Application example

Loudspeakers used:

This very compact solution (3L) uses our Ø90mm wide-band, in association with our Ø120mm passive radiator to re-produce 58Hz at -6dB.

Sound is natural, far from most of colored wide-band solution

Additional RLC passive filter (or any DSP tuning) provide more lineal frequency response.
