Drivers

One of the fundamental differences between these two speakers is that Genelec G Four 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.

Driver Genelec G Four ELAC Navis ARB-51
Driver Setup 2-way 3-way
Tweeter 0.75-inch 1-inch
Midrange - 1 x 4-inch
Woofer 1 x 6.5-inch 1 x 5.25-inch

Genelec G Four features a 0.75" Dome Tweeter and 1 x 6.5" Cone Woofer with a Crossover frequency at 3000Hz. On the other hand, the Navis ARB-51 features a 1" Fabric Soft-Dome Tweeter , a 4" Midrange and 1 x 5.25" Aluminum Woofer .

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 Four 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 Four's and ELAC Navis ARB-51's external dimensions.
