I needed to buy a sound system for local theater, and as part of it I decided to do some research into the various types of PA systems. It took me quite a long time and I spent a few months looking at magazines and surfing the web to see what I could find, and in the end I decided that the best thing for me, and in order to make a proper sound system for the theater, was to buy a set of Yamaha PA Speakers, mainly because they had such a really great reputation. I installed some I can honestly say I have never regretted the purchase.
