Description
CWM664
The CWM664 is an in-wall speaker distinguished by its 25mm (1in) soft dome
tweeter. It brings smoother and more detailed high frequency performance
to a package that also includes a woven glass fibre 150mm (6in) bass/
midrange driver and three-position high frequency switch to fine tune the
sound. Installation is catered for by a simple and effective QuickDog™ fixing
system. The CWM664 is an elegantly engineered and cost effective route to high quality in-wall sound.
Passive speakers must be powered by an amplifier. A passive speaker has positive and negative inputs which must be connected to the output of the amplifier with 2-core speaker cable (4-core is required for dual input single stereo speakers).
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.
Speakers with the Music icon are suitable for stereo music systems. Single mono speakers which are packaged individually and indicated by the ‘Single’ icon must be purchased in multiples of two when connecting to a stereo amplifier.
