There would be a subtle difference. If you did an A/B test of the two side by side you would say that the .V4 was better. But if you simply unplugged your .V2 and replaced them with the newer .V4 you would most likely miss the differences.

Not to say the improvement is not worth it, but the speakers you have are very exceptional
