What size room are the Q Acoustics 5040 and Jamo C 97 II 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:

Drivers
One of the fundamental differences between these two speakers is that 5040 is a 2-way design whereas the C 97 II is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

5040 features a 1" Soft-dome Tweeter and 2 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz. On the other hand, the C 97 II features a 1" Tweeter, a 6" Midrange and 3 x 6" Composite Woofer.
Frequency Response
5040 has a frequency range of 39-30k Hz whereas C 97 II has a frequency range of 32-24k Hz. With a minimum frequency of 32Hz, the C 97 II can go significantly deeper on the low side and provide stronger bass compared to the 5040's min frequency of 39Hz.
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
5040 and C 97 II have the same Impedance of 6 ohms but where they differ is the sensitivity levels. 5040 sensitivity is rated at 91.5 dB and the C 97 II's is at 89 dB. This 3 dB difference makes the Q Acoustics 5040 a more sensitive speaker compared to Jamo C 97 II, 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.
C 97 II can handle a max power of 180 watts RMS, whereas 5040 has a max power handling value of 150 watts RMS, 30 watts less than the C 97 II.
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.

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
C 97 II features Posts posts which make bi-amping or bi-wiring possible. 5040 has a Binding post which doesn't feature bi-amping/bi-wiring.

Jamo C 97 II's Posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 5040 and C 97 II 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 5040's and Jamo C 97 II's external dimensions. Q Acoustics 5040 has external dimensions of 969.0 x 362.0 x 293.0mm (38-1/8inch x 14-1/4inch x 11-1/2inch) whereas Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm (42-1/8 x 9-3/4 x 15-13/16inch).
Q Acoustics 5040 is 101mm shorter and 109mm less deeper than Jamo C 97 II but it is also 114mm wider.
Below you can see the front view size comparison of Q Acoustics 5040 and Jamo C 97 II 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 5040 is approximately 1060.7cm2 / 164.4inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The 5040 requires 6% more surface area than the C 97 II 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 Q Acoustics 5040 weighs 18.05kg / 39.7lbs and the Jamo C 97 II weighs 24.55kg / 54lbs. This makes the C 97 II 36% heavier than the 5040.

A generation apart: Q Acoustics 5040 is the newer design, against a 2016 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|

Jamo C 97 II digs deeper - 32Hz against 39Hz. A subwoofer would even that out. |
| Amplifier needs |
A |
Q Acoustics 5040 is more sensitive (92dB vs 89dB), so it goes louder on the same amplifier. |

A Q Acoustics 5040
B Jamo C 97 II
depends neither is better in the abstract - it turns on your room, placement 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?
Jamo C 97 II has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 39Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, Q Acoustics 5040 is the safer partner - the other will want more current or more watts to sound its best.
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.
