If your speakers include a warranty, there's usually no point in buying an extended warranty. Most warranties cover speaker damage and problems for a few years after you buy them. And if your speakers are relatively affordable, your money will go to better use on a new pair of speakers. However, there are times when an extended warranty is necessary. For example, if you're buying a premium sound system for your home theater that costs $1k+, then the extended warranty will be a smart investment. However, be sure to shop around for warranties. Don't be quick to buy the warranty that the manufacturer offers.
