Tannoy have really cracked it with the Mercury F4 Custom Floorstanding Speakers, offering the perfect balance between home cinema and stereo performance. The Tannoy Mercury F4 Custom has a 19 mm MDF front baffle for improved cabinet strength giving floorstanders the perfect weight and feel. Performance is further improved with the 2 low frequency coated multi-fibre paper pulp cone drivers. This technology offers much better separation with sound that makes the Mercury F4s the ideal choice for medium to large rooms, plus the 140w power handling allows the F4 Customs to fill these larger rooms with ease. The newly designed F4 Customs offer an overall improvement in sound quality over the original F4's, boasting better bass response, more detail and increased speed. The Mercury F4 Customs have bi-wire terminals allowing you to further optimise the performance of these classic, elegant speakers. As you would expect from Tannoy the Mercury F4s are magnetically shielded. Available in apple or dark oak finishes.
