI Spektor 6 is bigger, which usually goes with fuller bass. Your room decides.
Type	depends	A Passive Floor-standing against a Passive Bookshelf - a different job rather than a better one.
Expandability	depends	Neither adds bi-amping, a sub output or height drivers. DALI Oberon 3 sits in a wider range (9 models), so a matched surround system is easier later.

A DALI Spektor 6 B DALI Oberon 3
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 Spektor 6 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Match it to your room: we rate DALI Spektor 6 the better fit for a large room, and DALI Oberon 3 for a small room. In a large or open-plan room, DALI Spektor 6 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, DALI Oberon 3 is the easier speaker to get right.

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.
