In this review, we will be comparing Navis ARF-51 and BW 603, two Floor-standing speakers from ELAC and Bowers Wilkins. The main difference between these two speakers is that the ELAC Navis ARF-51 is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the B&W 603 is a Passive speaker so has to be matched with an amplifier to get any sound from it.
Let's have a brief look at the main features
of ELAC Navis ARF-51 and B&W 603 first before getting into our more
detailed comparison.

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 Navis ARF-51 and BW 603 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 ELAC Navis ARF-51's and B&W 603's external dimensions. ELAC Navis ARF-51 has external dimensions of 1070.0 x 247.0 x 294.0mm ( 42.125 x 9.6875 x 11.5625inch) whereas B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) .
B&W 603 is 57mm narrower and 85mm shorter than ELAC Navis ARF-51 but it is also 46mm deeper.
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 ELAC Navis ARF-51 is approximately 726.2cm2 / 112.6inch2 and base area of the B&W 603 is approximately 646.0cm2 / 100.1inch2. The Navis ARF-51 requires 12% more surface area than the BW 603 which gives it a small disadvantage on placement in tight spaces.
