It's so difficult to judge value in audio products, especially speakers.
OK, so we know that the actual cost of wood (or other materials), drivers, and a few electronic components is nothing like the retail cost of the speaker.
But... production has to be set up, with all that that entails. And then there's the question of how you amortize all the preparatory work (some would call it research) that went into finalizing the design. There are all kinds of costs everywhere. Employees, buildings, packaging, advertising, distribution, the dealer (up to 50%), to say nothing of profit for the maker.
It would be fascinating to see a pie chart, provided by a real speaker manufacturer, of how the retail price is divided up. Then we might be better equipped to judge value.
That being said, there are plenty of instances where, to the outsider at least, there are two speakers that seem to belong in the same bracket yet have radically different prices. That's what leaves me scratching my head.
