A single-driver in-ceiling speaker from Bowers & Wilkins. The CCM632 has one 75mm (3in) black glass fibre cone full-range driver and takes up less than a 150mm (6in) diameter of ceiling space when installed. This listing is a pair. Bowers & Wilkins says a single full-range driver sidesteps the problems of small two-way in-ceiling speakers, where the driver has to fire around the tweeter's body. Each speaker has an integral enclosure to minimise acoustic bleed into adjoining spaces. Driver 75mm (3in) full-range Frequency range 100Hz - 17kHz (-6dB) Sensitivity 84dB Impedance 8Ω nominal (5Ω min) Amplifier power 10W - 60W recommended Ceiling cut-out 120mm (4¾ in) Why you will love it One full-range driver The CCM632 uses a single 75mm (3in) black glass fibre cone full-range driver. Bowers & Wilkins says this gives a beautifully well-balanced sound without a tweeter sitting in front of a small bass/midrange driver. It lists a frequency range of 100Hz to 17kHz (-6dB) and a response of 112Hz to 16kHz (+/-3dB). ZipDogs fixing Bowers & Wilkins says its ZipDogs fixing method makes short work of installation and copes with almost any thickness of mounting panel. The speaker needs a 120mm (4¾ in) cut-out and 100mm (4in) of depth behind the surface. The integral enclosure means no separate back box is needed. Grilles and finish Bowers & Wilkins supplies the speakers in pairs, with round and square magnetically fixed grille and bezel assemblies. It describes these as fully customisable. The speaker is available in black and protrudes 5.5mm (0.22in) from the ceiling surface. Is it right for you?
