For Sale : Four 18Sound 6ND430 6.5" midrange driver
i am selling 4 18 Sound 6ND430 drivers .barely broken in . i started a new project and will not need them anymore.
used by many for open baffle midrange , do a search to find projects where they were used. this is the 8 ohm version.
two drivers for $198
four for $380
zaphaudio tested the 16 ohm version and had good things to say about them:
Excellent performing 16 ohm pro midwoofer. Smooth response and an extremely clean midrange. Very usable T/S parameters and excursion though somewhat limited bass extension for what is meant for woofer service. Very sensitive. It would make a fine midrange also. Lightweight neo magnet assembly with cooling fins. A couple of these paired up for an MTM and used with a subwoofer would make a reference level system. High value for this level of performance. Tested August 2008.
* 92,5 dB SPL 1W / 1m average sensitivity * 45 mm (1,77 in) aluminum voice coil * 200 W AES power handling * Neodymium motor assembly * Weather protected cone * Improved heat dissipation via unique basket design * Ideal for compact two way and multiway systems
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. 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 6ND430 far more resistant to the corrosive effects of salts and oxidization
