Need some surround speaker selection advice Ive read a few articles about setting up a system with dipolar surrounds versus forward-radiating surrounds, but Im hoping I could get some further insight from the forum crowd. Im building a 5.1 system for now and want to make sure I start out right! Do you need a perfect room in order to get the benefit of a dipolar surround speaker, or can one achieve a decent sound field with the more traditional forward firing surrounds? I can save about 50% by going with the traditional speakers Are the dipolar really worth the extra cost, or should I use the money saved elsewhere??
