Black Box continued to be used worldwide into the 21st century, and according to Pro Sound News was the
world's most widely used PA system. One FOH engineer used Black Box at Glastonbury in 2008 and commented that
he "had forgotten just how good that system was" With this and other comments from customers world wide, it was
decided to introduce a new version of this system, and call it Black Box II. Whilst the laws of physics which govern
speaker design have not changed, there has been a tremendous improvement in bass driver design from the point of voice
coil power handling, and the high frequency performance of compression drivers.
A 4 x 15" version of the V Baffle was the obvious road to take, and following the research into dissimilar bass driver
parameters done in the Hi-fi industry, Court installed two lighter cone drivers on the vertical axis, and two heavy cone
drivers on the horizontal axis. This successfully combined the impulse response of the 2 x 15" bin, with the sub sonic
performance of the 2 x 18" bin.
