Summary: I am very disappointed with this purchase. The speakers themselves are very light which is good and why I bought them. The sound is OK, nothing spectacular. However, they don't last! I ordered two 15's in September '12 and have already had to replace one. I also recently had a 12 (which I purchased in January '12) just stop working, since its out of warranty i'm left searching for a repair shop. DO NOT BUY MACKIE PRODUCTS!! THEY WILL NOT LAST.
