What size room are the Q Acoustics 5020 and Wharfedale Denton 85 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:

5020 features a 1" Soft-dome Tweeter and 1 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz. On the other hand, the Denton 85 features a 1" woven textile Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 3100Hz.
Frequency Response
5020 has a frequency range of 53-30k Hz whereas Denton 85 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Denton 85 can go significantly deeper on the low side and provide stronger bass compared to the 5020's min frequency of 53Hz.
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
5020 is a 6 ohms speaker compared to the Denton 85 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Denton 85 can provide this impedance level.
These two speakers also have different sensitivity levels. 5020 sensitivity is rated at 87.9 dB and the Denton 85's is rated at 88 dB.
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.
Denton 85 can handle a max power of 120 watts RMS, whereas 5020 has a max power handling value of 100 watts RMS, 20 watts less than the Denton 85.
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
Denton 85 features Post posts which make bi-amping or bi-wiring possible. 5020 has a Binding post which doesn't feature bi-amping/bi-wiring.

Wharfedale Denton 85's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 5020 and Denton 85 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 Q Acoustics 5020's and Wharfedale Denton 85's external dimensions. Q Acoustics 5020 has external dimensions of 286.0 x 181.0 x 293.0mm (11-1/4nch x 7-1/8inch x 11-1/2inch) whereas Wharfedale Denton 85 has external dimensions of 342.0 x 240.0 x 304.0mm (13-7/16 x 9-7/16 x 11-15/16inch).
Wharfedale Denton 85 is clearly the larger of the two speakers. Its body is 59mm wider, 56mm taller and 11mm deeper than Q Acoustics 5020.
Below you can see the front view size comparison of Q Acoustics 5020 and Wharfedale Denton 85 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 Q Acoustics 5020 is approximately 530.3cm2 / 82.2inch2 and base area of the Wharfedale Denton 85 is approximately 729.6cm2 / 113.1inch2. The 5020 requires 27% less surface area than the Denton 85 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 Q Acoustics 5020 weighs 7.00kg / 15.4lbs and the Wharfedale Denton 85 weighs 9.00kg / 19.8lbs. This makes the Denton 85 29% heavier than the 5020.

A generation apart: Q Acoustics 5020 is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | Wharfedale Denton 85 digs deeper - 45Hz against 53Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 88dB) - both want much the same power. |
| Amplifier match | A | Q Acoustics 5020 is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (100W vs 120W). |
| Size | depends | Q Acoustics 5020 is easier to place; Wharfedale Denton 85 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Wharfedale Denton 85: bi-amping. |
| Price | A | Q Acoustics 5020 is cheaper - $899 against $999, about 10% less. |
A Q Acoustics 5020 B Wharfedale Denton 85
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?
The usual trade-off: Wharfedale Denton 85 measures better, Q Acoustics 5020 costs about about 11% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 53Hz anyway, which makes the cheaper Q Acoustics 5020 much easier to justify. Match it to your room: we rate Q Acoustics 5020 the better fit for near-field listening and a small room, and Wharfedale Denton 85 for a mid-size room and a large 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.
