Eighteensound 6,5" Treiber

The 6M44 is a high power, high output, 6.5" midrange for high level professional use.The excellent sound quality has been achieved as a result of extensive research on mid frequencies intelligibility. The 6M44 has been designed for use as a midrange in both horn and direct radiation, closer or reflex enclosures, as small as 3 lt. The high damping pulp cone, has been designed to achieve the best possible linearity within itsfrequency range. The in-house developed cone treatment is a humidity repellent and also dampens the bell mode resonance significantly. The 44 mm CCAW voice coil assembly is wound on a strong fiberglas former to improve force transmission and power handling. The powerful magnet assembly assures high flux concentration. The force factor and power handling are at an optimum level with improved thermal connection and heat dissipation, further increasing power handling and lowering power compression. The demodulating ring technology reduces inductance and improves transient response and phase control in the mid frequencies.DATENBLATT

The 6ND410 is a very high output, state-of-the-art midrange product for high quality professional use. The high level of sound quality has been achieved thanks to extensive research by Eighteen Sound engineers which focused on implementing mid frequencies intelligibility. The 6ND410 can be used as a midrange in both horn and direct radiation, closed or reflex enclosures, as small as 2 liters. The extremely powerful external neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. Consequently, the levels of force factor and power handling are at a top professional level with an optimum power to weight ratio. A consistent heat transfer is guaranteed by the encapsulation of the magnetic structure in the interior of the basket, offering a large contact space between the back plate and the dissipating structure. The curvilinear cone-surround, has been created using computer aided vibrational modelling software to move all undesired bell modes out of the usable frequency range. The 45 mm edge-wound voice coil assembly and terminals have been designed to minimise the moving mass while reinforcing force transmission. The 3 threaded back plate holes give the final user the opportunity to insert an external customised heat sink, if further heat dissipation is required. A proprietary humidity-block cone treatment makes the transducer suitable for outdoor use in adverse weather conditions. In addition, a special coating applied to both the top and back plates makes the 6ND410 far more resistant to the corrosive effects of salts and oxidization.DATENBLATT

The 6ND430 is a 6 inch neodymium woofer designed for low frequency reproduction in 2-way systems or multiway systems where both low weight and high intelligibility are required. The speaker has been specifically designed for compact reflex enclosures where high quality low-bass and mid frequencies are required such as studio monitoring applications. It is also currently used in line array or multiway systems with excellent results. The extremely powerful external neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. The levels of force factor and power handling are, as a consequence, at a top professional level with an optimum power to weight ratio. A consistent heat transfer is guaranteed by the encapsulation of the magnetic structure in the interior of the basket, offering a large contact space between the back plate and the dissipating structure. Particular effort was given to the surround shape and material design in order to minimise the resonances on mid range frequencies. The new design, realised with specified rubber based material density, offers a consistent dampening to typical bell modes. The 45 mm voice coil is made from a light-weight aluminum wire and assures linearity and high power handling.

The 6NMB420 is a 44mm voice coil 6.5 inch neodymium midbass transducer designed for mid low frequency reproduction in system designs where high intelligibility is required. When compared to our 6ND410 state-of-the-art midrange transducer, 6NMB420 offers a lower frequency resonance and a longer linear Xmax value. As a result the speaker shows an increased output around 250Hz, with a consequent slightly reduced output above 700Hz. It is suitable as mid-bass in line array systems or multiple way systems with high-pass crossover above 200 Hz and low-pass up to 3kHz; enclosure might be closed or vented with volume size starting from 2 lit. The speaker offers a superb linearity: distortion values are furtherly minimized by new enhanced design criterias, developed by Eighteen Sound engineers, taking the 6NMB420 to very high level of performance. The extremely powerful external neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. The levels of force factor and power handling are, as a consequence, at the upper professional level with best power to weight ratio.
