What size room are the Wharfedale D320 and Focal Aria 906 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:

D320 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer. On the other hand, the Aria 906 features a 1" TNF aluminum/magnesium Inverted Hard Dome Tweeter and 1 x 6.5" Flax Woofer with a Crossover frequency at 2800Hz.
Frequency Response
D320 has a frequency range of 56-20k Hz whereas Aria 906 has a frequency range of 55-28k Hz. With a minimum frequency of 55Hz, the Aria 906 can go slightly deeper then the D320's min frequency of 56Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
D320 and Aria 906 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D320 sensitivity is rated at 87 dB and the Aria 906's is at 89.5 dB. This 3 dB difference makes the Focal Aria 906 a more sensitive speaker compared to Wharfedale D320, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
Aria 906 can handle a max power of 120 watts RMS, whereas D320 has a max power handling value of 100 watts RMS, 20 watts less than the Aria 906.
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
D320 features Binding post type posts and Aria 906 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Focal Aria 906's Binding post terminals
Cabinet Type and Port Position
D320 has a bottom firing port whereas Aria 906 has a rear firing ports. Wharfedale D320's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Focal Aria 906 with its rear-firing port.
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 Wharfedale D320's and Focal Aria 906's external dimensions. Wharfedale D320 has external dimensions of 321.0 x 181.0 x 277.0mm (12-5/8 x 7-1/8 x 10-7/8inch) whereas Focal Aria 906 has external dimensions of 391.0 x 228.0 x 288.0mm (15-3/8 x 8-15/16 x 11-5/16inch).
Focal Aria 906 is clearly the larger of the two speakers. Its body is 47mm wider, 70mm taller and 11mm deeper than Wharfedale D320.
Below you can see the front view size comparison of Wharfedale D320 and Focal Aria 906 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 D320 is approximately 501.4cm2 / 77.7inch2 and base area of the Focal Aria 906 is approximately 656.6cm2 / 101.8inch2. The D320 requires 24% less surface area than the Aria 906 which gives it a small advantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 D320 weighs 6.02kg / 13.2lbs and the Focal Aria 906 weighs 8.64kg / 19lbs. This makes the Aria 906 44% heavier than the D320.

These sit in different price classes - Focal Aria 906 costs roughly 8.8x what Wharfedale D320 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (56Hz vs 55Hz). |
| Amplifier needs | B | Focal Aria 906 is more sensitive (90dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (100W vs 120W). |
| Size | depends | Wharfedale D320 is easier to place; Focal Aria 906 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. Focal Aria 906 sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | A | Wharfedale D320 is cheaper - $249 against $2,198, about 89% less; arguably a different class. |
A Wharfedale D320 B Focal Aria 906
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?
Focal Aria 906 is ahead, but only on 1 of the measured areas, and it costs about 8.8x the price. That is a lot of money for a narrow margin on paper - Wharfedale D320 looks like the sensible buy unless something else about the Focal Aria 906 appeals to you. Match it to your room: we rate Wharfedale D320 the better fit for near-field listening and a small room, and Focal Aria 906 for a mid-size room and a large room. In a large or open-plan room, Focal Aria 906 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Wharfedale D320 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.
