Rockville RPG8 & RPG 15's are a hoax. Not a single testing lab label on either product. Garbage.
Does not perform in the wattage range advertised and apparently the product never could.
Imagine buying a speaker rated at a peak rating of 800-1000 watts and it's barely performing at 35 watts. It's mind numbing that this stuff is allowed to be sold on Amazon and the Rockville website along with other vendors. Commerce FRAUD! No call backs, no email responses no response from vendors when contacted through Amazon.
