Altec 604 Duplex Speakers and related
Various series crossover networks are noted.
Opinion is only as valid as its verifiable supporting evidence.
Thanks, so, 604B was introduced the same year as I was. How nice to see it used a series crossover, N-2000, as did the later N-1500A and N-1600A.Originally Posted by mah
My Dad's 604B was wonderful sounding to me back in the day, when it ( and I ) was new !! Series crossover, LMAO !!!! Thanks Marshall, nice link.

Isn't that N-1000?

Hi OG,
Not according to mah's link, click on it and see. ( But then, I'm dyslexic !! ) See his URL referenced above please.

Sorry Jeff- read again. It says 604 used the N-2000 but you said the 604b does, it uses the N-1000
604
Network: N-2000-A (also N-2000-B) - series filter networks
604B
Network: N-1000-B crossover - series filter network

Hi OG,
Yes, I was hasty and mistaken on that point. Thanks.
Lotsa ALTEC-designed series crossovers with first order slopes in the early days, when amps were tube type !!

First order IMHO sounds better, but you have to really work to get it right. I'm lazy in my old age. Active sounds good and i can do it half asleep.
