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.
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.
Ai41 can handle a max power of 150 watts RMS from the amp the whereas Ai41 has a max power handling value of 90 watts RMS , 60 watts less than the Ai81.
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
Ai41 has a rear firing port whereas Ai81 has a bottom firing ports. Fluance Ai81's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Fluance Ai41 with its rear-firing port.
Physical Specs

In this section, we are going to compare Fluance Ai41's and Fluance Ai81's external dimensions. Fluance Ai41 has external dimensions of 27.7 x 16.5 x 19.3 cm ( 10.9 x 6.5 x 7.6 inches) whereas Fluance Ai81 has external dimensions of 96 x 21.6 x 26 cm ( 37.8 x 8.50 x 10.24 inches) .
Fluance Ai81 is clearly the larger of the two speakers. Its body is 51mm wider, 683mm taller and 67mm deeper than Fluance Ai41.
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 Fluance Ai41 is approximately 318.0cm2 / 49.3inch2 and base area of the Fluance Ai81 is approximately 561.0cm2 / 87.0inch2. The Ai41 requires 43% less surface area than the Ai81 which gives it a small advantage on placement in tight spaces.
