I previously had a subwoofer unfortunately boomed from BOSE and in the long run was not fun. Bose out - Nubert purely --- everything was great! No more humming, no roar. Clean, clear bass leave the home theater heart beat again. After a short telephone conversation with the Nubert service and a few Einstellungstips everything was perfect!
I have become absolute Nubert fan and can recommend the subwoofer each.
