Matrix 1 Series2  
Stand-mount/ Bookshelf loudspeaker system  
Product Summary  
Advanced technology of the order found in the Matrix series could only have originated in  
what is generally regarded as one of the most advanced loudspeaker research laboratories  
in Europe. Computer Aided Design has been utilised to develop the range enabling the  
engineers to simulate the building of woofers and tweeters, predicting performance. Matrix  
cabinet bracing provides an inspired answer to the adverse effect which the monitor cabinet  
can have on sound quality. The loudspeakers are finished in a choice of real wood veneers.  
The Matrix 1 Series 2 comprises one 6-in bass/ midrange drive unit with polypropylene cone  
and one 1-in metal dome tweeter high frequency tweeter.  
Laser interferometry was used to identify distortion by measuring extremely small movements.  
As a good indicator of unwanted cabinet resonances, this technique played a crucial part in  
determining Matrix technology employed in the series 2.  
Technical highlights  
B&W 's Tweeter technology ensures that the sound remains focused and time sensitive and  
that the stereo image is presented with unparalleled three dimensional accuracy.  
Driver protection: The method used for driver protection against excessive overload is  
simplicity itself. Once dangerous input levels are reached the patent APOC circuit disconnects  
the tweeter alerting the listener to reduce the volume.  
Simplified crossovers: In sophisticated loudspeaker technology it is true to say that the fewer  
crossover components there are the better. Crossovers are no exception. In the Series 2, by  
reducing the number, signal is given a more direct path to the drive units. This has only  
become possible because the drivers themselves are more linear and also cleaner in their  
reproduction and therefore needs less correction than was necessary in the original crossover  
design.
