I had a 2230 circa 1972. I had a pair of Epicure 10's and they sounded great up against the wall on bookshelves with the Marantz 2230. A friend of mine in high school back in 1978 bought a brand new Marantz 2285 and pair of Epicure 20's, this system sounded wonderful to us at the time and was the best stereo any of us had..
If it were me I would look for some old vintage speakers like smaller original Advent, JBL L-26 or L-36 (good for some reason on blue grass), Allison four, Epicure or EPI ten/100, etc..
