The Tannoy Mercury F1 Custom bookshelf speakers are, to put it in What HiFi? Magazine’s terms, “True gold”. The F1 Customs create an astonishingly good sound considering their price. They are so good in fact that we think they could hold their own against higher end £250 speakers. Carefully selected components are incorporated into the engineering and design in order to reproduce the best sound possible at this incredible price. The F1 Customs are magnetically shielded which means your TV's image will not be affected if the speakers are placed directly next to it. The F1 Customs look exactly like the attractive Tannoy F1's but offer superior performance i.e better bass response, more detail, speed and overall quality of sound. These high quality, fantastic value for money speakers from Tannoy come in either an apple or a dark oak finish.
