Top full-range speakers 8'' inch really full-range speaker

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Introduction:

This full-range unit was developed in-depth, and its drum and dust cap are maverick, short voice coil magnetic circuit has reached the level of monitor, simplifying the compensation requirements of the late, without any notches, filtering and compensation, it only need a speaker cable. Particularly recommending to match it with a similar 2A3 single-ended hi-end amplifier and high-end transistor low-power amplifier; this products have been exported in bulk around Europe.

1. New development

The new team of designers has nearly 20 years of experience in speaker design, some of them are senior engineers who has ever been serving the Europe and the United States most well-known audio brand design ,some of them have served in the state-owned Institute of Electro-acoustic, and also some of them have been in well-known professional audio companies and a HIFI manufacturers senior engineer . Lasted three years of uninterrupted research and development began, drawing on a number of well-known full-frequency unit.It is a huge investment.

2. Correct bass parameters

Right bass parameters:In the development stage,we selected a new generation of Germany Kilppel analysis and testing system for parameter optimization. It is different from the conventional test system, only using for 1 meter and 1W signal test; Klippel analysis test system when in real-time status (such as: 1W ,, 10W, 50W, etc.) will be close to the actual use of the test. Thiele - small parameter is very close to the ideal value (Thiele-small mainly has 0 value, Vas, Fs; for HIFI unit with specific purposes, this three parameters are in specific range), using a simple inverted phase box you can easily balance the full frequency response.

3. Stable and uniform magnetic field design

Stable and uniform magnetic design: In particular, FEMM magnetic circuit design is selected, finite element analysis is adopted, and other brands are discarded only for pursuing strong magnetic field. We set the target value of Thiele-samll parameters, set uniform and stable magnetic field, in particular, to avoid the use of the unit in the case of voice coil alternating current on the magnetic circuit disturbance.

4. Specialized drum paper

Special drum paper: cross-section of the drum paper is using the overhanging curve , more superior then hyperbolic, parabolic, or straight line . Its material is specially selected, including rattan fiber, mulberry bast fiber and kenaf fiber; which specifically designated Vietnamese rattan fiber as the main raw material, variety, origin and harvest date all have special requirements. Drum paper processing technology is also specified, including the molding process, the ratio of ingredients and different thickness of thin-Li curve. To achieve sound transmission speed, split less vibration, fast transient response, distortion, internal damping and loss of appropriate, small volume density, light weight, high strength, good toughness requirements.

5. Special dust cap

Special dust cap: After a dozen experiments, the final selection decided to choose a new type of transmission of metal alloys,we have discarded the test of various types of paper, iron alloy, aluminum alloy and known as the golden sound film copper alloy rice material. Its appearance is inspired by the eggs, the whole surface is scanned with a laser from a native ostrich eggs, and the frequency response curve is even better than other forms!

6. True bass:

different from the traditional classical full-frequency ± 1mm dynamic range, this eight-inch full-range unit's distortion-free amplitude reaches Xmax = ± 3.2, due to the relatively large effective vibration area of the eight-inch unit, in the conventional case, to achieve the same bass energy, 5-inch unit displacement amplitude must reach ± 10mm, and the displacement of the three-inch unit must reach ± 20mm, that is very giant!
