Debuting its UIA-2 Platinum loudspeaker system at the 2018 California Audio Present, Unisinger is registered in California whereas its audio system are engineered and made in Dalian, a port metropolis in northeastern China. Dr. Rong Zhang, Unisinger CEO in command of operations and course of the company, is a Stanford Ph.D. in Chemical Physics (1990), and a postdoc afterwards.
The engineering division for product design, prototype constructing and product manufacturing is headed by Mr. Liu Wei. Advertising inside China is led by a 3rd individual, Mr. Liu Ge. Unisinger employs a total of around twenty staff.
The corporate presently gives 4 models, the UIA-2/Silver, UIA-2/Gold, UIA-2/Gold Plus and UIA-2/Platinum, the last being the subject of this assessment. The cupboards of all four models are produced from aluminum alloy in a cylindrical shape, that includes a principal cavity with a central ‘waist’ the diameter of which is narrower than the higher and lower physique. The airflow created inside the cavity is such that the speed at the waist is considerably higher than that within the prime and bottom ends, thereby forming the “Venturi” effect within the cavity: “When the top (or bottom) speaker unit vibrates to produce a reciprocating airflow, the airflow from the large diameter end moving toward the smaller diameter end will produce an airflow compression effect at the smaller end. When the airflow moves from the smaller end toward the large end, the airflow accelerates the diffusion effect at the exit point, so that the standing wave in the cavity can be effectively eliminated, while the low frequency dynamic response can be significantly enhanced.”
Unisinger claims such physics reduces standing waves contained in the speaker whereas enhancing low frequency aerodynamic response. The truth that the primary cavity is manufactured from aluminum alloy goes to point out the corporate’s willpower and availability of assets in pursuing strong and reliable results with the design idea.
Virtually 4 ft tall, the UIA-2/Platinum is a three-way design. The highest driver is a Seas one-inch front-firing metallic dome tweeter with silk weave, aka material surround. Its design and improvement parameters embrace a remarkably low-frequency cutoff point at an extended 1.5-2kHz, in order to attach with the midrange smoothly. Tonal design parameters embrace “‘bright[er], delicate, warm’ and capable of ‘high resolution.’”
Unisinger turned to Scan Converse for the important midrange software and adopted the 7-inch Revelator 18M/4631T00. Well-known for its sliced paper cone know-how, the slices of the unit “are filled with damping glue which dramatically reduces break-up modes in the diaphragm. In comparison with ScanSpeak’s low-loss linear suspension and the patented Symmetrical Drive (SD-1), it represents a breakthrough in midrange clarity and overall smooth frequency response characteristics.”
The tweeter mount rises out of a tube by way of the back, thus perching out from the mouth of a distinctly reverse horn. Beneath it and firing upward is the seven-inch sliced paper cone midrange. Downward firing is the ten-inch aluminum cone subwoofer.
The Platinum’s downward firing subwoofer is an aluminum Seas D1001-04L26ROY, ported within the rear for elevated airflow and therefore, output, and a true quarter-pounder. As a result of it weighs 22 kilos, includes a 2.2-inch maximum tour and possesses 1.2 T of magnetic flux density, the woofer has a shifting mass of 1 / 4 of a pound. It leads the pack in cone rigidity, efficiency, energy handling and mass minimization for the bottom distortions in bottom-end power.
Another loudspeaker system of fame that also uses all-aluminum cone woofers is the Bowers & Wilkins Nautilus.
In 2016, the corporate set out to release a DIY speaker package by the top of the yr, nevertheless it received forward of schedule and constructed the primary prototype inside three months. The end result was “a square column with mid/low unit face up and the tweeter in another box face front.” The performance was such that the company proceeded to make a mould by casting an alloy cavity for the speaker. This time, the second version was developed after eight months and featured the primary Venturi tube design; the base was square-shaped where the 2-way crossover board was put in. Within the third and last model seven months later, the underside of the Venturi tube was enlarged right into a skirt form the place a 10-inch woofer with a downward firing unit was put in to type a Three-way design.
In complete, it took Unisinger nineteen months to go from prototype to production.
