After reading SV's FAQ's column, I'm as confused as you probably are. What did you get out of their explanation?
"4) What's best for me? Cylinder or Box SVS?"

I am reading into it that the cylinder type subs are much cheaper to mfg. and ship, and seem to be more efficient in their development of bass. So if you are comparing their box sub to their cylinder sub for the same price, you are probably getting more bang for your buck with the cylinder type sub, which is the sub they seem to be known for. Without doing a side by side test, I cannot say which is better. But SV did say "Keep in mind too that even one of our CS-Ultra cylinders can leave some other $3,000 18" woofer box subs in the dust." Wow, if this is actually true. Makes me want to go get one today. These subs are mfg. in an old warehouse in Youngtown, Ohio.
Quote from the SVS website: "At the end of 2003, SVS purchased a factory left vacant in the Youngstown Ohio area (an old car production town). As of 2005 we are working again to expand this facility and SVS-run production of an expanding number of critical parts."
Actually, Youngstown is an old steel producing town. Lordstown, about 30 minutes away, produces the Chevy Cavalier, Sunbird, and new Cobalt. Not sure who made that statement. They don't list an actual address on their site, but I'm sure I can find it on google.
My parents still live there, in a suburb on the west side of Youngstown, about 3 hours from me. Next time I go visit, I'll try to arrange something where I can demo some subs. I'll tell them about this site, and that I want to post an informative thread on their products incase they don't have a showroom. At least I don't have to deal with the return shipping issue while there. These SV subs seem to have a cult following on this forum. I know a majority of us don't have one of them, and since they are not sold in local stores, we really can't imagine how good they are. If anyone has any contacts there, or the actual address, let me know before I pay them a visit.
