What size room are the Q Acoustics 5020 and Q Acoustics 3020i 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* Q Acoustics 5020 Q Acoustics 3020i
Near-field Average Good
Small Room Good Good
Mid-size Room Average Average
Large Room Poor Poor
Very Large Room Bad No way

(* 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.)

Frequency Response

5020 has a frequency range of 53-30k Hz whereas 3020i has a frequency range of 64-30k Hz. With a minimum frequency of 53Hz, the 5020 can go significantly deeper on the low side and provide stronger bass compared to the 3020i's min frequency of 64Hz.

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.

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 and 3020i have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 5020 sensitivity is rated at 87.9 dB and the 3020i's is at 88 dB.

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.

5020 can handle a max power of 100 watts RMS, whereas 3020i has a max power handling value of 75 watts RMS, 25 watts less than the 5020.

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

5020 features Binding post type posts and 3020i has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both 5020 and 3020i 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 Q Acoustics 3020i'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 Q Acoustics 3020i has external dimensions of 278.0 x 170.0 x 282.0mm (10.9 x 6.6 x 11.1inch).

Q Acoustics 5020 is clearly the larger of the two speakers. Its body is 11mm wider, 8mm taller and 11mm deeper than Q Acoustics 3020i.

Below you can see the front view size comparison of Q Acoustics 5020 and Q Acoustics 3020i 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 Q Acoustics 3020i is approximately 479.4cm2 / 74.3inch2. The 5020 requires 11% more surface area than the 3020i which gives it a small disadvantage 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 Q Acoustics 3020i weighs 4.80kg / 10.6lbs. This makes the 5020 46% heavier than the 3020i.

Here is a comparison of how 5020 and 3020i's weights compare with the average, max and min weights in Passive Bookshelf class.

Verdict

These sit in different price classes - Q Acoustics 5020 costs roughly 2.3x what Q Acoustics 3020i does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.

AreaBetterWhy
BassAQ Acoustics 5020 digs deeper - 53Hz against 64Hz.
Amplifier needsevenly matchedSimilar sensitivity (88dB vs 88dB) - both want much the same power.
HeadroomAQ Acoustics 5020 takes more power (100W vs 75W) - more in hand in a big room.
SizedependsSimilar cabinet size - neither is easier to fit.
PriceBQ Acoustics 3020i is cheaper - $399 against $899, about 56% less; arguably a different class.

A Q Acoustics 5020  B Q Acoustics 3020i
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: Q Acoustics 5020 measures better, Q Acoustics 3020i costs about about 125% 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 64Hz anyway, which makes the cheaper Q Acoustics 3020i much easier to justify. Match it to your room: we rate Q Acoustics 3020i the better fit for near-field listening; elsewhere the two are rated the same.

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.
