The JBL Studio 590s were amazing speakers for the money.A highly engineered and sophisticated horn design which sounded superb with low powered amplifiers. JBL seems to have stopped making them however.
If you have the ability to do simple DIY, the LX521's are really superb. I made the Orions and was disappointed. The LX521.4 are really great speakers. From a very deep and tight bass, to a sublime midrange with excellent imaging, A little odd looking, but fantastic performance.
