Berlin Series – The Harmony Of Resplendent Finesse And Brute Force
For the consummate music enthusiast who desires not only superb control but also volume aplenty! The Berlin range offers the ultimate balance between precise aural reproduction and forceful kinetic output. Audiocircle has combined superb quality materials such as aluminium-paper composites with advanced no holds barred design architecture to provide audiophile level parameters in conjunction with serious sound pressure output levels. The Berlin range are the ultimate speakers for those who want the absolute best of both worlds!
Design Ideologies
The second generation of Berlin components are evolved from the highly acclaimed original series, with the latest variant incorporating far superior technologies and materials in comparison with those previous. Utilising elements like blackened aluminium paper composite diaphragms, large heavy duty exceptionally vented voice coils, aluminium die-cast baskets, extremely strong magnets, fully machined components and high quality plated connection terminals; these components are unlike anything previously heard within this price point. Let’s take a more in-depth look at what makes these components so special.
Elementary Kinetic Force – The Midranges
Starting with larger BL-W6 driver; the deceptively plain 166mm driver is not quite as elementary as first appearances suggest. Its cone starts with a fine woven paper pulp base chosen in order to output a delectably smooth sound. Reinforcing this and providing exceptional damping characteristics is a blackened aluminium layer. It’s been molecularly bonded with the lower diaphragm and provides an exceptional Young’s Modulus without saddling it with excessive weight. This allows the aggregate cone to maintain its structural integrity even under the most challenging of kinetic demands. The centre of the cone is home to a carefully shaped dust cap which not only combats resonance but also serves to push the speaker’s output azimuth well forward of the piston face. Not to be outshined by the exotic cone, the top suspension features a specifically profiled butyl rubber ‘dual-M’ surround. These twin parabolic curves flex and move varying distances depending on the drives linear movement, thus ensuring everything is kept within the strictest of alignments. Assisting this and forming the lower portion of the suspension is a non-progressive polycotton spider, which along with the flux oversees carefully the linear movement of the motor within and provides a sensitivity of 90dB. Unsurprisingly it’s not just any old motor either; far from it. Audiocircle worked meticulously on the motor itself the result being a 32mm Kapton former wrapped with a four ohm copper voice coil, tuned by dual copper shorting rings. The first of these is embedded within the pole piece whilst the second has been placed within the confines of the magnet. Space and public interest won’t permit me to delve too deeply into the intricacies of this system, suffice to say that these rings work to rectify the various issues posed by closed loops of electrical currents within the conductor, sometimes known as Eddy or Foucault currents. In layman’s terms these rings alter the magnetic field via Faraday’s law of induction, the result being a lower inductance and far less overall distortion. Turning the unit over reveals a magnetically inert die-cast aluminum frame complete with four pairs of aerodynamically transparent webs which serve to hold the ferrite magnet firmly in place. Peppered liberally around the perimeter are numerous intake vents which allow for titanic gusts of cool air to be inhaled with each reciprocal movement. From there said zephyr travels over the voice coil and former before being expelled via a 10mm pole vent, bell mouthed to ensure that no fluid dynamics issues rear their ugly head. This cooling system is most efficient and allowing the motor a continuous power handling of 120 watts. Likewise the suspension, despite having a very low fluid resonant frequency; is robust enough to handle the odd peak burst of double that. The motor also enjoys a high Q, making it ideal for automotive locales such as doors. Palladium plated terminals are located upon one side between the web fingers and these adjoin silver-coated conductors leading to the coil within.
