Speakers for 50W Triode tube amp


What would be your choice of speakers for a 50 W/channel triode tube amp? Consider efficiency, bass response, clarity, staging, etc.

Seriously consider Silverline since price wasn't mentioned.
One of the better speakers across the spectrum being very efficient without going to horns.

I have a Meadowlark Hot Rod Herron that works very nicely with an 18 watt Audio Note P2.
