In this review, we will be comparing Sub C-8 D and ForceField 4, two Powered Subwoofer speakers from DALI and GoldenEar. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of DALI Sub C-8 D and GoldenEar ForceField 4 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both DALI Sub C-8 Dand GoldenEar ForceField 4 have a single woofer setup however the DALI Sub C-8 D's woofer is 8-inch whereas the GoldenEar ForceField 4 features a 10-inch woofer.
Frequency Response
Sub C-8 D has a frequency range of 33-200 Hz whereas ForceField 4 has a frequency range of 14-250 Hz. With a minimum frequency of 14Hz, the ForceField 4 can go significantly deeper on the low side and provide stronger bass compared to the Sub C-8 D's min frequency of 33Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
The DALI Sub C-8 D 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 GoldenEar ForceField 4 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs.
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 DALI Sub C-8 D's and GoldenEar ForceField 4's external dimensions. DALI Sub C-8 D has external dimensions of 335 x 295 x 310 mm () whereas GoldenEar ForceField 4 has external dimensions of 331.0 x 340.0 x 482.0mm (13inch x 13-3/8inch x 18-15/16inch).
DALI Sub C-8 D is 45mm narrower and 172mm less deeper than GoldenEar ForceField 4 but it is also 4mm taller.
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.
GoldenEar ForceField 4 needs about 79% more floor or shelf area. GoldenEar ForceField 4 is 172mm deeper, so it stands that much further out from the wall.
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 DALI Sub C-8 D is approximately 914.5cm2 / 141.7inch2 and base area of the GoldenEar ForceField 4 is approximately 1638.8cm2 / 254.0inch2. The Sub C-8 D requires 44% less surface area than the ForceField 4 which gives it a small advantage on placement in tight spaces.
