Altec, or as someone else said about another brand, Altec Altec Altec.
Specifically, the Altec 604’s. I use the C and the D. They are 101db efficiency at 16 ohms.
I’ve been using them for 40 years, but over the last 3 months with a Velodyne 15” sub, that has made a huge difference.
I drive the Altecs with a pair of the NY Audiolab Julius Futterman OTL3s that have been converted to triode by Jon Specter, a former engineer at NY Audiolabs. They are 90 Watts each.
