I’ve had a pair of the wonderful A25 speakers for 40 years or more, and they are still wonderful. Unfortunately, in moving several times and connecting and disconnecting the wires, somehow the positive (red) terminal on one of them got damaged.
The entire thing is loose and can’t be tightened enough now to hold a wire. The nut below it seems to be pushed through the recessed pad. Even using a banana plug doesn’t work.
There does not seem to be any way to open the back. There are four recessed holes in each corner, but they seem to be filled with some wooden plug. I scraped one out, but no screw under it. Besides, even if there were screws, it does not look like the back comes off.
Opening the front grill, there also doesn’t seem to be any way to get to the back.
How can I get inside the cabinet? Anybody know any way I can replace this terminal or find any other way of connecting a wire?
What does the terminal look like? These push on fasteners are useful for sabilizing loose rods, but I’m not sure that’s what you have. A trip to the parts bins at a hardware store might turn up just what you need.
You should be able to pop the front cloth off and then unscrew the woofer. You’ll probably need to push your way past a bunch of fiberglass (itchy!) batting to get at the terminals.
Thanks, I looked at tje woofer, but was afraid of what might be behind it. Would assume that, other than the insulation, there would be just wires. Just a few screws holding it, so will give it a try, not much to lose at this point.
If I ruin it, please post your address for my lawyer.
I thought there may be some construction details available that would help you get into the enclosures without damaging them but this is the best I could find. Not a whole lot of use, really.
Removing the woofer is almost certainly the only way into the box. There will be a pair of wires that go into the woofer from a bit of circuitry (the crossover, which determines which part of the signal goes to the woofer and which part goes to the tweeter). There will be two wires going from the terminal posts into the crossover. All you need to do is have the speaker wire connected to the wires going into the crossover from the terminal posts. Using the terminals is generally the easiest way to do this, but worst case you can poke the speaker wire in through the back of the speaker cabinet and use a wirenut or whatever to connect to the appropriate wire inside the speaker.
Wow! I’ve got the same speakers down in my basement. My father bought them in the early 1970s, and I used them from the mid-1980s through the mid-1990s. I should pull them out again and see if they still work.
Thanks, that makes sense and will try it tomorrow. In fact, think will solder a wire inside, then thread it outside and use the wire nuts there to connect.
Thanks to everybody else who had suggestions.
When I bought these speakers decades ago, they were a real bargain for 10" woofers and had amazing sound. I’ve move on, but still use these with an old receiver in my office, and they still perform admirably.
For any old time hi-fi phreaks, I also built a Dynaco amp and a preamp, the first of the solid state ones. Lots of fun and they also were outstanding. Only reason I left them was because they did not have enough inputs when CDs and such came along. Most people felt the old tube jobs had a warmer sound.
