You could also keep an eye out for Altec speakers that used the 32 horn such as the Model 15 and 9849A. The A8 used a 32 also but it hardly ever comes up for sale.

Hmmm. That may be the original Western Electric. I might pay the freight on those if I was trying to build a "driver" correct 753. It has a longer throat and may be better with the WE 713cd. The Altec versions should go for around $2-300 a pair... that is if this thread isnt bumping up the price. You used to see them on ebay about every other month if not more frequent but I havent seen any lately.

I wouldn't sweat it too much between the metal or composite version. I have both and I think the difference is negligible. Not the easiest thing to A/B. But if there is any difference in sonics its probably just a bit different and not "better". I ended up with the metal one just becauase I think they look cooler.
I'm all about affordable. I'm trying to assemble the required parts organically (just came across a set of 414z drivers and N3000 crossovers for a good price - once I have them in-hand, I figure I can move the crossovers along to help pay for some of the cost of the drivers).
 
Does anyone know what size wood screws I should use to attach altec 32 horns? Also for the Jensen 15", I guess they would be USA imperial.

I'm looking for some nice black oxide ones, all I could find at the hardware shop today were shiny zinc coated ones.

Thanks
 
This has been a great read here early on Easter while the rest of the family sleeps in.
So much to ask and comment on, but before I forget, RCA Nut, what is that insulation material you show inside those great looking cabinets? Is it a 700 series Owens Corning fiberglass? And if so, where did you source it. Locally the usual source here don't carry it unless you order a truck full.

I used Owens Corning 2" 703 panels. I got it from a Local company called Kamco that specializes in supply commercial companies in NYC for the building trade. Amazon has a 6pk for about $100 shipped.

It's worth noting that on a tip from a friend I contacted an insulation supplier just blocks from me here in town and while they don't sell the OC version, they have the same thing from Johns Manville. I don't remember the product number, but they were sold in bundles of 8, 2ftx4ft batts. That's what I used for my room treatments and for my Altec 614 boxes. Works great.

Maybe see if you have a Johns Manville distributor in your area. If you tell them you're looking for the OC 703 equivalent they will know what it is.

See, I've checked with the local distributors here and none of them are carrying that stuff. One of the fastest growing areas in the country , and they don't see the need to carry it. I gotta think someone has it. Ridiculous.

I'm pretty sure the product I got is Johns Manville 800-Series SpinGlass. It's sold as external duct insulation. Have you called this place? I'd try and talk with a rep...

GTS didn't have it when I checked them. I think they do have some 2.5" thick unfaced fiberglass in a couple different R values. I'll check back with them on the duct insulation angle.
