Cabinet Type
The Klipsch R-101SW has a Bass Reflex type cabinet. 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. On the other hand the ELAC SUB3070 have Acoustic Suspension type enclosure. 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.
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 Klipsch R-101SW's and ELAC SUB3070's external dimensions. Klipsch R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm ( 14-9/16inch x 14-1/16inch x 20-13/16inch ) whereas ELAC SUB3070 has external dimensions of 435.0 x 520.0 x 477.0mm ( 17-1/8 x 20-7/16 x 18-3/4inch) .
Klipsch R-101SW is 162mm narrower and 65mm shorter than ELAC SUB3070 but it is also 52mm 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 Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2 and base area of the ELAC SUB3070 is approximately 2480.4cm2 / 384.5inch2. The R-101SW requires 24% less surface area than the SUB3070 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 Klipsch R-101SW weighs 13.91kg / 30.6lbs and the ELAC SUB3070 weighs 35.00kg / 77lbs. This makes the SUB3070 152% heavier than the R-101SW.
