Should I?? Dahlquist DQ-20I for $200???

I don't know much about these speakers to begin with so I'm skeptical at this time. I can find plenty of info on the DQ-10's but nothing for these speakers. Does anyone have any info? The speakers look to be in good condition and sound good. My uncle is currently using them with an HK125 which I'm beginning to think isn't even close to the power they need.

I would like to use them with my HT setup. I currently have a set of Klipsch SF-2 and SC-1 center with a Yamaha HTR-5660 receiver. I know the Dahl's probably won't match very well but this one of those deals that's too good pass.

So, would I be wasting my money on these because I don't have the equipment to power them? I don't have the money to upgrade them or purchase another amp.

Would I be able to power them with a 6.1 Receiver? I saw there are 4 connections on the back so I'm not sure how I would hook them up since the woofers would probably need their own amp.

Any advise would be great. I have to let him know something next week.

Thanks!!!!
