CCM664SR

The CCM664SR is a dual, two-way ceiling speaker featuring a 150mm(6in)
woven glass fibre cone bass/midrange driver and two offset soft dome
tweeters. The twin voice coil bass/midrange driver and tweeters allow
a stereo signal to be combined to facilitate the use of just one ceiling
speaker in a single installation area without the loss of one audio channel.
The CCM664SR also includes a two-position stereo/surround switch to
instantly make the speaker very suitable to be used as a surround channel.
Incorporating QuickDogs™ and plug-and-play functionality it is quick and easy to install.

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.

These speakers are single stereo models. They feature dual tweeters and separate left and right inputs to provide stereo sound from a single speaker. They are a popular choice for smaller spaces like bathrooms and en-suites. This type of speaker must be wired back to an amplifier using 4-core cable.

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.
