FLAT-C60 Flat speaker driver unit one pair
High resolution sound quality, three-dimensional localization
The ideals asked for audio speakers are lobby
· In order to emit evenly all frequency bands from the entire area of the diaphragm to be ejected evenly without delay, the "Nippon" due to the time difference of the sound is eliminated, and more faithful reproduction is possible.
• The requirements for ideal diaphragms (diaphragms) should be strong and lightweight, and even more air. Development of special foams to clear these conditions.
· A natural honeycomb structure in which foaming is made uniform throughout the diaphragm area with a thickness of 4 mm. Humidity is strongly suppressed as much as possible due to aging due to aging.
-In the larger internal loss of the diaphragm (the amount of air is large), the material sound unique to the diaphragm material is operated while canceling with the internal air while canceling the internal air, so it has realized a clear noise that has no choice.
• The voic coil molded into the square shape is the inner and outer double rolling, and the magnetic circuit is incorporated only on the long side of the coil. For this reason, an inductance that causes turbidity of sound is less likely to occur, and flattening of the impedance and frequency characteristics of the impedance across the entire band can be achieved simultaneously.
· The magnet adopts neodymium N50m and constructs a powerful magnetic circuit. Waste voice coil motion is minimized and high transient characteristics without phase slippage.
· The edge is durable and adopted artificial leather with excellent durability and is double edge to sandwich the outer periphery of the diaphragm from the front and back. As a result, the screw phenomenon of the diaphragm is minimized, and the piston movement becomes smooth.
• A full range design that does not adopt the network (contributing to audio signals) is faithfully reproduced by the full range design that is sent from the amplifier.
· Although the radiation angle of the sound is about 60 ° in the general speaker, the FAL flat driver is 120 ° or more. Therefore, the sound field expression is wider, and the stereo area is also vast.
· The cone type speaker is difficult for the smaller the size, the less sizes to play the bass with only the outer peripheral part. FAL Flat Screwdriver allows you to play a small size or sufficient bass for playback using the entire diaphragm. (Compared to 38-40 cm woofer)
· In general, when the output from the amplifier is smaller, the power from the amplifier is reduced, and the power to move the speaker is smaller, and the high noise and the bass are difficult to output. On the other hand, the flat driver does not collapse the bandwidth balance even at the time of small noise due to the powerful magnetic circuit because the diaphragm is small and light.
• A 2.5W amplifier will be practical for the high efficiency of 94 dB.
Flat C60 diaphragm and yoke improvementThe point of improvement is that by inserting a reinforcement in the middle part of the voice coil bobbin, eliminating the resonance of the middle and high regions and the improvement of the oil tolerance has been achieved.
By placing the aluminum pipe reinforcement in the voic coil bobbin intermediate portion, the resonance is reduced by reducing the resonance due to the strength of the horizontal direction due to the electromagnetic force, and the vivree sound at the time of high input and specific sound source reproduction was eliminated. Technology is applied to C60.
FLAT C60 Conventional Frequency Characteristics
FLAT C60 Improved Frequency Characteristics
One Point AdviceIt is ideal for the shape of the Finnish Birch and Russian Birch to the enclosure material and the Russian Birch, and the shape that does not make a parallelism for standing waves. As it is, please use as a full range. Crossover is 10 kHz or more with a.m.t air motion tweeter, and C60 should drive with natural attenuation without high cut.
|Frequency characteristic||40 Hz-14kHz|
|efficiency||94 dB (1 m)|
|size||148 (H) x 128 (W) × 55 (D) mm|
