A hybrid absorber, developed by concept-A, to combine the functions of a foil absorber and a broadband absorber. With the performance of the low wave, a slightly higher resonance frequency and a broadband absorption almost irrespective of the frequency, we recommend the "x-wave" element as ideal completion of our system.

Technical data:
Broadband-resonating absorber with a cut-off frequency at 80 Hz
Depth 18 cm
