A friend of mine is considering purchasing a pair of bookshelf speakers. Because of the room layout, the speakers will be close to the back wall. I want to suggest to him to either get sealed or front-ported speakers, but thought I'd check here first. Does the location of the port really matter, or will he encounter placement issues regardless of the type of speaker?
I should also mention that no sub will be used, so it would be nice for the speakers to get down to around 50 Hz., I guess.
