Found a pair of Altec Lansing Model 14 in perfect shape with original boxes. One-owner pair bought in 1979/80. Woofers have been refoamed and look right. They sound good. Seller wants $1000 firm. I like horn loaded speakers (e.g. Klipshorn). Prior reviews on these look mixed. Any current opinions on the speakers and/or price? Are these a difficult model to find? Thanks!
