Background 
Today’s multichannel music and film soundtracks demand more performance 
from a centre channel than ever before.  High performance centre-channel 
loudspeakers must have frequency, phase and sonic characteristics that 
closely match your main speakers. When matched correctly, the resulting 
surround sound or enhanced stereo presentation will be natural. New higher 
resolution multichannel formats mean that correct choice of a centre speaker is 
even more critical. By designing our systems with mus ic reproduction foremost 
in our minds, Meridian has once again anticipated your needs with the 
DSP5500HC, matching the performance of its vertical counterparts. 
 
 
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. 
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.
