4 INTRODUCTION: WHAT IS A HIGH END IN-WALL? The new Snell AMC series units bring a novel approach to the design and construction of in-wall loudspeakers, expanding the boundaries of in-wall performance. Our primary goal was to develop loudspeakers that deliver ed performance that was as close as possible to that of our highly regar ded freestanding[...]

5 PLACEMENT OF THE FRONT CHANNEL SPEAKERS A home theatre system includes thr ee loudspeakers placed acr oss the front of the listening r oom. The distance between the left and right speaker s determines the width of the ster eo image. If the speakers ar e placed too close together , the image will be too narrow; too far apart and the blend will suf[...]

This is preferr ed over back wall mounting for several r easons: It places the surrounds at l[...]

This unique Snell feature provides the opportunity to toe-in conventionally mounted in-wall systems or compensate for the less than ideal placemen[...]

Be sur e the speaker wire does not rest or rub against any sharp or pointed objects. The speakers should be mounted on a flat surface to form a good seal between the speak[...]
