Medium scale cinemas  
The Screen 4 is a 3-way system, with dedicated mid-range and  
high frequency sections. Developed by Martin Audio systems  
designers, this innovative solution overcomes the strenuous  
demands on the high frequency section of traditional 2-way  
cinema systems. By splitting the frequency band from 630Hz-  
20kHz into dedicated mid-range and high-frequency sections the  
Screen 4 produces superior, low distortion sound for  
small/medium scale cinema environments.
