The cone size isn’t directly proportional to the frequencies that it can produce. Since most audio companies try to use common parts for better pricing/margins they will gravitate to common sizes. That is mainly because that is what is manufactured. The difference between a 1” tweeter and a 1.35” tweeter is super minor because they can pitch produce the same frequency range. But a 1” tweeter will cost less than a 1.35” because 1.35 isn’t used anywhere.
If you are worried about being too loud for the house you might need to switch over to headphones. If you listen at volumes that don’t carry through the whole house you can get different stands and put them next to your computer monitor. You can still be close and have the volume down so that it doesn’t carry through the whole house. You can have the L desk in the corner and have the monitor in the corner with the speakers on either side.
