I quickly bench tested both a while back and I meant to get back to it, but haven't yet. One works for sure and is good and loud. The other one drew heavily on the power supply, but no made sound. I need to open it up and see if I can free up whatever is frozen in it. I will try to get to that later today and then get back to you. Shipping should not be expensive, because they will fit in a flat rate box.
