Ai61 and Ai81 are members of Fluance's Ai series of speakers. Below you can find the loudspeakers from this series.
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Ai61 and Ai81 are 2-way speakers.

Ai61 features a 1" Silk Neodymium Ferrofluid Cooled Soft Dome Tweeter and 1 x 6.5" Woven, Glass Fiber Composite Woofer. On the other hand, the Ai81 features a 1" Silk Neodymium Ferrofluid Cooled Soft Dome Tweeter and 2 x 6.5" Woven, Glass Fiber Composite Woofer.
Frequency Response
Ai61 has a frequency range of 32-20k Hz whereas Ai81 has a frequency range of 30-20k Hz. With a minimum frequency of 30Hz, the Ai81 can go slightly deeper then the Ai61's min frequency of 32Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Ai81 can handle a max power of 150 watts RMS, whereas Ai61 has a max power handling value of 120 watts RMS, 30 watts less than the Ai81.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Cabinet Type and Port Position
Ai61 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 Ai61 with its rear-firing port.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Fluance Ai61's and Fluance Ai81's external dimensions. Fluance Ai61 has external dimensions of 33.3 x 19.8 x 23.4 cm (13.1 x 7.8 x 9.2 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 18mm wider, 627mm taller and 26mm deeper than Fluance Ai61.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Fluance Ai81 needs about 21% more floor or shelf area. Fluance Ai81 is 26mm deeper, so it stands that much further out from the wall. Fluance Ai81 is 627mm taller.
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 Ai61 is approximately 463.0cm2 / 71.8inch2 and base area of the Fluance Ai81 is approximately 561.0cm2 / 87.0inch2. The Ai61 requires 17% less surface area than the Ai81 which gives it a small advantage on placement in tight spaces.
