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 KEF Kube 15 MIE's and SVS PB-2000 Pro's external dimensions. KEF Kube 15 MIE has external dimensions of 519 x 500 x 515 mm ( 20.4 x 19.7 x 20.3 in) whereas SVS PB-2000 Pro has external dimensions of 534.0 x 442.0 x 609.0mm ( 21 x 17-3/8 x 23-15/16inch) .
KEF Kube 15 MIE is 15mm shorter and 94mm less deeper than SVS PB-2000 Pro but it is also 58mm wider.
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 KEF Kube 15 MIE is approximately 2575.0cm2 / 399.1inch2 and base area of the SVS PB-2000 Pro is approximately 2691.8cm2 / 417.2inch2. The Kube 15 MIE requires 4% less surface area than the PB-2000 Pro 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 KEF Kube 15 MIE weighs 27.50kg / 60.5lbs and the SVS PB-2000 Pro weighs 29.45kg / 64.8lbs. This makes the PB-2000 Pro 7% heavier than the Kube 15 MIE.
