Focal 165W RC 2 Way Component Speakers Review
56 Focal 20-millimeter, 6-ohms voice coil that is wound on an aluminum former. Around this motor is a specially designed multi-chamber labyrinth that angles back waves away from the underside of the dome while on the side are two clear Perspex terminal plugs with small gold plated terminals. Starting at the top of the larger driver; the 165mm composite “W” fibre cone is actually a far improved version of the early Poly-K sandwich cone material developed during the eighties and used on the old Utopia speakers. The ‘W’ design is quite a complex one and starts with two fine tissues of woven glass that are lighter and thinner than aramid fibers commonly found in other cones. The molecular bond between these materials is also far superior and the resulting cone design mechanically boasts far superior strength and stiffness against compression force. Between these two layers is a third foam layer and, by varying the thickness of the foam, the internal damping of the moving structure remains very controlled. The relationship between the thickness of the glass tissue layers and the foam core allows engineers to carefully optimize the performance range of the cone structure for certain frequencies depending on the particular application the driver will see. 165W-RC 2-way component speakers AUDITION Reviewer: Marty Price Top class components at a middle class price. Focal point The Beryllium series of components are the pinnacle of Focal’s car audio drivers, demonstrating the epitome of French engineer- than concentrating so much on the material. It was here that the engineers developed the reverse dome design and, because of the shape, you get extreme strength against physical deformation in addition to superior dispersion characteristics. So much so that Focal patented and began designing all its high-end tweeters in this way. The rest as they say is history. The design hasn’t changed in years because, after all, if it isn’t broken then why fix it? So when the time came nearly a decade ago to start on a new flagship range of components, Focal retained the diaphragm shape but began looking for a superior material to the titanium and silk it had been utilising. Hence the Beryllium concept was born – here was a material that was stronger than most other elements and at the same time much lighter. Beryllium only has two real downsides; the first is that’s its extremely rare and hard to refine and the second is that it’s quite toxic to humans. It has a density 2.5 times lower than Titanium while its rigidity is roughly triple. Sure it’s more expensive too but in using a Beryllium dome Focal achieves rigidity around seven times that of titanium despite it having the same mass. The surround holding this inverted dome in place is made from a material named Poron and the simplest way to describe it would be as synthetic rubber which is extremely strong but ultra-flexible at the same time. Turning the tweeter over reveals a robust machined zinc alloy frame which was chosen for its magnetic properties. Living within this frame is the tweeter’s powerful motor which is comprised of a neodymium magnet assembly surrounding a double layer, Moving away from the cone the speaker has a butyl rubber surround and a soft material dust cap that has the Focal logo embossed on it in the centre. The entire magnetically-inert Zamak frame is constructed from aluminium and is powder coated grey while the machined The Dynaudio Esotec System 242 is a price point lower at $1149 and has been around for some time If you want to jump into hyperspace, the Audison Thesis 2-ways are at the far reaches of the Universe at $4947 and actually compete with Focal’s Utopia range actually sitting between real bass drums. Even when playing actual extended notes, from the lower tuned acoustic and electric instruments such as tuba, viola, oboe, bass guitar and so on through to the higher range flute, violin, trumpet, guitar and so on, this component set adds a lifelike sound I’ve not heard in years from a component set. Another thing, also quite unusual with component sets, is the crossover’s performance in the transitions from the lows to the highs is almost flawless. Most crossovers need a partial or complete reworking to achieve a seamless blend between driver roll-offs once the car’s interior is factored in. Listening to the highs you again appreciate why these tweeters have amassed such adoration. They’re clinically accurate and crystal clear to the point where you’ll hear details never before noticed. But there is something else about their output that makes them so special. It’s that their sound is as close to the real instrument as you’ll get a speaker producing – to the point by which you may need to be a musician, or be intimately familiar with musical instruments, to truly gain an appreciation of just how impressive they sound. 57 Conclusion Okay so the Utopia component sets might be a little beyond Mr and Mrs Joe Citizen fiscally speaking. However the 165W-RC component set has been designed with this in mind and, thanks to the price tag being significantly less, Focal has now given the aforementioned Citizen family a chance to buy into this prestigious class of what can only be described as speaker royalty.

