Cabinet Type
The Buchardt SUB10 has a Acoustic Suspension type cabinet. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs. On the other hand the Klipsch SPL-120 have Bass Reflex type enclosure. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs.
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 Buchardt SUB10's and Klipsch SPL-120's external dimensions. Buchardt SUB10 has external dimensions of 490 x 320 x 160 mm ( 19.3 x 12.6 x 6.3 inch) whereas Klipsch SPL-120 has external dimensions of 450.0 x 375.0 x 540.0mm ( 17-11/16 x 14-3/4 x 21-1/4inch) .
Buchardt SUB10 is 55mm narrower and 380mm less deeper than Klipsch SPL-120 but it is also 40mm 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 Buchardt SUB10 is approximately 512.0cm2 / 79.4inch2 and base area of the Klipsch SPL-120 is approximately 2025.0cm2 / 313.9inch2. The SUB10 requires 75% less surface area than the SPL-120 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 Buchardt SUB10 weighs 14.00kg / 30.8lbs and the Klipsch SPL-120 weighs 20.45kg / 45lbs. This makes the SPL-120 46% heavier than the SUB10.
Here is a comparison of how SUB10 and SPL-120's weights compare with the average, max and min weights in Powered Subwoofer class.
