I have no idea what either of them are but you may have some gems. Maybe not!!
The 1st pair look very promising!! They sort of have an Infinity look to them with the glare off the grill cloth. Probably not tho since the cabinets are not recognizable and do not look home brewed. See the bi-wired posts!!! I would go check them out. They also look to be bipolar, so the imaging should be great if the drivers are correct. Give them a listen and check the drivers out. If they are of that vintage, they may need work. Negotiate accordingly.
The 2nd, unless you can get them on the cheap, there is a lot of work going on there. Drivers missing. No idea what they are. The cabinets look solid. Could be a decent project for the future.
Just remember, If you can't test a speaker, it is probably dead. If you can and it is partially functioning, I only offer half of what the asking price is. Go with your gut. If it says NO at first, go with your gut!!!
