That is quite a change. You will miss the punch of those horns. The highs will have a very different quality in all aspects. You should listen to them, before you decide.

Whether your chipamp will drive them well, depends on your power supply and heatsinking. 4 Ohm speakers are always a tough load. With the LM3886TF you should not use more than 24 V rails, max ~30 V for the T package, and ~22 V will be the limit for the LM4780.

It also depends on your listening habits. If you listen at low levels, the chipamp might work fine. If you want to push it a bit every now and then, rather look for a different speaker with 8 Ohm and higher efficiency. Or consider a different amplifier.

The strikingly flat impedance curve looks, as if these speakers were designed for a tube amp.

Either that or a transistor amp that works stable with 4 Ohm loads.
