    Exceptional bookshelf speaker for the price. Wonderful soundstage and tremendously smooth midrange.

  • Excellent with a but.....

    Excellent, but make sure u have lots of power. I was using 200wch power amp and it was kind of dull and lifeless. Then I use 400wch and put them far apart and wow, they are very lively and sound similar to the LSIM 707 floorstanders that I also own. Conclusion, only buy if your gears are high end, period. These bookshelves are more demanding to run than the 707s.

  • Best Bookshelf speakers in 2k range PERIOD
