Bowers & Wilkins CWM652 2-way in-wall system

Description

CI Cinema Detail with CWM8.5 Grille On.tif

CWM652

The CWM652 features a 130mm (5in) blue Kevlar® bass/midrange driver
housed in a die-cast chassis which provides the extra rigidity to provide a
cleaner, faster bass. Its aluminium tweeter incorporates a Nautilus™ tube to
absorb unwanted sonic radiation. The CWM652 also utilises a three-position
high frequency switch to fine tune the sound. The incredibly easy to install
frame includes QuickDogs™ and plug-and-play functionality.

 

 

.tagged passive

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).

tagged imp-8

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.

tagged music

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.
