Default Patent? What patent?


It looks like Wisdom Audio is about to challenge Danley Sound Labs' claim to quarter-wave enclosures that load the line from both sides of the driver. The Sage S90i in-wall subwoofer features "Regenerative Line" technology that also captures energy from both sides of the cone.

A tapped horn pretender or a harmless prior-art Transflex design?
If it works, but you don't know why it works, then you haven't done any engineering.

Got a feeling that is like the one William did.

Though I did come across another company making a dual driver PA Th, though they claimed it was based on a Danley TH design so we can assume it was licensed ?
