I don't know the model you refer to. You should dig around in the archives (i.e. do a search) on the High Efficiency Speakers board at AudioAsylum.com or better yet at the Lansing forum at audioheritage.org (for all thingsLansing, Altec, and JBL).
FWIW, I have a pair of the Altec 19s Xiekitchen mentions. They are great with tubes, and probably much better in a big space than a small one. My feeling is that they could be better with a bit more emphasis in the top octave (supertweeter territory) but they great as is.
