Within the same product line like Arc Saber series, why does a stiffer and head-heavier model charges higher than a softer and head-lighter model provided that they are made with the same techs and materials? I've thinking of this for quite a while
because the model numbers are bigger. you cannot really tie engineering/manufacturing together with marketing/pricing. esp for a marketing oriented company like Yonex. most racket cost them probably $10 to manufacture. they are free to set any price on them as long as ppl pay for them.
^that. The companies monopolize (not sure if it's the right word for it, but something along those lines) the market. They can set prices up to whatever they want as long as it makes profit. What's the difference between making a Voltric 7 vs. a Voltric 80? Materials probably cost the same (excluding R&D costs). The fact that the VT80 is a 'better' racket than the VT7 makes people want to buy the more expensive one because they deem it worthy of their hard-earned money. The only real difference here is the profits being made by Yonex, or whichever company is doing it.
How can the stiffness differ if the material is the same and the weight as well? (tapered stuff aside) There is either more material or a higher grade to make it stiffer but of course this difference in cost is less than the pricing difference ... so in the end it's all about product positioning (the marketing side).
