CM Series

Introduction

CM Series

A new standard in compact loudspeakers

Launched in 2006, CM1 featured a high-quality cabinet, all-metal detailing and a range of luxurious finishes. It has set a new quality benchmark for compact loudspeakers.

Introducing the new CM Series

CM Series

Beautiful sound

CM Series

Best-in-class sound quality The new CM Series makes a great-sounding loudspeaker range even better. Every model in the range benefits from a host of detail and technology improvements. There is also a completely new model.

CM Series

Advanced technology Every model in the new CM Series features the new Decoupled Double Dome tweeter. All models feature Kevlar drive units. Three models feature FST midrange drive units. Two models benefit from tweeter-on-top technology.

CM Series

Beautiful design Every model in the new CM Series is as visually arresting as it is sonically talented. Available in a variety of high-quality finishes. Invisible grille fixings for a clean, uncluttered finish. Highly polished, all-metal detailing highlights.

CM Series

Wide choice of products With three stand-mount models, three floor-standing designs, two centre-channel speakers and a subwoofer the new CM Series offers an exceptional degree of choice.

Industrial Design and Technology

CM Series

All-new industrial design

New trim rings around drive units on models with no visible fixings. New, upgraded drive unit location into chassis featuring M4 screws. New steel tweeter grille mesh protection for all baffle-mounted tweeters across all models in the range, with a complementary design for tweeter-on-top models

CM Series

Tweeters – diaphragm

Dual layer tweeters are used in all models in the range. Tweeter diaphragms must be light and stiff to reproduce high notes accurately by pushing the first break-up frequency further away from the audible band below 20kHz. The dual-layer tweeter uses a thin and light aluminium dome reinforced at its periphery by a second dome with its centre portion cut out. This stiffens the visible dome without adding mass. The result is that the first break-up is raised from 30kHz to 38kHz, while sensitivity is raised.

CM Series 2

Note the comparison between a tweeter assembly approaching its first break-up mode and one exhibiting more pistonic behaviour:

CM Series 2

This dual-layer dome is combined with decoupling to create the Decoupled Double Dome tweeter. This helps prevent cabinet vibrations reaching the tweeter, which leads to cleaner, sweeter high-frequency performance. This is the same principle behind ‘tweeter-on-top’ design, as used in two models. In baffle-mounted applications, a ring of synthetic gel surrounds and cushions the magnet assembly, ensuring the entire assembly is able to float within its mounting.

Tweeters – decoupling

CM Series

In two models we use the full ‘tweeter-on-top’ configuration. The tweeter diaphragm is housed in an entirely separate enclosure. This delivers measurably superior performance when compared to both baffle-mounted conventional tweeters and decoupled designs.

CM Series

The measurements show a comparison between the directivity index of a baffle-mounted tweeter in a CM5 S2 versus the tweeter-on-top configuration of CM6 S2. The ideal directivity index would be a perfect circle. CM6 S2 clearly gets closer to that ideal state.

CM Series

The Decoupled Double Dome tweeter in all new CM Series models is the same component used in the new 600 Series. However, it performs significantly better in the new CM Series. This is because of the superior components used in every new CM Series model. This includes all-new crossovers with high-quality EVO capacitors from Mundorf, upgraded nickel-plated input terminals and superior internal wiring throughout.

Tweeters – crossover

CM Series

Bass/midrange drivers

All models use woven Kevlar cones plus energy absorbing Anti-Resonance Plugs (as found on PM1). These simple mushroom-shaped plugs are a tight fit in the voice-coil former and ensure it stays in shape at the upper frequencies of the driver’s response. The result of this simple change is a smoother driver response and less low-level coloration just above the crossover to the tweeter.

CM Series

Midrange-only drivers

All models use woven Kevlar cones.

FST drive units in three models. FST in CM10 S2 is fully decoupled from the enclosure using a drawbar mechanism.

CM Series

Bass drivers

All bass drive units in all new CM Series models use paper/Kevlar cones in a dark finish.

CM Series

Stronger cabinet

New CM Series cabinets are stronger (i.e better braced) than their equivalents in the new 600 Series. The animation (right) shows a velocity measurement across the front baffle of the new 683 S2 (top) versus the CM9 S2 (bottom) measured at 350Hz. The CM9 S2 is clearly stiffer. This delivers a superior platform for the drive units to operate from.
