I wouldn't even briefly consider buying from a company that can't be
bothered to stock and distribute their products through retail outlets.
Because that's just so damn easy, it's a real wonder everyone can't do it.
There's no reason to believe you're buying a better speaker that way.
You're buying a speaker from a box company. None of those companies make
their drivers. They just build the box and design a crossover, then buy
everything else off the shelf.
Buying direct or not is not really an indicator of anything, but I will say this:
To get to retail (which is oh so very easy) you have to charge 10x more than your drivers cost. So if you are buying $30k speakers, at BEST the drivers might have cost $3k. The markup is often higher. If they make their own drivers it's easily 20-30 to 1.
Fritz is a really good example of some one using nicely designed crossovers and cabinets with top of the line parts and charging you a lot less than 10x. Also, they sound really really good.
By all means, please go spend as much money as you can on speakers. On the other hand if you have your own ears and prefer to spend the least you can for the same sound quality like I do, then Fritz and Tekton make a lot more sense.
Not that I like everything either maker puts out.
