I think if you want to use those speakers you need some DIY skills.
There are problems with those speakers.
First the electrolytic caps were of poor quality and it seems a lot have leaked and just about none have the correct values anymore.
Next I understand there are a lot of iterations of the crossovers.
As far as I can tell this is most likely the final version.
Next the woofer section has a problem. The impedance drops to below 3 ohms and the DC resistance of the coils are too high. This was probably done to prevent the amplifier frying. I would say that this design is almost certainly in resonance, as is common with low passive crossover points.
The good news is that these speakers are good enough to warrant restoration and modification.
The best approach is to make the bass section active.
To do this you will need another two channel amp comfortable with 4 ohm loads.
You will need an electronic crossover like this.
Now make sure the crossover is the circuit above.
Eliminate the three coils and two caps to the woofers.
Connect the woofers in parallel directly to the bass amp.
Eliminate the 80 mfd cap in the 8" lower mid circuit.
Now replace all the other caps with good quality new components.
Now connect the top three sections to the high frequency power amp.
Now place the electronic crossover between the pre amp and the two stereo power amps.
Set the crossover to two way and set the frequency to 200 Hz. Trim the volumes between the high and low sections to a balance that sounds good to you.
This is well worth the effort. With this mod the speaker is capable of +/- 2 db from 28 to 20 K Hz.
The bass section is low Q around 0.5 and is capable of very clean reproduction.
The speakers due to age and design are almost certainly not in usable condition at present.
