So-called bookcase speakers are invariably satellites, because their modest di- mensions prohibit proper repro- duction of frequencies below about 100 Hz. If you are planning a new loud- speaker system, you could do worse than to opt for a subwoofer-satellites system. It is then, of course, best right from t...
