In this review, we will be comparing Tales 340 and KUBE 8b, two Powered Subwoofer speakers from Triangle and KEF. 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 Tales 340 and KEF KUBE 8b 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 Tales 340 and KEF KUBE 8b 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 Tales 340and KEF KUBE 8b have a single woofer setup however the Triangle Tales 340's woofer is 10-inch whereas the KEF KUBE 8b features a 8-inch woofer.
Frequency Response
Tales 340 has a frequency range of 30-120 Hz whereas KUBE 8b has a frequency range of 34-140 Hz. With a minimum frequency of 30Hz, the Tales 340 can go slightly deeper then the KUBE 8b's min frequency of 34Hz.
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 Tales 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 KEF KUBE 8b 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 Tales 340's and KEF KUBE 8b's external dimensions. Triangle Tales 340 has external dimensions of 383.0 x 342.0 x 357.0mm ( 15-1/16 x 13-7/16 x 14-1/16inch) 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) .
Triangle Tales 340 is clearly the larger of the two speakers. Its body is 46mm wider, 89mm taller and 18mm deeper than KEF KUBE 8b.
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 Tales 340 is approximately 1220.9cm2 / 189.2inch2 and base area of the KEF KUBE 8b is approximately 1003.4cm2 / 155.5inch2. The Tales 340 requires 22% more surface area than the KUBE 8b which gives it a small disadvantage 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 Tales 340 weighs 8.90kg / 19.6lbs and the KEF KUBE 8b weighs 11.36kg / 25lbs. This makes the KUBE 8b 28% heavier than the Tales 340.
Here is a comparison of how Tales 340 and KUBE 8b's weights compare with the average, max and min weights in Powered Subwoofer class.
