A friend uses and sells the Beauhorn Lowther (top-end) speaker. He has had great success with the speaker. It is fast, transparent, detailed (but not overly so), coherent with good highs, mids, but limited deep bass (need a sub).
If I were going to low powered tube amp, this would be the speaker to try out. See www.soundsofsilence.com for more info and product links.
