I am considering 5 identical direct-radiating speakers all around (+ subwoofer) for my HT/music system. It is my understanding that ported speakers give more bass than non-ported ones of similar configuration, while sealed speakers are quicker-responding. In other words, ported might be preferable for music and sealed for HT. If correct, is there really a significant, i.e. readily detectable, difference when using these different speaker types with music? With HT? Thanks.
