Description
CCM7.3 S2
The CCM7.3 S2 is a high-performance in-ceiling speaker for outstanding performance in
both theatre and stereo applications. Its sophisticated drive unit configuration features a
25mm(1in) Carbon Dome tweeter, a 100mm (4in) FSTTM Continuum cone midrange and
2 x 130mm (5in) Aerofoil Profile bass drivers. Its critically formed baffle is constructed from
glass reinforced ABS while its integrated backbox ensures easy retrofittable installation,
cuts down sound transfer between spaces and optimises sound quality.
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).
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.
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.
