Our newest speaker design produces an extremely smooth response on and off-axis while avoiding the phase and lobbing issues associated with standard 2-way designs.

They also outperform single full range driver even those with a whizzer cone added to supposedly improve higher frequency production.

Commonly used DUAL Concentric driver in Loudspeaker design.

This Quasi Coaxial technology used in all Sofia line loudspeakers get same time alignment, like a real dual concentric driver, but we’ve designed it to get even greater linear frequency response.
