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. |
