First of all I do not like Bose products. This was my first purchase and I only bought these because I was in Bogota and there was NOTHING else available. These were what I expected. No tweeter means there were no highs to speak of. I also found the bass to be quite boomy which is what I expect the general uninformed public would like. There was noticeable noise when no music was playing as well as a pronounced hum. I didn't bother to return them because nothing else was available. There are many other much better options out there.
