What size room are the AE100 Mark II and Klipsch RP-600M 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* AE100 Mark II Klipsch RP-600M
Near-field Poor Average
Small Room Average Good
Mid-size Room Good Average
Large Room Average Poor
Very Large Room Poor Bad

(* 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.)

In the following sections, we will get into more detail in order to better understand how the AE100 Mark II and Klipsch RP-600M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

AE100 MII features a 1" fabric soft dome with waveguide Tweeter and 1 x 5.2" paper cone Woofer with a Crossover frequency at 2900Hz. On the other hand, the RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.

Frequency Response

AE100 MII has a frequency range of 51Hz - 26kHz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the AE100 MII's min frequency of 51Hz.

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 Bookshelf class in our database.

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

AE100 MII is a 6 ohms speaker compared to the RP-600M which has a nominal impedance of 8 ohms.

These two speakers also have different sensitivity levels. AE100 MII sensitivity is rated at 87 dB and the RP-600M's is rated at 96 dB. This 9 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to AE100 Mark II, 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.

AE100 MII can handle a max power of 120 watts RMS from the amp the whereas RP-600M has a max power handling value of 100 watts RMS, 20 watts less than the AE100 MII.

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 AE100 MII and RP-600M 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 AE100 Mark II's and Klipsch RP-600M's external dimensions. AE100 Mark II has external dimensions of 290.0 x 165.0 x 250.0mm ( 11.4 x 6.5 x 9.8inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .

Klipsch RP-600M is clearly the larger of the two speakers. Its body is 37mm wider, 109mm taller and 51mm deeper than AE100 Mark II.

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 AE100 Mark II is approximately 412.5cm2 / 63.9inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The AE100 MII requires 32% less surface area than the RP-600M 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 AE100 Mark II weighs 4.60kg / 10.1lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the RP-600M 59% heavier than the AE100 MII.

Here is a comparison of how AE100 MII and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
