Meridian DSP5500HC  
The DSP5500HC is constructed with steel panels sandwiched between the  
rigid inner cabinet and the veneered outer panels on four sides. The two  
200mm bass drivers are housed in separate internal enclosures. A third  
internal enclosure houses the tweeter and midrange. As a result the acoustic  
cabinet is extremely rigid, giving the benefits of extension, clarity and dynamic  
range unheard of in conventional centre channels.

Magnetic shielding with heavy  
steel prevents disturbing TVs  
Maximum output level up to 111dB

Meridian also included innovative DSP technology to compensate for boundary  
and corner use. This is a centre speaker that can be installed in almost any  
environment with confidence.  
The DSP5500HC has been designed to work coherently with the Meridian  
DSP5500, DSP6000 and DSP8000 loudspeakers.
