DD: Dolby Digital - Wikipedia, the free encyclopedia

DTS: DTS - Wikipedia, the free encyclopedia

Since THX is a peformance standard, it is unlikely that all speakers would have similar performance.

Yes you can use multiple subwoofers, but you can run into a cancelation of bass with more than one due to phasing issues. One kick butt sub is generally preferred vs multiple so-so subs.
