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 Kanto ORA4 and Kanto REN 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 Kanto ORA4's and Kanto REN's external dimensions. Kanto ORA4 has external dimensions of 210.82 x 119.38 x 182.88mm ( 8.3inch x 4.7inch x 7.2inch ) whereas Kanto REN has external dimensions of 222.25 x 139.7 x 190.5mm ( 8.75inch x 5.5inch x 7.5inch ) .
Kanto REN is clearly the larger of the two speakers. Its body is 21mm wider, 11mm taller and 7mm deeper than Kanto ORA4.
Below you can see the front view size comparison of Kanto ORA4 and Kanto REN 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 Kanto ORA4 is approximately 217.8cm2 / 33.8inch2 and base area of the Kanto REN is approximately 266.0cm2 / 41.2inch2. The Kanto ORA4 requires 18% less surface area than the Kanto REN which gives it a small advantage 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 of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Kanto ORA4 weighs 1.80kg / 4lbs and the Kanto REN weighs 3.90kg / 8.6lbs. This makes the Kanto REN 117% heavier than the Kanto ORA4.
