From the EA newsletter The NM-410: The Ultimate 4 x 10 EA is proud to announce the introduction of our first 4 x 10, the NM-410. The EA NM-410 represents the state of the art in speaker cabinet design. The design of a 4 x 10 presented some unique challenges for John Dong, EAs cabinet designer. He wanted the volume that is associated with the 4 x 10 and the sound quality and clarity that EA is renown for. More drivers mean more volume. More drivers also mean more interference between those drivers. This compromise, between volume and a truly focused sound was, until now, a reality of playing 4x10 cabinets. The design goal of the NM-410 was to create a high power 4x10 cabinet that was loud and had a balanced and uniform sound at all points in the listening evironment. John was able to accomplish this through a number of ingenious designs. The NM-410 utilizes a side vented, M shaped Transmission Line, proprietarily designed Neodymium drivers, and exacting placement of the 4, 10 drivers to create a cabinet that is both extremely loud and presents a totally focused sound at any point in the listening environment. The side vented, M shaped Transmission Line vents adjacent to the side handles. The imported Poplar plywood and Neodymium speakers keep the NM-410, at a reasonable 77 pounds. The NM-410 is rated at 1000 watts, has a sensitivity of 103 db @ 1 meter and a stunning SPL of 133 db @ 1 meter. With all of the cutting edge design, technology and features such as its built in wheels, the NM-210 is truly the envy of the class.
