Disregard. My bad

I got this pair of speakers today. Cabinets appear to be homemade. But have these labels on the back. Search's reveal nothing. They do sound very good. Any info or thoughts would be appreciated.

Allen stopped selling a replacement 4ohm midrange. Their solution was a single 8ohm mid. Most likely why you only have 1 now.

Any updates? Did you ever figure this out?

One was blown and not working at all. The other still played, but I discovered warping of the diaphragm and burnt coil on the other. I don't have a "before" reference. I bought them off Craigslist and seller met me at a convenience store, so I did not get to listen to them in working g condition...

Reconed my tweeters with Chinese titanium domes....

Did you ever figure it out? I believe pin 1 of the IC is referenced as ground on the schematic

This all makes me very happy. I hope you gets enjoyment out of it, and I hope it inspires others to seek out and restore vintage equipment instead of throwing it away. Awesome job, and awesome write up . Keep the updates coming!

This is a transformer less chassis. Service manual shows test points for various signals, but does not specify a ground reference point. So where do I connect ground lead? Sorry if this is a noob question

They sound great with jazz, and blues, acoustic types of music. Really sound great with a sub added in. Pretty cool.......

Why you fill my head with these thoughts? I'm not going to get one wink of sleep tonight.....must double the efforts.....haha

The hole is approx 3" in diameter. 4 inch voice coil. As planning to use a peavey 22xt compression driver with a 6 inch round wave guide

Really just like to build stuff, and it seems this may be a pretty cool project. As far as I can tell the biggest coax is 15 inches and $500+

I initially thought about aluminum, but then I wondered about the aluminum expanding more than the iron if I drove it hard and got it hot. I have 2 of the black widows, and 2 or the 22xt compression drivers, and just thought this might be a cool project. I am by no means an engineer. Maybe the...

I'm thinking about turning a Peavey Black Widow 18 inch woofer into a coaxial

On a speaker with a vent hole in the pole piece. If I were to place a piece of ferrous metal in that hole would it affect the magnetic field? Please bear with me on this. I am going somewhere with this..... And,yes,before you say it.....I know that it will have an affect on cooling and thermal...

I have never heard of this. Kinda feel like I've become part of the joke.....:) Where is the build thread, or pictures, or videos, or something. I am intrigued

So that Frankenstein cartridge setup is functional? I'm still assuming the led was poking fun? Certainly meant no disrespect.

There are no words for this :jump:
