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 Yamaha NS-SW100's and Jamo S 808 SUB's external dimensions. Yamaha NS-SW100 has external dimensions of 352.4 x 352.4 x 409.6mm (13.875 x 13.875 x 16.125inch) whereas Jamo S 808 SUB has external dimensions of 459.0 x 178.0 x 356.0mm (18-1/16 x 7 x 14inch).
Jamo S 808 SUB is 174.4mm narrower and 53.6mm less deeper than Yamaha NS-SW100 but it is also 106.6mm 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 Yamaha NS-SW100 is approximately 1443.4cm2 / 223.7inch2 and base area of the Jamo S 808 SUB is approximately 633.7cm2 / 98.2inch2. The NS-SW100 requires 128% more surface area than the S 808 SUB which gives it a small disadvantage 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 Yamaha NS-SW100 weighs 12.02kg / 26.4lbs and the Jamo S 808 SUB weighs 8.64kg / 19lbs. This makes the NS-SW100 39% heavier than the S 808 SUB.
