I think these speakers may be great and compare favorably with some 2000 speakers like alk ST,asend sierra etc.
One thing that makes these speaker very afordable is that they are likely made in china. Nothing wrong to this, as china has been making speakers for a very long time, since many foreing speaker company have moved there to manufacture their speakers. The american speakers i mentioned could be built there as well and sell very cheap, but the owner/desinger choose a different route. So at the end, it depends what you value. For me, is all american, i try to avoid china make things, as i beleive we should support our country intead of making other rich. But it is economic trade, china stuff speaker cheaper, benifits from teh buyer.
