as said, the controlled sound dispersion pattern of THX speakers can really help in bad (normal) room acoustic situations and produce better imaging results than conventional Hifi/High End speakers. So, don't wonder if you feel comfortable.
I just wished there were more THX "active" speaker choices, like the M+K 150Ps and more money would be spend in the driver technology or better, more rigid cabinets (like a B+W 802/801). Also, from time to time one runs into comments that the symetric driver arrangement is not the optimum for good music reproduction (some THX speakers, like the M+Ks have 2 or 3 tweeters). I will also try to read further into this topic as I find it very interesting. Personally , I have more a hair with the THX "dipole surrounds" by now then with the THX mains.
However, since there are good speaker alternatives available, non THX (unfortunately also often more expensive), but with excellent controlled radiation patterns as well and an almost perfect music reproduction, the chances are only slimm I will/would ever jump on the THX train.
