Professional Studio Reference Monitor Subwoofer
Subwoofers often enough tend to disintegrate the sound image as they have to play with an unknown satellite partner speaker. Unknown means that the low pass filter of the subwoofer and the high pass filter (or behaviour) of the satellite speaker cannot be foreseen and consequently not be optimized.
HEDD Tower Mains complement each other. 4th order Linkwitz-Riley filters are applied on both units, the mechanical transfer behavior of the two speakers is taken into account. A minimum phase behavior and a homogeneous sound are achieved that way, even if the units are placed in slightly varying positions.
