Samsung HW-N950/ZA Harmon Kardon 7.1.4 Channel Soundbar Dolby Atmos CIB Complete in box. The subwoofer crackles at times. It doesn’t do it all the time. I understand that it is “blown” but it doesn’t make the sound all the time. I purchased this new and I’m the only owner. I’ve always treated my equipment with care and never cranked the volume. The rest of the unit is without issue. The only cosmetic issue is a scuff in the subwoofer. Will ship in the original box with the original packing materials. This is a large and heavy soundbar so plan accordingly for placement.
