Eighteensound 8" Treiber

Eighteensound 8CX401F 8 Ohm
The 8CX401F coaxial transducer is a 8 inch - 1 inch coaxial driver combining excellent linearity with good efficiency and power handling capabilities. It is primarily intended for compact reflex enclosures and, because of its versatile characteristics, may also be used in multiway systems or ceiling applications. Its nominal dispersion is 90 degrees. The curvilinear, paper LF section cone is formed using a unique wood pulp composition designed to achieve the best possible rigidity and stiffness. A polycotton multiroll surround to provide increased excursion whilst controlling break up modes carries it. The 51mm Ø state-of-the-art, aluminum wire voice coil employees same technology of that fitted to our top-of-the-range models using our Interleaved Sandwich Voice coil (ISV) technology. In essence, a high strength Fiberglas former is used to carry windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly, which, in conjunction with the highly advanced design of the magnetic structure, provides a high force factor or BL. The high frequency driver incorporates a polyester material diaphragm for best movement and stress control; the special radialribs increase stiffness avoiding uncontrolled vibration modes in the usable frequency range. An edge-wound copper clad aluminum voice coil wounded on treated Nomex completes the diaphragm assembly. A computer aided FEA has been used in order to maximize the cone profile coupling and to control the energy in the desired frequency range. A dedicated high quality passive crossover network is available upon request. With the increasing use of outdoor audio events, the ability to perform in humid environments is another feature of the 8CX400F. This is achieved by means of exclusively developed humidity repellent cone treatment.DATENBLATT

Eighteensound 8CX650 8 Ohm
The 8CX650 is a 8" - 1" coaxial transducer designed for use in compact reflex enclosures and stage monitors as small as 30 lt, with a nominal dispersion of 90 degrees. The high force ceramic single magnet structure makes the 8CX650 a lightweight speaker for its performance class - only 5,5 kg (12 lb). The 65 mm (2.5 in) LF edgewound CCAW voice coil employs our Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglass former carries windings on both the outer and inner surfaces to achieve a balanced coil with a uniform distribution of mass and motion energy. This results in an extremely linear motor assembly. The low-profile smooth straight LF cone provides a smooth response within its intended frequency range and maximum reliability under high mechanical stress. Equipped with a proprietary hybrid radial tangerine phase plug, the integrated HF compression driver has been designed to deliver a smooth coherent wavefront at the horn entrance in all working frequency ranges with a high level of manufacturing consistency. The phase plug, with its short openings and high flare rate value, assures low distortion and remarkable improvements in mid-high frequency reproduction. A copper sleeve reduces inductance value above 10kHz, improving phase and impedance linearization. The HF diaphragm assembly is made by proprietary treated Polyethylene material. Thanks to its superior diaphragm dimensional stability, Polyethylene shows constant behavior during its whole working life. Moreover, this particular material with its very high value of elasticity modulus is capable of superior transient and intermodulation distortion response. The flat suspension shape is designed to maintain low stiffness and low mid-band distortion and response. An edge-wound aluminum voice coil wound on proprietary treated Nomex completes the diaphragm assembly. Thanks to its physical properties, the proprietary treated Nomex former shows a 30% higher value of tensile elongation at a working operative temperature when compared to Kapton. This feature enables proper energy transfer control from the voice coil to the dome in real working conditions. Moreover, this proprietary former material is suitable for use in damp and wet environments. A specific dedicated HF driver throat design has also been chosen, maximizing the cone’s profile coupling.DATENBLATT

Eighteensound 8M400F 8 Ohm
The 8M400F is a high power, high output, 200 mm (8 in) midrange for high level professional use.The excellent sound quality has been achieved as a result of extensive research on midfrequencies intelligibility. The 8M400F has been designed for use as a midrange in both horn anddirect radiation, closer or reflex enclosures, as small as 3 lt. The curvilinear cone, made with ahigh damping wood pulp, has been designed to achieve the best possible linearity within itsfrequency range. The in-house developed cone treatment is a humidity repellent and alsodampens the bell mode resonance significantly. The 51 mm (2 in) ISV aluminum voice coilassembly is wound on a strong fiberglas former to improve force transmission and powerhandling. ISV technology is based on a high strength fiberglas former with half the coil wound onthe outside and half on the inside and bonded together using unique high temperature resinadhesives. The powerful magnet assembly assures high flux concentration. The force factor andpower handling are at an optimum level. The direct contact between the finned basket and themagnetic structure significantly improves thermal connection and heat dissipation, furtherincreasing power handling and lowering power compression. The copper shorting ring on thepole piece reduces inductance and improves transient response and phase control in the midfrequencies.DATENBLATT

Eighteensound 8MB400 8 Ohm
The 8MB400 mid-bass transducer has been developed in response to a specific market requirement for a 200 mm (8 in) midbass driver which combines excellent linearity with good efficiency and power handling capabilities. It is primarily intended for use as a midbass driver in compact 2-way reflex enclosures with a 1 inch compression driver or tweeter but as a result of its versatile characteristics, it can also be used in multiway systems. The curvilinear, treated paper cone is formed using a unique wood pulp composition designed to achieve the best possible rigidity and stiffness. This is carried by a polycotton multiroll surround to provide increased excursion whilst controlling break up modes. The 50 mm (2 inch) aluminum wire voice coil employs same Interleaved Sandwich Voice coil (ISV) technology. It is composed of a high strength fiberglas former carrying windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly which, in conjunction with the highly advanced design of the magnetic structure, provides a high force factor or BL. The voice coil is cooled by incorporating airways between the chassis back plate and the magnetic top plate to channel heated air away from the voice coil and gap and dissipate it. In-house FEA CAD facilities have been used to optimise flux density and BL factor within the air gap. Due to the increasing use of sound systems at outdoor events, the 8MB400 ability to perform in humid environments is a key feature. This has been achieved using an exclusive cone treatment which renders the cone resistant to humidity.DATENBLATT
