Description
The CCM683 is a true high performance ceiling-mount speaker. The
speaker features a 200mm (8in) woven blue Aramid Fibre cone bass/
midrange driver and an aluminium tweeter in a neat circular die-cast
chassis. The tweeter’s housing pivots for adjustable off-axis treble
response and the die-cast chassis provides extra rigidity that results in a
cleaner, faster bass. The speaker also has a three-position EQ switch for a
better off-axis response. The blue Aramid Fibre cone means that the unit is
well hidden behind the grille but still produces a remarkably clear and
dynamic sound.
Speakers with the Cinema icon are either dedicated products designed for multi-channel surround sound systems, or ones which we highly recommend for this purpose. It should be noted that the majority of speakers are suitable for use as surround and/or Atmos channels, so this icon does not apply to that application, and instead focuses on front speakers and subwoofers.
Measured in ohms, impedance is the resistance or load that a speaker puts on an amplifier. When multiple speakers are connected to an amplifier channel in parallel (doubled up on the terminals) this actually has the effect of reducing the total resistance (1/Rt = 1/R1 + 1/R2 …). Most amplifiers are rated at 4-16 ohms, so care should be taken to stay within this range. If the total impedance in parallel is less than 4 ohms then the speakers should be wired in series.
