Hi Nap, thanks for your feedback. I do not have the ob1i, as such I am not able to experiment.
Levi, I am thinking of getting a ob1i but I would not have much space on the rear wall. I suppose 1 foot is about the maximum I can place away from the rear wall and 3 feet away from the side. Would it cause boomy bass / adverse effect on the soundstage? I had been advied that the pmc does not need a very big room and wanted to have some users feedback. Thanks
