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 SVS 3000 In wall Single Subwoofer System's and KEF KUBE 8b's external dimensions. SVS 3000 In wall Single Subwoofer System has external dimensions of 635.0 x 305.1 x 94.7mm () whereas KEF KUBE 8b has external dimensions of 294.0 x 296.0 x 339.0mm (11-9/16 x 11-5/8 x 13-5/16inch).
KEF KUBE 8b is 9.1mm narrower and 341mm shorter than SVS 3000 In wall Single Subwoofer System but it is also 244.3mm deeper.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
KEF KUBE 8b needs about 247% more floor or shelf area. KEF KUBE 8b is 244mm deeper, so it stands that much further out from the wall. SVS 3000 In wall Single Subwoofer System is 341mm 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 SVS 3000 In wall Single Subwoofer System is approximately 288.9cm2 / 44.8inch2 and base area of the KEF KUBE 8b is approximately 1003.4cm2 / 155.5inch2. The 3000 In wall Single Subwoofer System requires 71% less surface area than the KUBE 8b which gives it a small advantage on placement in tight spaces.
