In this review, we will be comparing Q Acoustics 5090 and RP-600C, two Passive Center Channel speakers from Q Acoustics and Klipsch. Let's have a brief look at the main features
of Q Acoustics 5090 and Klipsch RP-600C first before getting into our more
detailed comparison.
What size room are the Q Acoustics 5090 and Klipsch RP-600C 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:
In the following sections, we will get into more detail in order to better understand how the Q Acoustics 5090 and Klipsch RP-600C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Q Acoustics 5090 features a 1" Soft-dome Tweeter and 2 x 4.5" Continuous Curved Cone Woofer with a Crossover frequency at 2100 Hz. On the other hand, the RP-600C features a 1" titanium Tractrix horn dome Tweeter and 2 x 6.5" Cerametallic cone Woofer .
Frequency Response
Q Acoustics 5090 has a frequency range of 57-30k Hz whereas RP-600C has a frequency range of 58-25k Hz. With a minimum frequency of 57Hz, the Q Acoustics 5090 can go slightly deeper then the RP-600C's min frequency of 58Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Center Channel class in our database.

High Frequency
Center Channel Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Q Acoustics 5090 is a 6 ohms speaker compared to the RP-600C which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Q Acoustics 5090 sensitivity is rated at 90.5 dB and the RP-600C's is rated at 97 dB. This 6 dB difference makes the Klipsch RP-600C a more sensitive speaker compared to Q Acoustics 5090, 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. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Q Acoustics 5090 can handle a max power of 150 watts RMS from the amp the whereas RP-600C has a max power handling value of 125 watts RMS, 25 watts less than the Q Acoustics 5090.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Q Acoustics 5090 features Binding post type posts and RP-600C has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Q Acoustics 5090 and RP-600C 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
Size of a speaker can sometimes become 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 5090's and Klipsch RP-600C's external dimensions. Q Acoustics 5090 has external dimensions of 166.0 x 431.0 x 245.0mm ( 6-1/2inch x 16-15/16inch x 9-5/8inch ) whereas Klipsch RP-600C has external dimensions of 204.0 x 558.0 x 308.0mm ( 8 x 21-15/16 x 12-1/8inch) .
Klipsch RP-600C is clearly the larger of the two speakers. Its body is 127mm wider, 38mm taller and 63mm deeper than Q Acoustics 5090.
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 5090 is approximately 1056.0cm2 / 163.7inch2 and base area of the Klipsch RP-600C is approximately 1718.6cm2 / 266.4inch2. The Q Acoustics 5090 requires 39% less surface area than the RP-600C which gives it a small advantage 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 5090 weighs 8.50kg / 18.7lbs and the Klipsch RP-600C weighs 10.91kg / 24lbs. This makes the RP-600C 28% heavier than the Q Acoustics 5090.
Here is a comparison of how Q Acoustics 5090 and RP-600C's weights compare with the average, max and min weights in Passive Center Channel class.