In concept, a speaker that’s constructed of an ultra stiff materials has the benefit of being less sympathetic to resonance, and it doesn’t harm that this constructed cylinder has no corners, shops no power, is totally full-range and weighs solely 77 lbs. So what if it resembles a nuclear power plant?
Unisinger calls the design the “non-baffle.” Quoting Dr. Zhang: “The idea is to eliminate the baffle to form a ‘point sound source’, especially for the high-frequency tweeter unit. This design really brings us the deep and wide soundstage effect, as well as well defined instrument/vocal position for the sound reproduction, reflecting the positions of the instruments/vocal sounds for the recording. In addition, the point sound source also improves the phase relationship between the left and right speakers, so that our speaker system can reflect the phase information in the recording, giving a vivid and realistic sound field. One of the most distinguishing aspects of our speaker is that the normal sound reproduction is out of the box (脱箱-ridding the box). This becomes significant if one uses the system to play a movie soundtrack. Even just using the two main speakers, it can actually form a quasi-surround sound in the room very similar to what one experiences in the movie theater. In contrast, a speaker with a baffle would normally destroy the phase information in the recording so that to render the sound as coming out from the speaker.”
Notably noteworthy is the tweeter’s lack of baffle, rendering it a ‘quasi-point sound-source.’ Dr. Zhang explains the quasi-point sound-source know-how within the following:
“The ideal stereo sound reproduction source, especially for the higher frequencies, should be a point, so-called a point sound source. However, in real life, the speaker unit is an area, not really a single point. Therefore, this smaller sized speaker unit forms a quasi-sound point. Most of the speaker design has a face board, where multiple speaker units are mounted on the board. The sound, therefore, comes out from the board, not from the individual speaker units (due to sound diffraction effects). In our design, we choose to design the speaker with no face board, to make the sound source as small as possible. Because our design eliminates the diffraction effects compared to most other speaker designs, the sound wave phase information in the recording can be preserved and reproduced. The phase information makes an improved sound stage. Hence, this design produces a close to real life sound stage (depending on the sound recording quality too), the sound comes out from a space, instead of from the speaker itself, so-called ‘out of speaker box.’ The result of this quasi-point sound source is the better definition of the instrument positions, which makes the sound stage more real and lifelike. This feature was one of the main inventions in our patent.”
Set at the higher crossover level of 2.1kHz and 150Hz for the lower point, both of 2nd order slopes with 12dB attenuation per octave, the midrange is completely off-axis to the listening place, its dispersion in a upward firing sample. Very important cues of the music are recreated by the tweeter from 2.1kHz and up, however the midrange can also be dealing with a really audible portion of the spectrum albeit firing upward. The company describes the consequences of the midrange as “exhibiting a deep sound field and vivid life-like music.”
The crossover community makes use of an inductor of oxygen-free pure copper enameled wire 1mm thick, and a resistor that’s product of non-inductive cement. A Bennic capacitor can also be used. Solder with 4% silver aspect is used in the welding of the elements and the terminals.
In my system, pushed into 4 ohms by the $29,000, 400 watt-per-channel Bricasti Design Basic Series M28 solid-state monoblock amplifiers, managed immediately by the corporate’s M1 dual-mono DAC, alternating with the $38,000 Move Laboratories Xs Phono and $42,000 XA200.8 Class A monoblocks, and by way of Audio Reference Know-how Analyst SE balanced interconnects, speaker cables and bi-wiring jumper cables, the tweeter and midrange pressurized the massive listening room potently. Positioned roughly eleven ft apart and five ft from the entrance wall, the Unisingers have been 13 ft from the listening position, and instrument recreation was lifelike in scale and really exacting in localization. They didn’t exhibit compression even at high volumes in the giant area, which was an invite to consumer indulgence, a most flattering facet in any product category.
In recreating the “Voice of Spring,” a waltz piece with lyrics performed by soprano diva Kathleen Battle and the Vienna Philharmonic (carried out by the late Herbert von Karajan in 1987 on Deutsche Grammophon), the Unisinger differentiated the contrasting dynamics between the vocal soloist and the orchestra superbly. The diploma of differentiation was comparable to to anchor the diva’s voice distinctly towards the backdrop of the huge ensemble, a feat all the more beautiful from the Seas metallic dome tweeter.
