Title: 1 3/4"
Review: To properly install these, drill a hole with a 1 3/4" circular hole drillfits fairly perfectly into the hole and then you have the speaker properly flush mountedas soon as i get them, i will be installing these with a passive crossover, http://www.amazon.com/gp/product/B004BFQWPM/ref=oh_details_o01_s00_i00along with some power acoustik 6.5" midranges, http://www.amazon.com/gp/product/B000PKMCEW/ref=oh_details_o04_s00_i00Will leave an updated review with my thoughts, if it doesnt sound right they sell 1 and 2 microfarad non-polarized caps @ radioshack that will effectively block any lows/mids
