I just got referred here from the Audiokarma forum. . . lovely place!
A couple years ago, I inherited a pair of Altec 604 speakers in 9 cubic foot baltic birch cabinets from a retired electrical engineer in Silicon Valley. I'm a musician, songwriter and producer of independent label artists, so I was fascinated to dip my toe into the aural world of the famous 604 sound.
Except for a strange frequency response difference between the left and right speaker, I thought they sounded amazing. The midrange detail was unlike anything I've ever heard. I was told the speakers themselves were 604 B and from the late 1940s.
Then things got more interesting. When I opened the cabinets, I discovered one speaker was, in fact, a pristine Hollywood 604B with beautiful N1000-B crossover network.
The second speaker turns out to be an Altec Duplex 604 20 Ohm, with no letter demarkation and a serial number in the 3400s. It is beautiful, has an accompanying N1000-B crossover network.
So, now that I know what I have. . . what should I do?
