But many audiophiles will tell you that the performance criteria for THX doesn't really concern themselves with sound quality. especially the surround speakers (THX dictates dipolar instead on monopolar).
As usual, 'audiophiles' don't have a clue what they are talking about. THX is all about minimum performance standards and therefore 'sound quality'.
THX does not dictate dipole for the surrounds. Yet another misinterpretation of the facts and one of the reasons there is so much confusion over what THX is and is not. Note also that another myth is that dipoles were recommended to overcome limitations of Dolby Pro Logic.
I'm not going to reiterate all this stuff because its been discussed so many times already. I would suggest reading the THX site, the Dolby site, and search the web for articles and interviews with Tom Holman of THX (see the Pardigm site for one). After you've ingested all the FACTS, then make up your own mind on whether or not THX has any value for you.
