Timbre matching question

[HTRookie]

Hello,

As I understand it (as a neophyte) choosing drivers that match in timbre/tonal quality is critical. So.. for a system used for 70 % HT and 30% music, is it a prudent approach to use identical drivers for the mains and surrounds, even though the surrounds do significantly less work?

I ask this because I am trying to narrow down which accepted/proven designs to pursue, and if I can save some loot by using lower cost drivers for the surrounds, then I can put more resources into the mains-where it matter most ..


I thank you for any advice you can offer here
