Description
CCM663RD
RD stands for Reduced Depth – so this speaker will fi t into tighter
spaces than the standard CCM663. A shallower cone and a redesign of
the easy-fi t QuickDogs™ frame reduce depth to a more usable 92mm,
while retaining everything that makes the CCM663 such a great inceiling speaker.
The familiar, yet discreet, dark blue Kevlar® cone of the bass/midrange
driver delivers a stunningly clean, detailed response. This, combined
with the pivoting aluminium dome tweeter for adjustable off-axis treble
response and three-position EQ, make this one of the most versatile
custom speakers around.
If preferred, the supplied round grille can be replaced with an optional,
square CCM663 grille.
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.
This icon indicates the size in inches of the speaker’s main drive unit(s). As a rule, larger drivers can produce lower frequencies for better bass response. They also typically have a higher maximum power handling.
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.
