Wow! That's a pretty slick website. I'm definitely looking forward to reviews for the SBS line, and I'm looking forward to the other two speaker lines even more.
If you happen to visit the AVS Forum, you'll see a quick review by a member there who received this setup today from SVS. Seems quite pleased with the product.
Those subs haven't been shipping for months now due to supplier issues but we'll be bringing them back more than likely when we get another on board to build those low volume cabinets and we finish design on self-powered versions too.
So they are on hiatus, but I expect they will come back in the not too distant future.
