What size room are the AE307 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:

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.)
In the following sections, we will get into more detail in order to better understand how the AE307 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.

AE307 features a 1.1" aluminium dome with waveguide Tweeter and 2 x 5.2" ceramic aluminium sandwich Woofer with a Crossover frequency at 2560Hz. 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
AE307 has a frequency range of 42Hz - 30kHz whereas RP-600C has a frequency range of 58-25k Hz. With a minimum frequency of 42Hz, the AE307 can go significantly deeper on the low side and provide stronger bass compared to 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
AE307 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. AE307 sensitivity is rated at 89 dB and the RP-600C's is rated at 97 dB. This 8 dB difference makes the Klipsch RP-600C a more sensitive speaker compared to AE307, 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.
AE307 can handle a max power of 175 watts RMS from the amp the whereas RP-600C has a max power handling value of 125 watts RMS, 50 watts less than the AE307.
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.
Cabinet Type and Port Position
Both AE307 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 AE307's and Klipsch RP-600C's external dimensions. AE307 has external dimensions of 175.0 x 460.0 x 260.0mm ( 6.9 x 18.1 x 10.2inch) 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 98mm wider, 29mm taller and 48mm deeper than AE307.
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 AE307 is approximately 1196.0cm2 / 185.4inch2 and base area of the Klipsch RP-600C is approximately 1718.6cm2 / 266.4inch2. The AE307 requires 30% less surface area than the RP-600C which gives it a small advantage on placement in tight spaces.
