In my experience Klipsch isn't much different. I haven't heard much of the old stuff from Klipsch, which has been better, but their new stuff is very bright. They rate their speakers as having very high sensitivity and it must be from 3khz and up, cause that's what I hear. It's pretty bad.
Other reasons are size and complexity adds cost to the speaker, so its a harder sell.
Another is people think large woofers are "slow" and bad at midrange.
Nothing wrong with the statements for what they are. And nothing wrong with the fusion pure for other SEOS kits for what they are. But as Marty said, it depends on your requirements. If you have the design chops, time, and money, a SEOS based speaker that can whoop the statements could probably be arranged
3 way using hi end parts with careful XO design. But I've never heard the statements either. Sometimes everything just comes together.
Great points, stigma is right.
Many of those individuals don't realize is when pros need accurate, large scale dynamic playback, for mastering, mains mixing, they incorporate waveguides/horns, 15" two ways, etc. There are dome HF exceptions from ATC, Quested, etc, but they come with inherent limitations.
There are poorly designed horns, a lot of them. Similarly, there's poorly designed dome/cone speakers too. But once one experiences a properly executed design of any type, in an nice acoustic environment, with adequate dynamic capability, it doesn't matter how it's approached, the end result justifies the means. Engineers don't experience harshness or horn honk in two-way Kinoshitas, or JBLs, or multi-way monsters like Westlakes, or Genelecs, allow someone to experience those and ask them about horns/waveguides.
Here's the Kinoshitas "slow" large woofers, and harsh honky HF
Sure, an extreme example, point being a bad speaker is a bad speaker, regardless of the overall design approach. Many enthusiast mistakenly associate design features with certain sonic attributes.
