Not enough information to go on. need some other detail, at least one more relevant detail... to sort this out. an answer is only as good as it's corresponding question.
Looking for an old Stereophile review ...
There was a review in Stereophile 10-20 years ago about a slim tower speaker using pro audio drivers, very obscure company, presumably gone now. My recollection was the drivers were inexpensive, too, and the reviewer was very impressed overall. I think these were highly efficient, too. Anyone know which issue this was? Or the name of the speaker company and model?
