I have an SVS 16-46PC subwoofer in excellent condition. The unit has been used in my HT system for about 4 Years. I do not have the shipping boxes so it would need to be a local pickup or perhaps I could meet you close to Houston Texas. I have pictures that I can send to interested parties. The list was $849. Asking $375 OBO. Google the name and model and read the Sound Stage review.
Thanks
Jack
