[Help identifying speaker pair]

Hello,

our local senior center had a yard sale to raise money and I offered to help them identify more expensive donated items.

these speakers stood out big time.

can you help identify the year and model?

also any idea of value and a trusted sales venue to offer them in would be appreciated.

I know they also need to be tested before being sold.

Anything to look out for when hooking them up?

I have more photos but had to crop these to get below 2 MB. They are in showroom condition, with original covers.

thank-you so much for any assistance.

sincerely,

mike Stewart
