Application example

Loudspeakers used:

Impressive compact subwoofer, suitable for modern living room, where the audio system must be as discrete as possible, but performances remaining at  the highest level.

.Kalypso_4 uses our 4" subwoofer and two passive radiators tuned at 45Hz.

The result with active correction provides outstanding results besides the size.

(High-pass: 30Hz -12dB/Oct,  Low-pass: 100Hz -36dB/Oct, and +3dB at 48Hz - Q2.2)
