Your options are, broadly speaking, traditional wooden speakers that have been the mainstay of the speaker market for years and give great sound. They are available as bookshelf, stand mounted or floor standing designs and can look very elegant. If your goal is excellent reproduction of music then they are still the best choice.
The most common alternatives are known as sub sat systems, as they use a subwoofer to produce the bass frequencies with satellite speakers for the rest of the frequency range. The advantage of this approach is that the bass can go deeper than in most traditional speakers and the satellite speakers can be small. Unfortunately they can sound poor if they are not designed well or if they are not set up properly in your room. We recommend sub sats, but only the best ones!
The third approach to speakers is the custom installed way, where speakers are fitted discreetly into ceilings, walls and even rocks in the garden! This is a great way to lose those boxes but it generally compromises the sound unless you buy the very best. They are ideally suited to bedrooms, bathrooms, pools or patios, where the ultimate sound quality is not the main requirement or the use of more traditional speakers would be inappropriate.
