If your going try to get the best out of them, you will require an upgrade in amplification. Efficiency is good, but with low impedance from the upper base to mid range combined with some notable phase values won't allow them to shine unless you provide them with something that can reach 4 ohms without any stress.
With that said, they measured quite well and if your enjoy a more forward sound, it should end up working quite well for you.
