Speakers that are good with tubes

Tubes and horns are lovely together.

Do buy the Speakers first so you are 

not painted into a corner.

Many of the pitfalls users are describing that torpedo  tube amp performance are just poor speaker design.  So I'll add to my suggestions:  Buy a well designed speaker.

It does not have so be 8 ohms or above.  My speakers are 4 ohm, but they are very, very flat and very well designed.  I bought them to use with an ss amp.  The first time I heard them with a tube amp, I promptly sold the ss amp.

The boldened words are correct, of course. 

Using 4 ohm speakers is all good if your tube amp has a 4 ohm tap.

Otherwise not recommended if tube amp has a nominal 8 ohm tap which is probably OK for speakers rated between 6 and 10 ohms.
