  • Good Sound Quality with very good midrange performance
  • Can be oriented either horizontally or vertically without affecting dispersion or frequency response
  • Very good bass extension for a small speaker
  • Very smooth off axis response
  • Minimum floor space necessary when used with stands
  • Easy to move due to small size and weight


  • Relatively low sensitivity (inherent in small box speakers)
  • Must be elevated for best performance
  • Can bottom out if overdriven
  • Grille very difficult to remove
  • Best performance slightly off center axis


The Thiel SCS4 speaker system has certainly met my expectations for performance, and the amount of low end exceeded it. The SCS4 is a well thought out and well made effort. The materials and workmanship are both first class. The front baffle and speaker are cosmetically a thing of beauty, and the overall construction is excellent. The average user will find this system suitable for all but the largest rooms, and biggest amplifiers. If you have limited space, and the wife will not let you buy that floor standing speaker you really want, the Thiel SCS4’s can provide you with years of excellent sound and aesthetics to please the true audiophile in you.
