Duntech PCL25                 

The DUNTECH PCL25 Loudspeaker has been designed for the discerning listener who demands very accurate sound reproduction from a small package. And at an affordable price.           The PCL25 is faithful to the design philosophies that encompass all DUNTECH loudspeakers, and for which Duntech Audio has received international acclaim.           The technology is further enhanced by hand-crafted cabinets, which are finished in authentic timber veneer with acoustically transparent black grille cloth.           What makes the PCL25 better?           The DUNTECH PCL25 Loudspeaker is a two way, three driver design in which the drivers are arranged in a symmetrical fashion along a vertical axis. This creates a simulated point-source radiation pattern.           To achieve proper stereo-imaging and depth, loudspeakers must possess point-source radiation patterns when reproducing music recorded by microphones, which are themselves point-source devices.           Music as is should be heard           The sound from the PCL25 will arrive at your ears simultaneously. It will be low in distortion and sound extremely well-focussed, giving an almost transparent quality. So, the music you hear will create the feeling of "being there", as if your were hearing it played "live".           This is the ultimate benefit of DUNTECH pulse coherent technology... excellent stereo-imaging, depth and clarity.           And, when you consider the price of the PCL25 and the inclusion of a 5 year warranty, it all adds up to a remarkable loudspeaker package.                                                                         Time-aligned for greater music accuracy             The three drivers in the PCL25 are accurately time-aligned. This means the radiating centres of the drivers are exactly equidistant at the normal listening distance of 3.5 metres.             Accurate time-alignment of the drivers is one of a number of design features that Duntech has collectively labelled "pulse-coherent". Pulse coherency determines the ability of a loudspeaker to reproduce complex musical sounds without blurring or smearing. It allows a loudspeaker to faithfully reproduce sound as it is heard naturally by the human ear.
