Q1. What are the main differences between the Uni-Fi and the Debut Series?
A1. The Uni-Fi is intended as a step up in performance compared to the Debut series. As such it is both a three way system and incorporates our concentric driver technology, named Uni-Fi. In addition, as a three way, the drivers can be better optimized for their particular frequency range and so the cone materials are chosen for this purpose (aluminum for the bass and midrange drivers, cloth dome for the tweeter).
Q2. What are the main advantages of a concentric driver?
A2. First, what is a concentric driver? In general, it is a driver where the tweeter and bass/midrange driver have been combined into one compound unit. The tweeter is mounted at the apex of the cone, sitting directly on top of the bass driver pole piece, where the dust-cap would normally be found. The result of this is to match the off-axis characteristics of both drivers so that the sound is more even across the frequency range. The imaging will then be better, the sound character will be more consistent throughout the listening area, and will be les influenced by the acoustics of the listening space.
Q3. What are the main advantages of a 3-Way speaker vs. a 2-Way speakers?
A3. The principal advantage is that the drivers are operating over a narrower frequency range. As a result they can be better optimized for their intended purpose. In particular, the bass/midrange driver is no longer required to reproduce both bass ad mid frequencies simultaneously. This reduces the total amount of power going into each driver, reduces distortion and produces a clearer midrange and more dynamic bass performance.
Q4. What are the advantages of the aluminum drivers compared to other materials?
A4. The best choice of cone materials is governed by the intended application. Not all materials are ideal for all applications. The advantage of aluminum for the bass driver is its good balance between performance and cost. It is easily formed, consistent in production and has a good ratio of stiffness to weight. More exotic materials have very little further advantage in this size of bass driver. With the midrange driver, we generally find ourselves working with materials that are not rigid over their operating range. For example in the Debut speaker range, we use Aramid fiber. This gives us the capability of carefully controlling the cone flexing to get the best performance. This difficulty in design is somewhat ameliorated by having a three way speaker, and also now allows us to change to an approach that eliminates flexing within the operating range. Aluminum, as optimized in the Uni-Fi midrange, has its first flexure mode at a high 8kHz which results in excellent performance.
Q5. Is the soft dome tweeter in the Uni-Fi series the same as the Debut series?
A5. Although developed from the Debut series tweeter, it has been further refined. It now has a neodymium magnet, and has been modified to work best when mounted within he midrange driver as a concentric system. Additionally the fixed grille over the dome has been carefully designed to help extend the frequency range beyond 25kHz.
Q6. The specifications shows the Uni-Fi tweeter goes out to 25kHz? What is the advantage of this?
A6. Generally the frequency range specified indicated the limits of where he performance has started to diminish. Many dome tweeters that are specified to extend out to 20kHz are already up to 3dB down at that point. By engineering the tweeter to extend to over 25kHz, we make sure that it has not already rolled off by 20kHz.

I briefly spoke to staff from Elac at the 2016 Newport audio fest about the possible availability of Uni-Fi towers in wood vs the current vinyl covering. They said that Europe now has that option and there is consideration of the U.S. having that option as well. when will the U.S. market be informed of this possible availability?

I own a pair of ELAC Debut B6’s my amp is the Marantz PM6005 have been totally satisfied by the Elac. I was looking at moving up to the ELAC Uni‑Fi UB5. My question is will the Marantz amp do justice to the UB5’s they are rated at 60 watts @ 4 ohm. Also do you intend to make a UB6 anytime soon?

I’m glad you like the Debut B6. I run the UB5 with an amplifier that has similar if not worse specification than your Marantz amplifier all the time. If you like the Debut B6 you will likely be jumping for joy with the UB5. Unfortunately, the UB6 is not on the agenda.
