As the title says I’m trying to replace to speakers that were in a Bluetooth tower speaker. I’m a little confused on what size replacement I need. I have done some research but the videos olive saw just mix me up more. I measured them corner to corner and the tape measure says 5 inches. Now what gets me confused is many videos also measured the speaker itself the foam vs end to end. Is this truly a 5 inch speaker or am I completely mixed up again? I’m not worried about what the replacement looks like I just don’t want to order the wrong ones and have to do a return and cost more time and money. Any help is appreciated greatly! Thank you and god bless
