There are a lot of good THX speaker systems on the market ... it's your budget and room size that matter.
The object of THX is to assure the consumer that the speaker will work as intended ... adequate SPL, correct off axis response, correct dispersion, lack of center channel lobing, adequate bass SPL, accurate frequency response, etc ... exactly the characteristics required for music playback in a multi-channel system.
You need to determine if your budget/room require (or want) THX Select or Ultra and then you can shoot the moon from the relatively inexpensive Atlantic Technology systems to JBL Synthesis or Triad Platinum.
