The new Omnimagnet Dual further refines bass performance with its linear LF response and exceptional timbre accuracy, while its new HF section with Torus-Ogive waveguide delivers smooth HF extension with outstanding imaging. The REVOLUTION XT 8F crossover uses low loss laminated core inductors and audiophile components throughout and further benefits from high purity oxygen free copper (OFC), silver plated wiring. The 49.4 litre REVOLUTION XT 8F cabinet houses the largest iteration of TANNOY new dual-cavity coupled reflex system, featuring separate cavities coupled internally by tuned ports. Bass energy exits from a tuned down-firing port between the angled base of the cabinet and the integrated plinth.
