What size room are the AE109 Mark II and Jamo S 809 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* AE109 Mark II Jamo S 809
Near-field Bad Bad
Small Room Poor Poor
Mid-size Room Good Good
Large Room Good Good
Very Large Room Poor Poor

(* 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 AE109 Mark II and Jamo S 809 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 AE109 MII is a 3-way design whereas the S 809 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.

Driver Setup 3-way 2-way
Tweeter 1-inch 1-inch
Midrange 1 x 5.2-inch -
Woofer 1 x 5.2-inch 3 x 5-inch

AE109 MII features a 1" fabric dome with waveguide Tweeter , a 5.2" Midrange and 1 x 5.2" paper cone Woofer with a Crossover frequency at 275Hz and 2.5kHz. On the other hand, the S 809 features a 1" Tweeter and 3 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz.

Frequency Response

AE109 MII has a frequency range of 41Hz - 26kHz whereas S 809 has a frequency range of 37-26k Hz. With a minimum frequency of 37Hz, the S 809 can go slightly deeper then the AE109 MII's min frequency of 41Hz.

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.

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

AE109 MII is a 6 ohms speaker compared to the S 809 which has a nominal impedance of 8 ohms.

These two speakers also have different sensitivity levels. AE109 MII sensitivity is rated at 89 dB and the S 809's is rated at 90 dB. This 1 dB difference makes the Jamo S 809 a more sensitive speaker compared to AE109 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.

AE109 MII can handle a max power of 175 watts RMS from the amp the whereas S 809 has a max power handling value of 120 watts RMS, 55 watts less than the AE109 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

AE109 MII has a rear firing port whereas S 809 has a front firing ports. Jamo S 809's front-firing port gives more flexibility in placement in regards to proximity to walls compared to AE109 Mark II with its rear-firing port.

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 AE109 Mark II's and Jamo S 809's external dimensions. AE109 Mark II has external dimensions of 860.0 x 165.0 x 250.0mm ( 33.9 x 6.5 x 9.8inch) whereas Jamo S 809 has external dimensions of 1042.0 x 191.0 x 252.0mm ( 41.0 x 7.5 x 9.9inch) .

Jamo S 809 is clearly the larger of the two speakers. Its body is 26mm wider, 182mm taller and 2mm deeper than AE109 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 AE109 Mark II is approximately 412.5cm2 / 63.9inch2 and base area of the Jamo S 809 is approximately 481.3cm2 / 74.6inch2. The AE109 MII requires 14% less surface area than the S 809 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 AE109 Mark II weighs 16.00kg / 35.2lbs and the Jamo S 809 weighs 13.60kg / 29.9lbs. This makes the AE109 MII 18% heavier than the S 809.

Here is a comparison of how AE109 MII and S 809's weights compare with the average, max and min weights in Passive Floor-standing class.
