Secret - Ao Lei Audio PF12+
[Audio Network Information]
Ao Lei PF+ series speaker "family portrait"
Since April of this year, the new PF12+ speakers of Aolei Audio have been put into production one after another. The new PF12+ has some more breakthroughs and changes on the basis of continuing the old models. In order to further enhance the audio-visual effect of the PF12+, O'Reilly has made effective changes in terms of woofer unit changes and crossover changes based on the improvement of the original product unit, and further integrated into its own unique style, the new 12+ The interpretation is more distinctive and attractive.
First, the woofer unit change <br> The biggest change is the change of the horn magnetic circuit system: the purpose of the magnetic circuit system design is not only to meet the structural changes, but also to obtain a larger and stronger magnetic flux density, and Low distortion.
The magnetic circuit system of the new PF12+ bass 12F400GB+ is an external magnetic circuit structure. T iron, Huasi outer diameter is extremely large 10-15mm, thickness increased by 1-2mm, magnetic routing original ∮180mm high-quality ferrite magnetic steel increased to ∮190mm. The new woofer unit has stronger magnetic field strength, wider magnetic field density area, lower distortion, and further reduces distortion and increases flux path. The new woofer optimizes T-iron. Conical magnetic plate section.
Design test parameter indicators also prove these improvements, Qms, Qes, Qts, more moderate, while the amplitude range increases, efficiency increases, sound pressure level increases.
In terms of hearing experience, the new woofer unit is more powerful, dynamic and more powerful, and the bass is fuller.
Main character: PF12+ speaker
Second, the tweeter features enhanced <br> The tweeter has not changed, using MELAY polymer synthetic diaphragm, compared with the traditional titanium film, the sound is brighter, clearer and more transparent. There is no metal rasping sound for general professional speakers. Mainly because the MELAY material is smaller in density, more rigid, moderately damped, and less distorted than the titanium film material.
Third, the frequency divider change <br> Mainly the change of the components of the crossover, the design of the crossover follows our Ole's consistent style: 3Mm fiberboard, hand-stitched welding, so that the sound transmission speed is faster, the distortion is smaller.
The selection of components is also very fever; 1.4mm wire diameter large air core oxygen-free copper inductor, XPP grade metallized polypropylene non-inductive capacitor, high-power non-inductive cement resistor and metal resistor (more easy to dissipate heat).
Fourth, the speaker technology is further optimized <br> A good speaker mostly has good objective indicators, the new PF12+ measured technical indicators are relatively good, through the following new frequency response curve, impedance curve chart, we can more intuitively feel the new Balance and coordination of the PF12+.
Speaker frequency response curve
The corresponding frequency curve of the speaker is one of the most important technical indicators of the speaker. The frequency of the speaker indicates the style of the sound of the speaker, the effective frequency response range and the balance of the frequency response of each segment. The ideal frequency response curve is a horizontal line without undulations. But unfortunately such a curve has not yet been made by humans.
The flatter the frequency response curve, the better the balance of the sound of the sound. When playing back music, the more realistic the performance of the instrument and the human voice, the stronger the sense of presence.
The wider the frequency response range, the stronger the replay capability, and the better the range of parts in the high, middle, and low parts.
The frequency response curve of the new PF12+ is relatively flat, basically maintaining around 97dB±2dB (high-fidelity curve is generally around ±3dB), and the sensitivity is higher than that of the general professional audio, indicating that the speaker has low requirements for the power amplifier, and the smaller power can be promoted. Better voice.
The frequency response curve of the new PF12+ is combined with the sound style of Oleite. The low frequency is dynamic and the vocals are more transparent, clear and bright. From the trend of the frequency response curve, this style can be basically seen.
Impedance curve
From the impedance curve of the new PF12+ speaker, the characteristics of the two peaks are obvious, the symmetry is good, the ratio is moderate, and the frequency of Xie Zhen is about 50 Hz, indicating that the new PF12+ speaker has an ideal open tuning state, and the sense of low frequency is sufficient. Big.
The impedance curve of the new PF12+ speaker, the first resonance peak is around 28 Hz, the impedance is about 43 ohms, the second resonance peak is around 88 Hz, the impedance is about 46 ohms; the middle and high-end maximum impedance is about 34 ohms, the curve is undulating. Not big, the speaker impedance is good, and it has a good match with the amplifier.
Luxury audition room
5. Audiovisual integration into the unique style <br> In the Auree luxury audition room system, I listened to some songs and confirmed the new PF12+ from different angles: such as "Xihai Love Song", "Since you left, you have lost your gentleness since then." Waiting for this snowy mountain road is long, listening to the cold wind and whistling still. At first glance, you can't see the side....". The song is mellow and sweet, long and wide, with a hint of aristocratic atmosphere, just like a beautiful singer standing in your present, affectionate Singing; Listening to "Let's go to love" "You stand alone on the corner of the street, the scars on your face are gone, you smile at me, this picture is like a knife..." The voice is rich in expression, the details are obvious, the voice is sad and sweet; Listening to Zhao Peng's "Song of the Boat", I feel that the bass is full and strong, and there is a kind of low-frequency breath that comes from the face; listening to a foreign big dynamic music, you can clearly feel the abundant energy, all kinds of slight details easily do not perform well. Legacy, the atmosphere is strong, and another foreign language music gives people a sense of dynamic sound, the adjustment of strong and weak music, the transient strong sound, and the sense of energy...
In general, the new PF12+ with Oleite style is incorporated. In the audition, we can clearly feel the vocal transparency, the sound density is strong, the sound is lively, the uniformity of the overall sound, the dynamics of the sound. The ability to portray details and the brightness of sounds all have ideal performances. Based on this, we can believe that the launch of the new PF12+ is undoubtedly a solid step forward in the product development and career development!