Removing the components individually allows you to again appreciate the unprecedented build quality. Sadly you don’t get an alloy rifle case with these components but what you do get are two 165mm midrange drivers and two crossovers which are large but still a far cry from the titanic ‘crossblock’ included with the Kit-6 component set. Last but not least are the tweeters that give the component set its title. Also contained within is plenty of mounting hardware and fasteners which are silver plated to complete the overall design look. Seeing as the entire range derives its name from the tweeter material, let us start by examining what makes this smaller driver so unique. Both the Beryllium material and the inverted dome diaphragm shape are trademarks of Focal and are the result of decades of experimentation and development. The biggest enemy of any moving diaphragm is physical distortion, so for years companies have invested big dollars in looking for more and more exotic materials which offer strength and light weight. Despite their diminutive size this rings especially true for tweeters because they have to change direction literally tens of thousands of times a second and retain their shape with near perfection. Starting out in the early years researching various fibre and elemental materials for the tweeter designs, Focal soon turned its attention to the actual shape of the dome rather SIGNIFICANTOTHERS Let us start by posing a hypothetical dilemma most companies would die for. In your 2011 stable you have arguably the world’s best component speakers and subwoofers, as evidenced by the enormous number of accolades Focal’s Utopia drivers have accumulated over the years. However faced with the challenge of producing something new for 2012, where do you go from here? You don’t achieve the tentative title of ‘best speakers in the world’ without investing a heap of coin and, to this end, some of the Utopia range (such as the Grande drivers); are well into six figure territory. So making them superior (and ultimately more expensive) would achieve boasting rights but wouldn’t elevate the company’s sales figures a significant amount. Ever the innovator, Focal instead decided to go the other way; taking the technologies and materials utilised in the acclaimed Beryllium range and injecting them into a new range of speakers designed to sit a level beneath the flagship model. The issue though was typical of Focal; the further it ventured off into designing the new range, the more of the Beryllium technology was employed at no extra expense to you – to the point where if it wasn’t for the magnet and crossover looking completely different, you’d swear the new 165W-RC components were in fact the full tilt Utopia Kit-6 component set. surfaces are all brightly polished. Keeping the motor concentric below the cone is a raised progressive spider and hanging below this is the key component that sets this midrange aside from the flagship midrange. Here it features a larger strontium magnet rather than the neodymium one. Around the frame, just above the magnet, are the air expulsion vents and these coupled with the 8mm intake pole vent allow the motor a continuous power handling of 80 watts. The suspension is stiff enough to handle peak bursts of 160 watts before you run the risk of bottoming the Kapton 32mm former containing the 2-ohms copper voice coil on the machined back plate. The terminal plate is also located on the side of the frame next to these vents. The largest component of the 165W-RC set of course are the crossovers and although these come housed in a beautifully-finished Perspex case, sadly they’re not a patch on the cross-block. They run an open wall design with four posts holding a smoked black Perspex cover featuring the Focal logo on top. Removing the cover for inspection I found that despite the crossovers being from the lesser component set, the high quality standard is still retained. From the two large air-core coils and capacitors that form the 12dB/octave switchable 2.5kHz/3.5kHz filters through to the two massive resistors which form part of the 0dB/-3dB tweeter attenuation circuitry, the components are all top-notch although now they all just have Focal printed on them as opposed to their actual brand names. Installation of the 165W-RC might not be so straightforward in your target car because of the midrange’s large physical size. Because of the strontium employment the midrange’s magnet diameter overall is larger although the mounting depth still remains at 72mm. However, when it came to installation and setting these up in the test car, it ended up being a reasonably easy fit as we use the Kit-7 as our reference. It was just a case of swapping drivers. This also meant that there was a set of A-pillars ready to hold the 165WRC tweeters too. So after bolting both the midranges and tweeters in place we headed out for a day of listening. Given their strong pedigree we did have extremely high expectations and they didn’t disappoint provided you do a little experimenting with the settings in order to optimise the sound. Once you do have them finally setup though, sit back and you’ll immediately start to appreciate why the Utopia sound has become famous worldwide. The midbass drivers are very strong and extremely accurate in their articulation and, thanks to the combination of smart suspension design and the sandwich fibre cone, they resist physical deformation extremely well. This is especially important during the ultra-high speed reciprocating tones such as those associated with the blast beats of someone like Gene Hoglan or Raymond Herrera. Indeed they kick with such force and accuracy that you’ll believe you’re O I N I Z N O E L B NOW AVAIL A c a M / C P & id o r for iPad, And TOUCH US PINCH US WE’VE ALL GONE DIGITAL SOUND+IMAGE AUSTRALIAN HI-FI GEARE CAMERA PRO PHOTO AUSTRALIAN INCAR ENTERTAINMENT Find the special three-issue ZINIO SUBSCRIPTION RATES at AVHub.com.au and www.zinio.com/InCar