Crystal Clear Highs – The Tweeters
Audiocircle has cut no corners pertaining to the design of the BL-T26 tweeters either, utilising ideologies from numerous high end design concepts to achieve its goal. Featuring a 26mm diaphragm constructed from a base of silk that’s been coated with a clandestine chemical coating; the dome profile is optimally designed to provide superb off-axis response. Even the grille protecting this hasn’t escaped Audiocircle’s attention, being designed with hexagonal perforations in order to remain as transparent as possible. Living beneath the dome is a motor featuring a similar copper shorting ring to the midrange which works on conjunction with the four ohm voice coil wrapped tightly upon a thermally efficient 20mm aluminium former. Enshrouding this is a fastidiously designed neodymium magnet whose physical shape and position are such that it’s able to impress a substantial influence over the voice coil. The die-cast aluminium rear housing holding all this is no less the marvel. Back waves emanating from the diaphragm and their inherent turbulence create serious issues for a tweeter attempting to reciprocate many thousands of times per second without distortion. Each reciprocal movement sees this cavitation create a choppy mess of compression and rarefaction waves that the proceeding cycle must withstand and overcome. In order to allay this Audiocircle designed an elaborate labyrinth within the backend, creating an almost aperiodic like chamber and lining it with a specially design synthetic material. This functions as the ultimate labyrinth chamber trapping the back waves and keeping them away from the underside of the dome ensuring their kinetic energy is hastily diminished. Likewise the cooling system is also a tad departed from the norm with Audiocircle electing to omit the standard ferro-fluid cooling methodology and instead run with an advanced fully ventilated multiple pole air cooling system that allows for a continuous power handling of 120 watts. This aspect along with the suspension is conducive to an exceptionally unrestricted movement leading to more natural sound, deeper resonant frequency and lower F3 point. These enable to the driver to blend seamlessly with its bigger sibling.
The Frequency Distributor – The Crossovers
Speaking of seamlessly conjoining driver output; this is the domain of the crossovers. Beautifully hand crafted they come housed in robust ABS cases finished with smoked black vented Perspex covers. Beneath the cover reveals an interior that’s full of high quality goodies, such as MOX resisters and Mundorf capacitors, the latter working in conjunction with the low resistance air-core coils providing second order 12dB slopes centred on 2200Hz. Unlike many mid-range crossovers these units also feature phase correction. Sometimes referred to as an impedance linearization circuit; these help to align the drivers electrically by altering the phase at certain points in order to see the sound from both arrives at you simultaneously. Testament to Audiocircle knowing a thing or two about crossover design there’s also a quintuple point switching system allowing you to tune the tweeter attenuation perfectly to suit your application. Defense wise if you’re one guilty of getting a little over zealous with the volume at times, rest assured Audiocircle has incorporated twin protective circuits in the form of a PTC fuse in addition to a halogen bulb which will actually light up if you’re starting to encroach upon the circuit.
It’s All In The Listening – The Auditioning Process
Not only have we installed many of these components here at Fhrx Studios, we’ve also conducted extensive testing of them. Installing the full component set is quite straightforward thanks to the modest mounting depth of 65mm and 20mm respectively; dimensions that’ll see them go happily into most modern cars. With components mounted and running in nicely via correlated pink noise, we rummaged through the good old music collection accumulating all sort of titles. We were super keen to get into these drivers given our extensive experience with Audiocircle equipment hitherto. Within audio circles Audiocircle has quite the reputation for sounding awesome straight out of the box with very little ado; the Berlin’s extend this trend and then some. In reality when talking high-end speakers you don’t get bad ones so to speak, nevertheless some do consume entire days before they sound good. Not these bad boys though. Right from the get-go they’re quite something to behold. The midranges are very stout in their aural reproduction, punching not only with impressive accuracy but with real definition right down into the lower midbass regions, validating that combination of cone material and suspension design. The higher orders of sound are likewise remarkably precise. Whether you’re playing the normally shrill sound of violins, through to the crash of symbols; the tweeters remain clinical, smooth and crystal clear to the point where they tend to sound more akin to the real instrument than that of a mechanical diaphragm. The crossover is equally impressive, guaranteeing the drivers transition seamlessly in order to provide a harmoniously clean reproduction across the entire audible portion of their specified 39Hz – 30kHz frequency range. The overall linearity of the sound is simply beyond reproach.
Coming into land; rocking up to your local audio competition proudly proclaiming your car is full of Audiocircle might garner you the puzzled look from those folk caught a little unawares. Trust us though when we say you’ll have the last laugh. For one doesn’t just happily return to audio mediocrity once they’ve auditioned speakers of this ilk. Audiocircle has long had a reputation for upstaging its competition, and the Berlin components highlight perfectly why this reputation is so well deserved.
