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
