TANNOY CMS 401 DCe

hi I'm John Boorman I'm here today to talk about tonight laud speakers in nineteen ninety ten I took its dual concentric driver put it into the ceiling and revolutionized the commercial sound market this is the new improved version of that speaker the CMS three series that basically takes the dual concentric driver which if you'll see here in the center allows you to fire the high frequencies right through the center of the speaker uses this as the waveguide that basically allows us to give you a single point source sound system that gives you better off access response smoother response then using your typical coaxial driver what they've done with this particular driver newly improved is combined the two magnet structures and two drivers into one magnet giving us better phase coherence better time alignment to the driver it also they improved the waveguide to give us better off access
