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 Borea BR07 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 Borea BR07 has a front firing ports. Triangle Borea BR07'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 Triangle Borea BR07'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 Triangle Borea BR07 has external dimensions of 980.0 x 206.0 x 314.0mm ( 38.5 x 8.1 x 12.3inch) .

Triangle Borea BR07 is clearly the larger of the two speakers. Its body is 41mm wider, 120mm taller and 64mm 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 Triangle Borea BR07 is approximately 646.8cm2 / 100.3inch2. The AE109 MII requires 36% less surface area than the Borea BR07 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 Triangle Borea BR07 weighs 16.92kg / 37.2lbs. This makes the Borea BR07 6% heavier than the AE109 MII.

Here is a comparison of how AE109 MII and Borea BR07's weights compare with the average, max and min weights in Passive Floor-standing class.
