1971 - Sansui SP3500 or something. I clearly remember they were 4-way, 7 driver, with woofer size of 15". This was when I used to judge speakers by the driver count. They had nice cabinets with the lattice wood grills.
1973 - AR 3AX. Blew the tweeters overdriving or clipping with the Marantz 2270.
1975 - Speakerlab 7 home built kits. Ugly, and not that good sounding on looking back.
1988 - Bose RM3000 satellite/passive sub system. This began a dark chapter, and resulting low point as I went into early AV surround sound.
2008 - Epos M12.2 standmounts, with a couple M&K subwoofers left over from the AV period.
2012 - Revel F208. These are the first speakers I've purchased without the thought that they were an interim step. I'm thinking these will be my last pair, more because of age and health than anything else. Course if I had extra cash, I could see getting a pair of Vandersteen Quatros.
