901 series 2 speakers

Line arrays evolved from the stuff Bear Owsley was doing with the Wall of Sound that The Grateful Dead toured with. Contrary to what a lot of companies hock as line arrays, they're defined by a set of charactistics that cannot be achieved by cones and domes alone. Before line arrays, speaker were arranged to emulate point sources, usually poorly. Meyer Sound has a wealth of white papers available on the subjects of point source and line arrays. 

Here is a decent little kit for only $100... they'll enter you into the audiophile world decent imaging, fairly smooth and detailed.... I'm sure that you might want a bit more bass, but you can add a subwoofer at anytime.  I hope this helps. Tim

Bose 901's for $100 would be an ok party speaker.

One more thing, I knew a Bose engineer. He and a lot of his co workers are audiophiles. When one's "job" is to design Bluetooth speaker or an OEM car audio with $20.00 worth of parts, one does their "job" and go home and enjoy music on one's high end system.
