I cannot answer the question, but I suppose the differences will be relatively minor. More generally, it is a good idea to have two small subwoofers rather than one big (unless you want HT bomb sounds), for a smoother response over wider area. Accepted wisdom seems to be that it is better to use them in mono rather than one per channel. I would also strongly recommend using a room eq like the Antimode 8033.
And indeed, the idea that Asian products are of inferior quality is nonsense. I have seen too many shoddy UK or US products for that (and also many very good ones, of course).
