I'm quite late to this thread but would like to add that...
I've been completely impressed with SVS customer service and their product after purchasing a full 5.1 system from them
Full tower mains, center, and 2 satellite speakers as well as a pb-12nsd
I fully will be upgrading the pb-12 for an ultra before my 1 year is up in the next few months, right after I get enough money saved again after the holidays.
This system will be used in my dedicated home theater. I cant wait to feel the power of the big boy.
I will continue to support and buy svs products in the future!
