Query: buyer

I opened the box and played some music and found out the bass speaker rumbling, sound like broken. I lowered the volume of the bass speaker and the use the two small speaker. I am very dissapointed wasted my money. This is a no no brainer in my part. I will not do it again. I just buy something in Wal-Mart get better deal.
