Midrange 8", 200W AES, 400W Program |  |
|
|
|
The MR8N301 is a high efficiency, high power midrange specially designed to provide superior sound pressure level in a very compact size.
The total weight is reduced to less than half of a comparable ceramic midrange thanks to an incredibly powerful neodymium magnet assembly. The unique sealed basket design doesn’t require a back sealing chamber, simplifying the cabinet design and improving heat dissipation. Every detail of this speaker has been optimized to offer the best response and perfect control to the midrange frequencies.
Applications
The MR8N301 is especially designed for horn-loading and line array configurations. The ideal range of application are mid and mid-high frequencies. The combination of the 3” voice coil, the neodymium motor and the heat sink basket design makes this driver the ideal solution for the most demanding applications. |
