Okay, you asked for it!We need a photo of the amp. Some of us love the breadboard look!
The open look! Nothing wrong with 2w. Right now I am listening with 46 SE amps which are 1.25 watts. High efficiency speakers are the only way to go. You can’t use amps like these on Wilsons or Magicos. To quote Mr.T—-Pity the fools!Okay, you asked for it! View attachment 12477

I believe auditorium 23 /ligno lab did make them but azzolini audio do make them and are 3d printed.Where the heck do you find Altec 32b/32c horns? They seem to be as rare as hen's teeth. Is anyone making a replica?
I'm actually midway through the process of modifying a pair of cast aluminum 32's to optimize the throat. Original WECo 32's had 3/4" inch throat opening (for 713 driver), and hence needed a longer horn path to achieve proper expansion when compared to a native 1" throat horn. When Altec got hold of the metal 32's, they just bored them out to 1" to mate with 806/802 type drivers, but the problem is there's a bit of the throat (from where it was originally 3/4" to where the horn expansion would naturally open up to 1") that has parallel sides--in fact, that bit is cylindrical (which can't be optimal for horn expansion). Furthermore, Altec bored them at a slight angle, so now you have the smooth expansion inside the driver meeting, at an abrupt angle, a cylindrical section of horn before continuing on with the calculated expansion. I'm guessing this can't be optimal. When Altec made the plastic 32's, they reconfigured them as native 1" throat horns, which is why they're a little shorter than the aluminum ones.The consensus seems to be the plastic ones have the better throat...
Are you going to use Sals boost network? I'm interested in your R values there. I ended up goosing mine pretty high, so it seems.Will do once its done and all settled in!
Yes, I did have 16 ohm but one diaphragm needed replacing so I went with 8 ohm to keep it simple.Are you going to use Sals boost network? I'm interested in your R values there. I ended up goosing mine pretty high, so it seems.
Let me check tonight and I'll let you know what mine are. I forgot, my 802's are 16ohm... will need to convert for comparison purposes.
I've got ebay searches in place, but these horns seem to be going for crazy money (e.g. $700+).I believe auditorium 23 /ligno lab did make them but azzolini audio do make them and are 3d printed.
Much cheaper to keep an eye on ebay though. The consensus seems to be the plastic ones have the better throat...
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've got ebay searches in place, but these horns seem to be going for crazy money (e.g. $700+).
