The hd M-Series are design column speakers with point source wave propagation characteristics. The elegant enclosures are made out of strength aluminum to prevent resonances in the audible frequency range and is available with different surfaces e.g. powder coated, anodized or varnished and numerous colors. This guarantees an unobtrusive integration into churches, conference rooms or theatres. The hd M-Series consists of the ultra compact model hd M2 that is equipped with two 2“ drivers for nearfield or speech applications and the slightly larger hd M4 as a fill loudspeaker in church applications or the hd M8 as a very compact main loudspeaker in conference or music applications.
