have 5 speakers from my old panasonic SB-AK-87 system (fronts 6 ohms- 160W). The player and amp are unserviceable. need help to put them to use. Can I buy an onkyo or yamaha receiver and put them to use (Will it match?)

any surround receiver should be able to power your speakers if they are 6 ohms. I cant find anything on your model though.

All speakers(low ohm load is the sole exception) work with all audio amplifiers ever made...

6ohm is not considered a low ohm load.

Hi! I'm having a problem with finding a suitable receiver for my 6 ohm speakers. If you could answer, I'd be very grateful))
Panasonic SB-PM41, 2 speakers. Each speaker has 4 cords (+ high frequency, - high freq, + low freq, - low freq). But! All receivers I checked have no outs for that (yamaha crx-550, for example, has 4 outs, R+ R- L+ L-). Guys in e-markets say they don't know that sort of ancient speakers =)
Can I do anything about that? Is there any suitable receiver? Or maybe I have to buy an amplifier and a media-player? Maybe I can let the wires modify, can I?

You need either a bi-wire speaker cable, or a set of jumpers to go from the low to high speaker binding posts.

P.S. Examples of both can be seen here...

Perhaps, perhaps not. If the speakers are wired for bi-amping, as opposed to bi-wiring, they would not contain crossovers, and directly wiring the HF drivers to an amp would result in magic smoke. The OP needs to get a manual for them to be sure.

Maybe, but I doubt it...

P.S. I stand corrected, found the owners manual, via google, on the Panasonic website, the speakers do require an external crossover...

So, my speakers are bi-amp speakers, and they require an external crossover or an amplifyer that already contains it. Did I get it right?
Thanks a lot for your answers!

It's extremely unlikely that speakers would require an external crossover; that is extremely rare! Yours definitely do not!

You have two options. One is to just tie the two pairs of terminals on each speaker together with short jumper wires and run a single pair of wires to each speaker. The other is to run two pairs of wires to the speaker from each pair of amplifier terminals (bi-wiring").

I would not bother with bi-wiring unless you are running more than 15 feet (5 meters) of wire to the speakers. Just use #14 wire.

(do you mean "SP-BS41" ??)

It does appear that way, since they are dedicated to that system, the system uses a bi-amped amplifier output, and the speaker input connection instructions contain this warning:
Cords with white and blue tags are for high frequency.
Cords with red and black tags are for low frequency.
Incorrect connection can damage the unit.

Hi! No! I mean Panasonic SB-PM41. They are speakers from an old stereo system.
Unfortunately, they don't provide any possibility to use another wires.
Anyway thank you! Now I know my speakers do have a crossover (looked into specification))

Looked into specification. It is said, crossover's frequency is 1khz and 10khz. I guess that means it exists. And bi-amp amplifier existed too.
I'm totally lost:) I thought I could find an alternative for that unit and use the speakers I liked and considered quite good. I started to think they are not that good to make a hi fi system -)

I would really play it safe, and start over with a new receiver and speakers. There are better
choices out there.
