What size room are the AE320 and AE309 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* AE320 AE309
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 AE320 and AE309 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers

Both AE320 and AE309 are 3-way speakers.

Tweeter 1.1-inch 1.1-inch
Midrange 1 x 5.2-inch 1 x 5.2-inch
Woofer 2 x 5.2-inch 1 x 5.2-inch

AE320 features a 1.1" aluminium dome with waveguide Tweeter , a 5.2" Midrange and 2 x 5.2" ceramic aluminium sandwich Woofer with a Crossover frequency at 380Hz and 3400Hz. On the other hand, the AE309 features a 1.1" aluminium dome with waveguide Tweeter , a 5.2" Midrange and 1 x 5.2" ceramic aluminium sandwich Woofer with a Crossover frequency at 296Hz and 2560Hz.

Frequency Response

AE320 has a frequency range of 35Hz - 30kHz whereas AE309 has a frequency range of 38Hz - 30kHz. With a minimum frequency of 35Hz, the AE320 can go slightly deeper then the AE309's min frequency of 38Hz.

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

AE320 is a 8 ohms speaker compared to the AE309 which has a nominal impedance of 6 ohms.

These two speakers also have different sensitivity levels. AE320 sensitivity is rated at 90 dB and the AE309's is rated at 89 dB. This 1 dB difference makes the AE320 a more sensitive speaker compared to AE309, 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.

AE320 can handle a max power of 200 watts RMS from the amp the whereas AE309 has a max power handling value of 175 watts RMS, 25 watts less than the AE320.

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 AE320 and AE309 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 AE320's and AE309's external dimensions. AE320 has external dimensions of 1000.0 x 175.0 x 260.0mm ( 39.4 x 6.9 x 10.2inch) whereas AE309 has external dimensions of 900.0 x 175.0 x 260.0mm ( 35.4 x 6.9 x 10.2inch) .

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 AE320 is approximately 455.0cm2 / 70.5inch2 and base area of the AE309 is approximately 455.0cm2 / 70.5inch2.

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 AE320 weighs 26.00kg / 57.2lbs and the AE309 weighs 22.00kg / 48.4lbs. This makes the AE320 18% heavier than the AE309.

Here is a comparison of how AE320 and AE309's weights compare with the average, max and min weights in Passive Floor-standing class.
