This might have been asked before, but I haven't seen anything about it yet. I just went over to SVS's new website (great job by the way) and was looking at the new pictures of the drivers. I found that in place of the original TV-12 driver for the CS-U the new SS driver was pictured. Is the new SS driver now the official "TV-12" driver with the original version discontinued? If so, putting the new SS driver in the CS-U and charging the same price as before is an incredibly large and generous upgrade (like with the improved driver for the CS and PCi series). Makes my want a CS-U now. If this is true, I'm surprised it is not mentioned in the "Latest News" section, as IMO it is big news. Another question I have is regarding the enclosure tubings. Besides the SS subs, are there any differences between the enclosures (thickness, strength, material) of the CS, CS+, and CS-U subs? In the CS-U info section it states the use of a new 50% thicker tubing. I assume the birch end caps are in all the subs from all categories.
