In this review, we will be comparing Thetis 300 and ASW610, two Powered Subwoofer speakers from Triangle and Bowers Wilkins. 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 300 and B&W ASW610 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 300 and B&W ASW610 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.Both Triangle Thetis 300and B&W ASW610 have a single woofer setup however the Triangle Thetis 300's woofer is 8-inch whereas the B&W ASW610 features a 10-inch woofer.
Frequency Response
Thetis 300 has a frequency range of 32-120 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 27Hz, the ASW610 can go significantly deeper on the low side and provide stronger bass compared to the Thetis 300's min frequency of 32Hz.
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 300 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 B&W ASW610 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 Triangle Thetis 300's and B&W ASW610's external dimensions. Triangle Thetis 300 has external dimensions of 340.0 x 300.0 x 300.0mm ( 13-3/8 x 11-13/16 x 11-13/16inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm ( 12-5/8 x 12-1/4 x 15-1/2inch) .
Triangle Thetis 300 is 12mm narrower and 94mm less deeper than B&W ASW610 but it is also 19mm 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 Triangle Thetis 300 is approximately 900.0cm2 / 139.5inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Thetis 300 requires 27% less surface area than the ASW610 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 300 weighs 10.60kg / 23.3lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the ASW610 18% heavier than the Thetis 300.
Here is a comparison of how Thetis 300 and ASW610's weights compare with the average, max and min weights in Powered Subwoofer class.
