Do you have the subwoofer or just the satellite speakers? Also they would really benefit from a recap if you didn’t do it. The caps they used drift pretty bad and smear the mids.
Can’t help you on price. That would need to be discussed in the dollars and sense forum. They are really rare and with the sub are pretty flat down to 16 hz. You need more power than a receiver will give for the whole set up. I would you a pair of 200 watt amps with them. The 25 inch sub will can make you physically ill if you play it loud enough.
