I had a double advent stack in my early twenties. I still miss them. Talk about bang for the buck. I was assembling Dynaco kits to power them. My neighbors all knew I had them. They did have a few faults but at that price (about $130 bucks/pair) they were hard to beat. Doubling up the pair just magnified their strengths. I still have one pair of them in the closet, can't bring myself to get rid of em.
They were my first 'real' speaker.
