Creative SB X-Fi titanium rear speaker out (Black port) provides less sound than front speaker out my speakers are altec lansing acs56 (4.1) when ever I plug in the rear out port with the front speaker jack the front speakers also sounds less while at the same time the front out(the green port rear) is connected with the rear speakers the rear speakers provide full sound. And when I do the opposite connect the rear speaker with the rear out and front speaker with front out the rears are sounding less than the front. According to the spk manufacturer all of the speakers are full range. Besides can anyone tell me weather the Sound card is compatible with THX thanks
