Of course, everything is simple in design. You can improve upon a product to to a point. Like I said, it's above that point you pay for useless shit such as "materials", "technology" and "preference". The same applies to shoes. I have I think 7 pairs of shoes: Asics running shoes, Adidas tennis shoes, Adidas every day shoes, some dress shoes and two pairs of boxing boots.
The materials in these instances make all the difference. A hard leather dress shoe wouldn't be very conducive to going 10 rounds, much like a high support running shoe with cushioning inserts is more practical than flat soled tennis shoes when doing roadwork.
Speakers, however, don't really benefit much beyond standard building materials and technology. The current knowledge about how to build the ideal loudspeaker has been uncovered so far, and audiophile companies do nothing to give anything new to the field. Rather, they take that knowledge, seldom apply it, give the cabinets some fancy looking bits and baffles and call it a XR29 or something else "technical" sounding.
The people making advances in loudspeaker technology aren't the guys building the speakers that look cool, but the ones in the garage testing out things that may not look great, but sure as hell sound better than Wilson puppy speakers with god-awful diffraction.
