What size room are the AE520 and Klipsch RP-6000F 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:

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.)
In the following sections, we will get into more detail in order to better understand how the AE520 and Klipsch RP-6000F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that AE520 is a 3-way design whereas the RP-6000F is a 2-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.

AE520 features a 1" carbon fibre dome with waveguide Tweeter , a 5.2" Midrange and 4 x 5" carbon fibre cone Woofer with a Crossover frequency at 373Hz and 2.8kHz. On the other hand, the RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer .
Frequency Response
AE520 has a frequency range of 30Hz - 28kHz whereas RP-6000F has a frequency range of 34-25k Hz. With a minimum frequency of 30Hz, the AE520 can go slightly deeper then the RP-6000F's min frequency of 34Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing 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
AE520 is a 6 ohms speaker compared to the RP-6000F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AE520 sensitivity is rated at 90 dB and the RP-6000F's is rated at 97 dB. This 7 dB difference makes the Klipsch RP-6000F a more sensitive speaker compared to AE520, 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.
AE520 can handle a max power of 300 watts RMS from the amp the whereas RP-6000F has a max power handling value of 125 watts RMS, 175 watts less than the AE520.
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 AE520 and RP-6000F 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 AE520's and Klipsch RP-6000F's external dimensions. AE520 has external dimensions of 1130.0 x 185.0 x 320.0mm ( 44.5 x 7.3 x 12.6inch) whereas Klipsch RP-6000F has external dimensions of 1010.0 x 237.0 x 432.0mm ( 39-3/4 x 9-5/16 x 17inch) .
AE520 is 52mm narrower and 112mm less deeper than Klipsch RP-6000F but it is also 120mm taller.
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 AE520 is approximately 592.0cm2 / 91.8inch2 and base area of the Klipsch RP-6000F is approximately 1023.8cm2 / 158.7inch2. The AE520 requires 42% less surface area than the RP-6000F which gives it a small advantage on placement in tight spaces.
