1990s speaker recommendation

Earlier this week I saw on my workplace bulletin board a good deal on some speakers that I remembered listening to for hours back in the mid 1990s when I worked at a series of HiFi shops. I tried to pick them up but was too late, but the incident got me reminiscing about speakers from that era and a quick look at my local craigslist shows a fair amount of inventory.

I'm looking for suggestions for a good pair of floor-standing or sub/sat speakers under $300 from this era. Style of music in our house runs almost the entire gamut. This would be complementing a pair of smaller a/d/s bookshelfs in our living room.

Please make recommendations of specific brands and models to look out for second hand. Thanks.

When you say "this era", speakers that were made in the 90's are just as diverse in sound quality as they are today. There's no "house sound", for lack of a better term. That said, I was a big fan of Mission speakers. You may be able to get a pair for $300.
Finding a good pair of speakers for under $300.00 (even 20 year old speakers) is a tough call, however you could pick up a pair of used Infinity Reference 6's for about that price. The Ref 6's had the Emit-R tweeter, a dedicated mid-bass coupler & newer IMG cones. Otherwise you could look for an older pair of restored Infinity Kappa 7's or Reference Standard 5's. My pick of that bunch would be the Reference 6's if you can find a nice, unmolested pair.
I like the original B&W 600 series - 602 standmounter for that price, not the 603 or 604 which go for much bigger money due to their excellent bass.

I like some of the classic Linn stuff from then too but prices will be high.
I picked up a pair of KLH model 6's for my vintage second system and they really sound good. I paid $165 and feel they are a steal for the sound quality they deliver.
Don't waste your money! For 300 clams, snatch a "brand-new" pair of Elac Debut speakers. The net is buzzing about how these Andrew Jones designed transducers sound crazy good for the price. Google them and find out for yourself.
