is a scam
, or allmost . i tried one for a friend and it does'n't worth more then 50$ (maybe not even ,but my friend paid 200:P) . is ,,home-made''. on low volume is ok ( just ok ) , but if you try to raise the volume a little bit he fails. dont let the weight fool you , is because have metal cases . the small speakers dont look to bad but are weak . i will stronglly recomend you : DON'T BUY IT . that price (2500 $) on e-bay , is their bs you'll notice , is nothing else about magnum on any other site,comment,review... . hope you read this before you spend your monney .
