In this review, we will be comparing Genelec G Three and Navis ARB-51, two Powered Bookshelf speakers from Genelec and ELAC. Being Powered speakers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them.

Drivers
One of the fundamental differences between these two speakers is that Genelec G Three is a 2-way design whereas the Navis ARB-51 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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 Genelec G Three and Navis ARB-51 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 Genelec G Three's and ELAC Navis ARB-51's external dimensions. Genelec G Three has external dimensions of 299 x 189 x 178 mm ( 11.8 x 7.4 x 7) whereas ELAC Navis ARB-51 has external dimensions of 350.8 x 192.1 x 287.3mm ( 13.8125 x 7.5625 x 11.3125inch) .
ELAC Navis ARB-51 is clearly the larger of the two speakers. Its body is 3.1mm wider, 51.8mm taller and 109.3mm deeper than Genelec G Three.

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 Genelec G Three is approximately 336.4cm2 / 52.1inch2 and base area of the ELAC Navis ARB-51 is approximately 551.9cm2 / 85.5inch2. The Genelec G Three requires 39% less surface area than the Navis ARB-51 which gives it a small advantage on placement in tight spaces.
