CM7

The CM7 produces the kind of breathtakingly lifelike sound that can command any medium-sized to large room, thanks to the harmony of the relationship between its genuine three-way driver line-up and its first-order crossover.

The speaker features a single FST® driver, the outer edge of its distinctive Kevlar® cone supported by the characteristic compression surround, specially developed for outstanding midrange performance. High frequencies are handled superbly thanks to the CM7’s Nautilus™ tube-loaded aluminium dome tweeter.

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 chrome 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 or Wengé, or a highly polished gloss black.
