Monitor Audio CWT 140, CWT 180 User Manual

m o n i t o r a u d i o . c o . u k

Introduction

CWT speakers have been developed to provide synergy with Monitor Audio’s other custom ﬁt and home speakers. We apply our innovative design skills and experience in making high-end hi-ﬁ and home theatre speakers to the custom ﬁt environment providing un-rivalled performance and reliability.

The new CWT series offer versatile installation options for both in-ceiling and in-wall applications. This high performance range of loudspeakers has been created to provide ﬂexible installation in stealthy ‘trim-less’ round or square grilles styles. Featuring proven technologies and unique design features. CWT models combine high efﬁciency and wide frequency range to facilitate ﬂexible system design across a wide range of demanding residential and commercial installations. The CWT 140, 160 & 180 bass drivers feature MMP® II cone technology coupled with Monitor Audio’s trade mark C-CAM® gold dome tweeter. High frequency performance has been enhanced further by recent improvements to our C-CAM tweeter, taking the frequency band way past the limits of human hearing. The pivoting tweeter can be directed towards the listening space to provide ideal imaging and reduce un-wanted reﬂections when installed close to corners or wall boundaries. Simple crossover design implemented using high grade audiophile components to preserve the signal and provide a smooth yet detailed character.

All models have been designed to be less than 100mm (4”) deep, which means both round and square grille styles can ﬁt into a standard stud wall, or where mounting depth is restricted. By integrating the bass driver basket and frame, our engineers have managed to reduce the overall size by around 25% compared to its counterparts, whilst maintaining the same driver size and performance. Grilles are held in place magnetically by high power Neodymium magnets which provide simple installation and servicing. Since the sub structure for the units are identical, it’s possible to change the grille styles from round to square (or viceversa), should you so desire by simply removing the magnetic grille and replacing with a new one.

The grilles can be painted. It is recommended that a spray paint is used. If this is not possible, use a paint brush in a dabbing/ stippling technique rather than a conventional stroke. Also, do not over load the brush with paint, the grille holes will get clogged up.

Prior to painting, remove the inner scrim from the grille. A spare is supplied to replace this when the paint is dry.
