If you do, then you'll get caught in that endless loop of buying the cheapest junk and constantly being disappointed. Consider investing in quality equipment with the plan that it should last a good, long time. Say five years. Search out equipment that not only meets your application's specifications, but also look for equipment that offers you the best possible warranty to assure a long and trouble free life. It's hard to improve on loudspeakers these days.
Competition is so fierce, few if any manufacturers are building out-right garbage.
But, it is easy to buy the wrong speaker. What sounds great in a retail demo room might not sound as good in front of the troops, staff or public. When it comes to loudspeakers, you really have to make your decision based upon the sound quality of the speaker in the environment in which it will be used. Since the speakers are going to be used in multi-purpose applications, the durability factor should be figured in after you've done all of your listening tests. No one wants an indestructible loudspeaker system that's inaudible.
