monitor repair

hey there ppl, newbie here.....really like the forum btw!!

ave got 2 pairs of monitors which need repaired.....kicked the arse right out of them....

both are samsons......R6A = one speaker total distortion, the other only the high end coming through...

......R80 active = one speaker cut out and makes a popping sound and the other a think just the high end comes out....

think its safe to say that ive blown them 2 shreds....

was wandering if peeps have had to get there monitors repaired in the past and how much they had to pay?? or how much am i looking to pay...?

wanting to sell the R80's to a friend and to keep the R6A's......

both by the way are really good monitors!!

thanx!
