I didn't know you could take a duplex apart like this:)

HF drivers and the horns from a pair of 617 duplex. I have never seen a pair taken apart. I have been curious if Altec took a basically off the shelf pair of 802/806 and bonded them on to the 416/515 to make a duplex. I think the 617 is something similar to my 616. 806 HF with something besides 416 as the LF

here's a thread about the drivers.

if you put one of these sets and a 515G in an 817 i wonder how it would work out

The 617 HF wasn't a feather in Altec's cap. It was a University T50. I'm working on ways to improve that as it kinda sucks, and impossible to fix.

I just didn't know you could take one of these apart like that. I figured you would destroy the drivers getting them apart. Maybe its different with the T50. I know on my 604G and 616 duplexes, the HF driver almost looks like it molded on. Its probably just the paint. I see no way of taking them apart. Probably if the cone wasn't there the screws would be accessible.

How are the individual 515 and 802 constructed versus a 604. Is the LF section of a 604G significantly different than a 515b? I'm just wondering if Altec took basically finished drivers and built the 604/605, or if early in the production process there were some changes made to make them fit

Nah its all good. I would love to hear one of the Stanley Screamer 817's with the dual 604 drivers and the large format horn on top. I just think how much money you would have in drivers in one of those nowadays
