There appears to be a great deal of thought and tuning involved in the cabinet bracing and materials.
No, there certainly is no intelligent thought involved. There is a great deal of preying on stupidity and ignorance and milking people for their money.
Listening to a Bosendorfer piano VS a Steinway is night and day. They are both pianos and they both have hammers hitting strings to generate sound.
That's because they are instruments used to MAKE sound. Speakers are not instruments, they are tools to accurately reproduce a sonic event.
Resonating speaker cabinets as if they were an instrument has always been a completely ridiculous idea, and continues to be a load of horse manure. No competent engineer would ever put their name to such an inane and fundamentally flawed design theory because it completely eschews any hope of accuracy or quality.
Why would you want your speaker making everything have the resonances of a violin or a piano?
Trend or not, it's stupid.
American Idol is also a trend. The Backstreet Boys and the Spice Girls were a trend. Do you also want all your music to sound like that? Gwen Stefani is a trend. And this idea is also BANANAS.
