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 Q Acoustics Q SUB80's and Q Acoustics Q SUB100's external dimensions. Q Acoustics Q SUB80 has external dimensions of 315.0 x 315.0 x 347.0mm ( 12-3/8 x 12-3/8 x 13-11/16inch) whereas Q Acoustics Q SUB100 has external dimensions of 350.0 x 350.0 x 382.0mm ( 13-3/4 x 13-3/4 x 15-1/16inch) .

Q Acoustics Q SUB100 is clearly the larger of the two speakers. Its body is 35mm wider, 35mm taller and 35mm deeper than Q Acoustics Q SUB80.

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 Q Acoustics Q SUB80 is approximately 1093.1cm2 / 169.4inch2 and base area of the Q Acoustics Q SUB100 is approximately 1337.0cm2 / 207.2inch2. The Q SUB80 requires 18% less surface area than the Q SUB100 which gives it a small advantage on placement in tight spaces.

Weight Comparison

The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The Q Acoustics Q SUB80 weighs 15.00kg / 33lbs and the Q Acoustics Q SUB100 weighs 16.70kg / 36.7lbs. This makes the Q SUB100 11% heavier than the Q SUB80.
