They are designed in America, but built it china

What is the sensativity dB of these?

Sensitivity (1W at 1 meter) 92 dB

Can someone tell me the overall diameter of the speaker with the grill attached? Id like to fit these on a motorcycle but need to knowthe overall size

If you're looking to put them in a Harley faring, you won't be able to use the grille. My 07 Street Glide had 5" speakers behind faring and had fabric to cover the hole. I added 6.5" adapters and mounted some Polk DB651s and chose not to cover the hole but there's no way to use the grille.
