Mission QX-12SUB MKII has external dimensions of 478.0 x 400.0 x 465.0mm ( 18-13/16 x 15-3/4 x 18-5/16inch) whereas Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm ( 16-7/16 x 14-1/16 x 18-13/16inch) .
Klipsch SPL-100 is 42mm narrower and 60mm shorter than Mission QX-12SUB MKII but it is also 13mm deeper.
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 Mission QX-12SUB MKII is approximately 1860.0cm2 / 288.3inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The QX-12SUB MKII requires 9% more surface area than the SPL-100 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 Mission QX-12SUB MKII weighs 23.00kg / 50.6lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the QX-12SUB MKII 37% heavier than the SPL-100.
