That crossed my mind as I was looking at frequency graphs last week.GregBe said:...I think especially if you cross the speakers over at 80hz there is not much going on with a typical port anyway...
For example I was considering the Epos M5. The graph from Stereophile is below. The port tuning frequency is at 52 Hz. The output at that frequency with a 12dB/octave crossover should be down about 7.5 dB. I agree with you that its worth giving it a chance anyway.
