LF-4315 低频扬声器

简介

LF-4315 15” (381 毫米 ) 的低频机壳专为影院应用设计。LF-4315 和传统 “摇滚”低音系统的不同之处在于它可以满足影院对扩展低频响应的要求。 根据高频系统的要求,LF-4315 可覆盖 30 赫兹到 500 赫兹的频率范围。

三个定制 400 瓦,15” 变频器专为影院使用开发。它们采用 4” (100mm) 音圈,120 oz.(3.4kg) 陶瓷磁铁和多通风极片 (确保低温运行)。较低温 度可以增加变频器的寿命,并且减少高功率下的功率压缩问题。低切极片确 保音圈在对称磁隙 (SMG)中运行,从而减少了二次谐波失真。变频器的支 架和音圈可保证在高功率下的低失真和高重低音。

机罩由优质中等密度纤维板制成,所有面板都有加强支架支持。内部和外部 端口开口都经过全辐射处理,确保气流在较高功率下可以平稳通过端口,防 止声音端口气流紊乱。

低音端口均匀地分布在变频器两侧,使通过变频器背表面的内部压力更加一 致。这样就防止了圆锥由于力量失衡而被错误地放置在一边或另一边,从而 减少了高功率下将音圈赶出空隙中心的情况。

机罩上部的 3 个 T 形螺母使得安装 QSC HF-75 高频系统或 MH-1075 中高频 系统更加容易。
