HI Celtic
Very nicely written and you understand this speaker perfectly. Not many do but its a gem in ATC’s line up. Years ago I used to demo the SCM7 by putting it on a larger speaker, like a SCM40 3 way floor stander, at shows. Id play the SCM7 and people would ask how much for the floor standers, thinking that’s what was playing since they sound so good.. It was always fun to tell them "no, its the little ones!"
The SCM 7 was a project by Billy Woodman (ATC founder chief engineer) to build statement speaker that "defined" British Hi FI: extreme fidelity in the smallest package possible and not deliberately roll off bass. The expeince of Billy was tthe LS3/5 era, and in fact he worked for Goodman’s Loudsaker company in England during the time when they were one of the three factories building LS3/5a’s for the BBC under license. The little LF driver in the SCM7 is massive, and is tested at 7Hz, 20V. You can see this test in the factory tour we shot on visit to ATC many years ago. Ben was holding up this little driver toward the end of the tour video, in the transducer build room.
