well, somewhat. A $50 Boss Audio speaker vs a $150 Alpine Speaker are different in both quality and sound quality - and price dictates that. One costs more to make.
The R&D on the Hertz Mille is paramount. The finite element analysis (FEA) and engineering done is substantial, more than most other speakers on the market. The result is, in essence, a reference monitor.
Price does reflect the build quality and materials used. A Focal Utopia Be set is more expensive due to the construction process, materials, etc. More expensive component sets usually feature more expensive crossover networks, with better quality capacitors and inductors. Same is true for home audio, pro audio, etc. Sure, there are brand markups like JL Audio, and some people like to buy a name (i.e. Bose).
Bose is an excellent example that price does not always reflect quality or sound quality.
To a point, sound quality is totally relative. What I like is different from what you like. We each have our own preferences. How I install my speakers is different than you. Installation largely determines the overall performance anyway. If you're not willing to take the extra steps to install a speaker properly, then you won't get everything out of it.
In the end, you should listen to a speaker before you buy it, or be willing to buy/sell several sets before you find the one that suits you - if your goal is sound quality. Studying the specs, reading reviews, etc. can help you make an informed decision to a point, but unless you hear them, you're trusting stranger's ears.
