In this review, we will be comparing Thetis 340 and ForceField 4, two Powered Subwoofer speakers from Triangle 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 Triangle Thetis 340 and GoldenEar ForceField 4 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Triangle Thetis 340 and GoldenEar ForceField 4 compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Triangle Thetis 340and GoldenEar ForceField 4 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Thetis 340 has a frequency range of 25-120 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 Thetis 340's min frequency of 25Hz.
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 Triangle Thetis 340 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
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 Triangle Thetis 340's and GoldenEar ForceField 4's external dimensions. Triangle Thetis 340 has external dimensions of 380.0 x 340.0 x 340.0mm ( 14-15/16 x 13-3/8 x 13-3/8inch) 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 ) .
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 Triangle Thetis 340 is approximately 1156.0cm2 / 179.2inch2 and base area of the GoldenEar ForceField 4 is approximately 1638.8cm2 / 254.0inch2. The Thetis 340 requires 29% less surface area than the ForceField 4 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 Triangle Thetis 340 weighs 16.10kg / 35.4lbs and the GoldenEar ForceField 4 weighs 14.55kg / 32lbs. This makes the Thetis 340 11% heavier than the ForceField 4.
Here is a comparison of how Thetis 340 and ForceField 4's weights compare with the average, max and min weights in Powered Subwoofer class.
