Can a pair of smaller speakers and a powered sub really sound as good as a pair of larger speakers?
Definitely. In fact, there are some folks who prefer a bookshelf/sub system to tower speakers. You must be sure to choose bookshelf speakers and a subwoofer that blend well together, and you may need to tweak the crossover to get the ideal sound. But a bookshelf/sub system can deliver impressive, full-range sound without taking up too much space in your home.
