I was told the SV1212N has the same driver as the SX1212N.
The new S1212N has different driver than the SX1212/SV1212.
For a little "less performance and aesthetics" than the flagship SV1212N, I think the new S1212N is the best deal out there, especially if you can get at discounted prices
AND if you want a subwoofer with External Amp so you don't have to worry about having to replace the built-in amp like most subs.
So the new S1212 has similar performance as the SV/SX1212, but at less price.
