BC412 Subwoofer
 
Danley has a new sub on their Facebook page:

https://www.facebook.com/DanleySoundLabs

No details on how it works, just a video. I think it's Ivan in the video, and he says something about this being a prototype of 'a fascinating approach.'

According to the video, "this uses a completely different alignment than anything we've done at Danley Labs"

Quad loaded FLH, large frontal boundary area.
Gets loud, rolls off below 40 Hz.
Also known as the "IHOP", intense horn of punch.
A fold pattern like this would probably get the FR it has with the right drivers:

A rehash of the BDEAP style methinks.

Art the driver hatches appear to be on the outside corners.

If anyone's curious about the bdeap, check out the patent:

Patent USD524797 - Loudspeaker - Google Patents

IIRC, there's another one too, but I'm too late for work to look it up.

Also, the patent for the DSL 'layered combiner' is online now

Freddy needs to re-post his Karlson doing a mean TP 'dance'! ;)

Could you post a link, please?

I'm assuming: Patent US20120328140 - Horn enclosure for combining sound output - Google Patents

edit: Ah! I assumed right. ;)

Hey,
I remember before the holiday's Tom said there were several patents about to issue. I'm no wiz at patent search, but I only see one for the combiner around that time frame...