The Unisinger tweeter also pushed air like nothing its measurement I had experienced, its degree of tonal clarity and textural sophistication breathtaking. Although diminutive in measurement, the tweeter stored its composure inside the volume of area its sound wave needed to travel earlier than reaching my ears, never dropping integrity and sweetness.
At close range listening at average quantity, the tweeter could possibly be enjoyed dealing with the listener instantly, for that’s the optimum approach of experiencing the magic. In my giant room, I performed the Unisinger loud; toeing them out from direct firing slightly averted me of bearing the brunt of the highly effective tweeters at excessive volumes but without dropping their magic. The tweeter tube resembles a reverse horn, pressurizing the backward firing wave exponentially from the back of the diaphragm and down, in a chic execution of again wave elimination.
The downward firing woofer misplaced a considerable diploma of definition and pressure when the speaker was on carpet. However when placed on the cement flooring overlaid with wooden tiles, the Unisinger shook the home while Tidal-streaming the Clint Mansell soundtrack Moon. It didn’t require an extra subwoofer. Its cylindrical, nuclear energy plant-like structure of a cabinet helped delivered the cleanest and best-conforming bottom-end I’ve heard in reminiscence.
The rendition of the church pipe organ within the LIM K2 HD CD, Cantate Domino, remastered from the unique Proprius recording, the Unisinger as pushed by the Bricasti Design system lured me into growing the quantity just to prove to me how indestructible it was. The Cross Labs system did induce the efficiency of the yr from the Unisinger towers, pressurizing the listening area with its high-bias, Class A musicality and power, however the Bricasti Design monoblocks at 70% of the cost of its Cross Labs counterparts persuaded the Unisinger to offer a unique perspective, one less expansive however equally indulging.
Down firing a woofer has been carried out by corporations earlier than Unisinger, all iterations seemingly striving to impress by way of forceful shows, however the Unisinger was delicate and gradual when referred to as for. The out there degree of energy delivery was epic, from the subtly beneath driving to the rambunctiously overpowering, and not in-the-chest as many similarly priced bins would effectuate. Having experienced what will be the most articulate downward firing woofer by advantage of the cylinder body, I threw all types of recordings with bass material at it and the speakers stored obliging effortlessly. A standalone Unisinger subwoofer system can be a formidable entry into the marketplace.
And I’ve been neglecting the upward firing midrange all this time. The tweeter flew at my face whereas the midrange was tucked away on the prime of the cylinder, but sonically they each have been disappearing act champions. The midrange accorded atmospheric cues concerning the music that added realism to the sound of devices. There’s something to be stated for the expertise of a midrange that traverses the essential vary of 150 to 2,100Hz and radiates in an omni-directional 360 diploma sample, and not straight at you. Judging from a sea of spatial and tonal cues I heard, the arrangement appeared to be working simply high quality.
Genuinely, the mixing of the drivers was such that it was impressively conducive toward piano music listening. The Unisinger’s portrayal of the slowing getting old Murray Perahia’s Chopin 24 Etudes was first-class in dynamic contrast and tonal integrity. The copy of harmonics was ethereal and surreal. This degree of integration makes listening to solo classical piano fun, because their method of reproducing music was complete and utterly spectacular.
It’s not unconventionally lengthy in improvement historical past for a speaker to be created in nineteen months, and now in hindsight, seeing what Dr. Zhang and his group can do, I wish that they had taken a bit longer to amaze us with something even more extraordinary.
All features of the Unisinger UIA – 2/Platinum extol quality. From the creatively penned handling and advertising messages on the outer delivery field, and the meticulously designed EPE shockproof internal packing, to the 100-lb matte paper Eight-page instruction guide and its thoughtfully written contents, Unisinger impresses me as a well-organized group and the Platinum a world class, intelligently executed undertaking, worthy of an enthusiastic suggestion. I sit up for further future adventures with Unisinger.
