From automobiles to aeroplanes, NXT technology offers unique audio solutions across the transport arena
Whether it is low profile loudspeakers for automobiles, directly-excited interior panels for aircraft or flat panel PA systems for travel interchanges, NXT technology solves the design issues that exist with conventional technology while delivering sound of the highest quality.
Technologies once only seen in the home such as DVD players, 5.1 systems and hard drive-based music players are now entering the transport sector as consumers look to replicate the domestic entertainment centres on the move. This trend has stimulated demand for complementary loudspeaker solutions allowing drivers and passengers to enjoy high quality entertainment on the move.
NXT technology has many benefits for transport applications -
• High quality - wide sound dispersion capable of producing excellent, cabin filling sound
• Durable - robust, grille-less loudspeakers allowing for the development of external mobile home loudspeakers capable of withstanding car wash cycles and pressure washers
• Unique - flat diaphragms can be produced in innumerable finishes, creating differentiation within a flooded market of aftermarket loudspeakers
• Flexible - enhanced sound staging can be achieved using low profile loudspeakers that can be placed in locations not possible with conventional technology (headliners, sun visors, even the rear view mirror)
• Economical - NXT technology can also attract space and weight savings when employed in vehicle cabins, while the reduced component count can create potential cost savings
Furthermore, by using the interior trim of a vehicle as the loudspeaker membrane (direct drive) it is possible to reduce cabin noise as the additional holes required by conventional technology become obsolete
