Tech That Flopped!

Donvito,

1 - The point is, acoustic suspension, since it’s commercialization by Acoustic Research, is one of the two most common technologies used in home hi-fi speaker systems. Bass Reflex accounting for the rest, and horn and TL speakers a fraction of the total.

2 - Can you point me to any sealed speaker makers who claim to not use acoustic suspension?

We are talking about cabinets and dynamic drivers here, right?

Any current LS3/5A type speaker does not make that claim. BTW,please name the ones that do!

"Two Bose 901 direct/relecting speakers create a sound pattern that is larger than the room itself, almost as if you were listening to 8 separate speakers." I bought the coolaid, owned these speakers and loved these speakers in the 80s. Regardless of how speakers are measured, not all people will like the same sound, and so many speakers and brands will have fans. That’s cool with me, I think it’s fun and enjoyable. BTW Omar Bose developed an almost perfect suspension system for automobiles that was never implemented. Go figure....

First Volt GM vehicle was made in 1996.

Donvito, they don’t because "acoustic suspension" is completely synonymous with "sealed." That’s the established convention.

I’m not saying new technology is not possible, but that I have never seen a single sealed speaker which did not rely on the same physics and models as an acoustic suspension design,so.... they’re the same. :) When you run a speaker simulation tool (WinISD, Bass Box Pro, etc.) there is no "sealed" option that is not also "acoustic suspension."
