Before they go in the dumpster...

I found these in my parent's garage. I think they are old Radio Shack "Realistic" speakers that were part of a console system. The console, I hope, had some sort of EQ because they sound painful and as far as I can tell are beyond saving unless I were to perhaps use a wideband tweeter that will play down to 500Hz.

...but on the other hand, I hate throwing stuff out.













Top line is frequency response from the listening position
Bottom lines are nearfield individual responses of the components outside the box (6" away).

Combined response looks like both drivers are working full range, would sound awful, especially if tweeter is breaking up at the lower end.
What about some photos of the XO network?

Response of the midrange actually looks OK on paper, what did it sound like on it's own? might make a good cheap OB mid.

Photo 2 shows the elaborate crossover. aka, a capcitor in-line with the tweeter, I bypassed it when I took the response by itself.

for some reason I can't see your FR pic, a Bug?
anyway, I'd remove that horn thingy, damp the whizzer with some foam, and see how they sound running with the back off the cab...???

Same here, I can see the pictures, but not the measurements.

I guess you don't want to spend too much on new drivers or crossover.
I'd filter out higher woofer frequencies, with something like 2mh coil in series
and 50mfd cap in parallel. and tweeter level may be brough down a little with small value resistor 2-3 ohm. and of course I'd remove whizzer from woofer

Hmm............ thanks, though it still doesn't explain why............

edit: Weird! Now that I've posted it separately, the original displays for me.

So do you actually think these are resurrect-able with a proper crossover network? They might be useful in the garage (if I had a garage).

The tweeter doesn't seem to have any worthwhile qualities but I'll run some more tests. I was ready to toss them in the trash (well, maybe I'll save the woofers for some sort of desktop subwoofer system...but even then at 8w they probably won't last long.)

The woofer has less power than the tweeter, that's odd. It actually looks more like a full ranger.

[chuyler1]

What do you mean by less power? The woofer is run full-range while the tweeter just has a cap on it.
