None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both Borea BR03 BT and YU4 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Borea BR03 BT's and Kanto YU4's external dimensions. Triangle Borea BR03 BT has external dimensions of 176 x 310 x 274 mm ( 6.92 x 12.2 x 10.8 inches) whereas Kanto YU4 has external dimensions of 220.0 x 140.0 x 190.0mm ( 8.7 x 5.5 x 7.5inch) .
Triangle Borea BR03 BT is clearly the larger of the two speakers. Its body is 36mm wider, 90mm taller and 84mm deeper than Kanto YU4.
Below you can see the front view size comparison of Triangle Borea BR03 BT and Kanto YU4 in scale.

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 Borea BR03 BT is approximately 482.0cm2 / 74.7inch2 and base area of the Kanto YU4 is approximately 266.0cm2 / 41.2inch2. The Borea BR03 BT requires 81% more surface area than the YU4 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Triangle Borea BR03 BT weighs 11.20kg / 24.6lbs and the Kanto YU4 weighs 2.50kg / 5.5lbs. This makes the Borea BR03 BT 348% heavier than the YU4.
