Has anybody heard of these? They are super cheap! ($150 each) Here's a link to the product page in their catalog. http://www.skywalker.com/itemdisplay.aspx?item=227954 I know a guy that is using one as a keyboard amp in his band and said it does the job nicely. I just ordered 2 of them so i'll let you know how they work out. My band wanted cheap stage monitors and this is about as cheap as I have ever seen for powered 12" monitors.
