Opis

The three-way centre channel speaker features a similar driver line-up to the CM9, including two 165mm paper/Kevlar® cone bass drive units and a Nautilus™ tube-loaded aluminium dome tweeter. In order to keep cabinet height to a minimum, the speaker uses a slightly smaller 100mm Kevlar® FST midrange driver. The quality of CM Series drive units has made it possible to use minimalist crossovers throughout the whole range. The resulting gentle transition between drivers avoids the unnaturally rapid changes in dispersion that bedevil more complex designs, while the high quality components, carefully chosen after exhaustive listening tests, ensure that as little as possible gets between you and the sound of the original recording. All CM Series speakers come with aluminium driver trims. Grilles attach magnetically, so there are no unsightly grille-mounting features to spoil the clean lines of the speaker’s façade. For the finish, you can choose either one of two real-wood veneers in Rosenut, White or a highly polished gloss black.
