Focal works.  Well priced for performance.  Easily found and returned.

If you like the idea of extreme clarity, resolution, and dynamics, I too recommend trying the ADAM S2V's.... I've got the S3H's, which are 3-ways.  They have a digital crossover, and parametric EQ available to you, if that appeals to you.  Many audiophiles don't like that sort of thing.   I love them!  I like the ADAMs better than the Focal studio monitors, although Focals are very nice, and more attractive.  These are not lifestyle speakers with Bluetooth.  They are studio monitors.
