Slow down and read my post, very slowly. You're simply saying exactly what I am.
1. That profit margins and other costs mean that the actual product is worth much less - my quote is 30% yours is 90% - I can tell you that 90% is not a realistic cost. When I say cost, I mean cost to manufacture. On these speakers do you want to look at Logitech's books? If not, here is a breakdown for their 'flagship' the Z5500:
You need a calculator and some quick checks on quantity pricing, plus a reasonable knowledge of what's what. $100 worth of drivers, boxes and parts in a $299 speaker. There is no logic for reducing margins on lower cost products as the fixed cost remains the same. If not 30, definitely not more than 40. Chain margins, marketing and distribution suck down about 50% of the cost.
Here is the Logisucks video for the 623 -
2. That the Logitech in this thread might indeed sound better than the Sony, but not twice as good. I do acknowledge that many will be happy with it, and that going by the way this market is developing, there's room for all sorts of questionable products. Understand that computer speakers, specially bin-boxes with boomy subwoofers crossed over high will never, ever sound good. Never.
It costs money to make a decent product. To the question of cars, all of them get you from Point A to Point B. The experience however, is remarkably different. The big question is the importance of that experience to that buyer. Using that same category as an analogy, would you compare the BMW to the Verna? Why would you do that? They are not going to be on any sane shopping list together.
Finally on the budget. Frankly, everything under 10k is a washout. I've haven't heard one speaker system under 20k that I can even recommend, so good luck with that. The way costs have spiralled over the last few years, manufacturers are cutting so many corners in their products that it's just not funny anymore. A set of speakers that cost 10k five years ago, costs twice that. What do you think is left at the bottom of the barrel? Why do you think good speakers have escalated in price? Because costs have. For cheaper speakers, what are they doing to keep prices down? I'll give you a hint, they're not cutting back on margins, or on marketing. They're simply castrating products.
Good Luck with the search.
