JBL's Control Now speakers work great alone or in a group of up to four units. Each speaker is a $250, 90° wedge that is bought one at a time, and you can sit them on your desk, install them up against the ceiling around your room and even replace your ceiling fan with four Control Now speakers joined together for 360° of sound. Buy a pair and keep them separate or join 'em, join three, four — whatever your needs.
Under the hood, each speaker has two subwoofers, as well as a tweeter capable of pumping out over 100 decibels of sound. If you don't mind paying a little more, the Control Now line also comes in a weatherproof version, in case you want to mount them outside.
