The CXI's are a coaxial speaker.. His grill will cover this pair completely. The CSI ( I hope you got a god price on this set) is a seperate. His grill will cover the 6.5 like the other, but not the tweeter. I don't recomend covering it, but having him make a bezl you can mount the tweeter and it's grill(painted to match) would look good, IMHO...
