In this review, we will be comparing Navis ARF-51 and RP-8000F, two Floor-standing speakers from ELAC and Klipsch. 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 Klipsch RP-8000F 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 Klipsch RP-8000F first before getting into our more
detailed comparison.

Drivers
One of the fundamental differences between these two speakers is that Navis ARF-51 is a 3-way design whereas the RP-8000F is a 2-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.

Cabinet Type and Port Position
Both Navis ARF-51 and RP-8000F 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.
