Danley BC series (BC215, BC415, BC218)

Hey all

So, a while back I had the absolute pleasure of hearing the Danley BC215. This was the most hifi, absurdly fast and absolutely physical subwoofer i have ever heard in my life. I was absolutely blown away, especially considering there were only two of these boxes setup outdoors.

The BC subwoofer is another unique subwoofer alignment from Danley Sound Labs. Using woofers that combine into a single exit provides impressive punch and extension out of a single cabinet. Due to the physical size of the BC design’s center exit the boundary exhibits forward directivity which can be increased with multiple enclosures.

I think they are an FLH, with two drivers, with a side exit, (or 4x 15" for the BC415 or 2x18" for the BC218) designed to be used next to each other with the exits coupled.

BC215/415: -3@33hz and -10@28hz. 

BC218: -3@26hz and -10@22hz

I heard these outside, away from any walls, and it was incredible.

Do you have any idea what this design is, or where I can find a plan something similar? I would love to be able to DIY these. Any input would be appreciated!

Really, I meant I'm interested in anything based on similar concepts. I didnt mean I only was looking for the exact plan

I apologize, I have edited my post to reflect this

Iirc  recently joined member "kapha sound" started a thread on this..... should be easily found by browsing, i saw the thread the other day, should be on page 1 in one of the main forums (other designs, new projects, etc......)
