JBL L112 speakers. Arguably some of the best speakers they put out before slowly going down the sink hole. I had a set, had them re-coned in 2001 and sold them for $1000 when I decided to totally revamp and get into a DAW.
If I were going retro, as for amps. I would go with a tube kit amplifier along these lines. Not necessarily this one but something similar.

I'd look for something around 40W per channel and < 0.1% THD. I like the warm sound of tubes. I'd actually be inclined to purchase schematics and source the parts myself and beef-up the transformers and main storage caps.
EDIT: If you decide to go with a tube kit, go with a push-pull type instead of a single-ended type. There will be a couple more tubes but, you'll get lower THD and higher power. Here's one with decent specs:
