Well, you sure have a point here!
Thank you very much for your wise opinion.
I was tempted by those speakers because they are at a very good price on ebay, and they have a separate body for L and R. The other speakers I could find are or on one individual block, and stereo makes not much sense if you cannot put L and R at your left and right, or terribly pricy.

I guess I'll have to look more for alternative brands or models, again thank you.
