Monitor Audio Platinum In-Wall Speaker

The Platinum In-Wall 3G is a three-way architectural In-Wall loudspeaker that features an MPD III tweeter, 4” RDT III midrange driver and twin 6" RDT III bass drivers. It can be used either horizontally or vertically anywhere within a high-performance home theatre or two-channel stereo system.
Platinum In-Wall 3G is Monitor Audio’s flagship high-performance, architectural, in-wall speaker. It is designed for use in high-end audio and movie systems, where accurate, clear and lifelike sound is required. With the minimum of room intrusion but with maximum scale and sonic impact.
Platinum In-Wall 3G can be installed either vertically or horizontally, which means it can be used on any channel within a system and is ideal for LCR applications and for seamless tonal accuracy within a theatre system.
