The sound quality is also affected by the how well it was installed or placed, quality of the head unit and/or outboard amplifier, and other add-ons such sound deadening.

Remember that sound quality is mostly subjective.

My recent speaker journey...
Had to swap old, torn, too far gone stock speakers. Genuine replacement was ruled out. Wanted some improvement.
Thing w/ online sourcing, one will leave a lot to guesswork....besides speaker diameter & cost.
Measured stock ones up, shopped & took the risk. The new speaker depth>stock & the mount holes were off those on the door. A bit of surgery, spacer fab were needed. To retain stock screw mating, the stock housings were cut away from the old speakers....to be adapted to the new. Measured the needed spacers to keep the magnet from touching the door's sheetmetal.
Pics of the door speaker(JBL) mod below. Luckily for the rears, the Pioneers were a direct, no-mod required fit.
