Excerpt: This is a third set of rock speakers I bought. I bought one pair of TF11 and one pair of TF5. I love the quality and sound coming from these speakers. We use them for outdoor church service purpose. I love the new design speaker grill, they look seamless and very nature for the outdoor environment. Very reliable service from this company, always on time delivery. Easy to do business.
Summary: The speaker cone for the dual driver eventually degrades due to cheap materials , despite being in a sealed housing . Also,. the granite coating flakes off and reveals the plain housing after about a year . Needs to be better constructed to last more than a couple of years.
